Do playgrounds still have teeter totters? During the socially active years a visit aboard a nearby teeter totter provided memorable fun around a fulcrum riding up and down face to face. The expression 'teeter totter' would make a suitable metaphor for a web forum. Imagine 'Part 15 Teeter Totter', sharing the ups and downs of the low power radio lifestyle. Maybe Moderator Mark could do an Elon Musk by purchasing Part15.org and renaming it 'The Part 15 Radio Teeter Totter'. Then the Twitter people could 'tweet' and the part 15 folks could 'teet'.

Wednesday April 27, 2022 12:45 NOON CDT -- The 2 CCrane FM Transmitters --
CCrane FM1 was briefly available until replaced by FM2, bringing two notable improvements: FM2 has an extremely quiet carrier, which is to say that the audio is received with very high quality signal-to-noise characteristics. The FM1 had a hissy noise floor that was conspicuous during silent moments in audio modulation. The second improvement was made to the LED modulation light, the FM2 registering a blinking green light in response to audio modulation and red light flashing on over-modulation. The FM1 had no visible indication that audio was present until overmodulation flashed a red LED.

KDX utilizes two CCrane FM transmitters, one of each model. We've been using the FM2 as a daily workstation monitor for our radio station, and have just restored the FM1 to service for monitoring audio from our newly installed 2nd computer. Right away we became aware that the FM1, in addition to its hissy noise floor, has developed a crackling noise like frying bacon. This is particularly noticable during quiet audio, frequently encountered in web listening, a good example being the live YouTube coverage from the Johnny Depp courtroom proceeding with long stretches of very weak audio. The likely cause of the crackling noise may be a defective electrolytic capacitor which will be difficult to locate and replace because of circuit miniaturization.

See:  All the News That Isn't Fit to Print 
Artisan gave two reasons why some Twitter tweeters tell lies, and The Blare Blog suggests two more reasons: those being commercial advertising and organized religion. I know all about both since I worked in each field during the course of several careers. In both ads and holy work we appeal to the human imagination which is quite pliable. Our job is to prompt people into believing what they want to believe. Even devout believers of one particular faith would agree that all of the other religions are speaking falsehoods. There's no reason why you should believe me, but Elon Musk has spent 46-billion to allow me to spout off.

Tuesday April 26, 2022 10:31 AM CDT -- The Magic Band --
Listeners with amateur radio experience will know that the 6-meter band is known as "the magic band" because of its extraordinary DX characteristics under certain conditions. As well, those with amateur knowledge will realize we're talking about the 50 MHz region and they'll know what "certain conditions" and "DX" might be. They'd know a lot more, such as how the "old FM band", VHF channel 2, and frequencies previously used by cordless phones were neighbors. This whole topic came up when we needed a last minute program-choice to fill an hour of air time on KDX and arbitrarily found "HAM Radio Concepts podcast" which happened to devote their show this week to 6-meters. Here at KDX radio our engineers have their eye on a Part 15 license free low power channel at 49 MHz, allowed by the FCC, which we'd like to employ as a studio-to-transmitter-link (known as STL) to supplant our 2.4 GHz Wi-Fi audio system now in use.

The "old FM band", 42 - 50 MHz, started in 1945 and was closed in 1947 when the new FM band was opened from 88 - 106 MHz. The frequency shifting had to do with the advent of VHF television which gobbled up many megahertz.

The lady on the phone had a probably Latin American accent, but I didn't ask where she was stationed, so I'll guess wildly that it might have been Argentina. She was my contact person at the sales site that rejected my login attempts where I want to buy shoes. Of course I am certain my telephone personality has her wanting to call me back and make it personal. While I'm waiting for that call I happened to think, 'The show is over but I'm still in the theatre', and I know what that means even if it's not clear to blog readers.

Now we have a grip on what's going on with this stupid but irresistible problem getting the USB drive on the Wi-Fi router to work across the LAN. I also know what that means even if it's not clear to blog readers. The Windows 10 machine is able to download but not write to the USB drive, but the Windows 7 computer does not detect it at all. Somehow life made it all these years without having this problem, but it's here now and like any other dog I'll keep chewing on it.

Out the window is the second of two days in the 80s so that's where I'm headed before the storms come later on.

Friday April 22, 2022 8:33 AM CDT -- The USB Port on the Router --
As we've said, the new Wi-Fi router put recently into service contains a USB 3.0 port which we've populated with a harddrive taken from our broken XP tower computer, already loaded with 3 partitions full of audio files. From within the router's own software dashboard under the USB setting all 3 of those partitions are listed, proving recognition of the harddrive by the router. But, and you could feel a but coming, none of those partitions are findable on either of our two workstation computers. As a further fact, the router setup instructions tell us that the USB port can be activated via 'Samba' and/or FTP, upon which we determined that 'Samba' would be of no use because it's purpose would be to enable linking of a Windows system with a Linux outfit, which does not apply around here. FTP sounds ok, except that thus far we've been unable to figure out what to do at either workstation to get started. I should say, though, we have found an audio file known to be stored on the elusive harddrive by way of Audacity Audio Editor, but are unable to find a way of saving back to that drive. A case of temporary insanity has taken our brain hostage and become foremost in priority as we leave you for now.

So Small You Might Lose It

Wednesday April 20, 2022 6:33 PM CDT -- Reflections On Radio --
This Essay Was Written by Me, Carl Blare, on Dec. 30, 2012

In the beginning radio was viewed from the public service point of view. It was a "theater of the air" and it was a wide-area "public address system" and it was there to deliver quality sound performances and important information to the surrounding population.

The legacy of licensing stations to towns and cities is a remnant of the old system, but there is a disconnection, because the actual towns and cities no longer have a place at the table. Big owners in far away sky scrapers own the licenses and keep their eye on one spot.... the bottom line.

The bottom line is the profit line, and is a matter of reducing operating costs on a teeter-totter with advertising revenue.

As far back as the early 1960s high paid "consultants" were advising station managers to fire the creative talent, because these types were considered too independent and uncontrollable.

Consultants themselves had limited life expectancy because their reign lasted only as long as the ratings that followed in their wake.

Bringing quality to the public was drained from the discussion and in some ways was passed over to public broadcasting, but the politics have boiled most non-commercial stations down into a sterilized politically correct pudding.

The last bastion, so to speak, has been so-called "community stations", but weak signals and petty in-fighting by license holding boards of direction have overturned many of the better ambitions that lost their grip on the paddle.

Comes now the smallest stations you've never heard, enabled under part 15, and in certain ways it's the final death struggle of radio, trying to be that mature horn of plenty we all envision.

Even down here in the microcosmos there are yapping dogs sent in to nip at our milliwatts and remind us to stay within our marked area. The creative rabble must be subdued.

Tuesday April 19, 2022 6:58 PM CDT -- Here's the Up High --
People are always reporting things 'on the down low', a figure of speech which I guess calls for a kind of crouching huddle to share intimacies and sly secrets. So, therefore, it should be possible to hold an open conversation 'on the up high' when there's nothing secretive going on. Yea, that's what we'll do now.

Hey! For the past day and a half we've been crouched and huddled over two keyboards on two computers setting up this Wi-Fi router while enlarging our radio broadcast operation in the process. The second computer had been stashed in storage for almost two years and has finally become integrated into daily use thus growing our overall capability. The older familiar machine runs Windows 7 which served reliably but this newer addition contains Windows 10 which has been daunting and snarly. Like breaking in a horse we've slapped a saddle on her and been spurring it to figure out where the unamazing maze of software trails reach the information super highway. Just as we'd finally uninstalled a glut of needless frills and fancy dads and do's Microsoft sent an imposing message informing us that our version of Windows 10 had reached 'end of life' and warned us to update now or later tonight, striking terror into our brain's panic out-of-control center. Saying a few bitter nasties, I signaled back, "alright. Do what you have to do", and it did, taking 35-long-long minutes. And in the usual Microsoft way they messed the bed by leaving new glutter in the system that I'm still finding and uninstalling. It's a hate hate relationship.

Tomorrow the happy trail resumes when we attach something to the USB 3.0 port on the Wi-Fi router, creating a LAN shared drive available to all of our computers, a complication that will make life less complicated.

But it's not all about me. How's your stuff doing?

Many of the human animals who've bluffed and blundered their way into political power have such scrambled brains that they could easily 'bring it on' with reference to a final war. We're at exactly the juncture where any moment could bring the flash that would end our history. It is past the time when debating fine points has useful influence. If by sheer chance one of the idiots doesn't quite launch nuclear annihilation it seems clear that slower decline will get us soon enough through climate destruction, so why not abbreviate the experience with the one-button solution? It's not really a vote we have the choice of making; our only choice is to sit around waiting to see which it will be.

Sunday April 17, 2022 10:21 AM CDT -- Virtual Expansion --
Based on an internal study of the KDX technical operation, we have established a routing pattern so as to best apply the new Wi-Fi routing device now in active service. Our primary server-computer providing the kdxradio.com website and Icecast web stream is hard-wired by ethernet and a secondary utility computer is networked on a 5G wireless channel, thus displacing what would be a 35-foot ethernet cable. As a blog reader we realize you are immensely excited to hear about this and we pledge more such talk in days to come.

Saturday April 16, 2022 4:34 PM CDT -- Goings On --
For the first time since the beginning of time KDX has installed a Wi-Fi routing system after talking about it for a long time. We are impressed by everything about it from a technical standpoint and notice only one small and insignificant difference when compared to wired ethernet. While streaming audio from our KDX work station it generates a noticable jitter distortion over wireless Wi-Fi which does not occur when directly wired. Such things as movie audio or reception of streaming radio from other webcasters would therefore bring the same minor distortion if heard by Wi-Fi, but it's no more important than the perceptible differences between analog FM and AM, particularly since there's no nessary advantage to using Wi-Fi in our day to day operation other than as a novelty for our own technical amusement.

The subject just changed, we are now talking about music heard today on KDX with chilly sunny weather on campus. It was time to bring the piano concertos of Rodion Schedrin into our familiar zone, never having spent the time to sit them out. He wrote six of them, each around 22-minutes, and we have all but No. 5. It comes as no surprise that they are each pleasing for their originality at a time in music history when it's become a challenge to write anything new, there being only 88-notes on the piano and so many hundreds of works in the genre already established. Maestro Schedrin is in his 80's and slowly becoming a world favorite among serious composers, not to overlook several jocular works such as "Silly Limericks", the subtitle of his Concerto No. 1 for Orchestra which sounds like something from an insane cartoon.

Just as picnicers find a spot in parks, spectrumers manage to occupy slivers of the electromagnetic spectrum. We go a little bit overboard here at Worldround Radio, home of KDX and our various other radio stations, with slices of the medium wave, FM, and Wi-Fi bands, all under the authority granted by the Federal Communications Commision Rules Part 15. Today we made further incursion with the addition of a Wi-Fi 2-band router which needlessly sends and receives everything we do wirelessly over a distance of 7-inches in lieu of an ethernet cable. As a result of not using ethernet cables we have many extra ones in storage, but also retain the ability of switching to cabled operation at anytime just because we might feel like it. It's a hobby and hobbies sometimes involve doing something in a way distinctive of that hobby.You may quote me.

Boomcasting at 640 and 1240, it's Boomer:

Rad Carl,

I was always intrigued by the Conelrad stations, since radios had markings on their dials for them at 640 and 1240 kc. I tried tuning the stations in but I never heard them on the air, even testing. What I knew back then was that they were special transmitters outside of cities, with generator power and hardened against attack. If that threat came, the city stations would go off air and Conelrad stations would activate with emergency info.

Through the years I've wondered if CD stations were still out there somewhere in compounds, ready to go, or maybe decommissioned and rotting away.

A great teen fantasy would be to stumble across one of the CD stations while out hiking, abandoned, overgrown, but the equipment still in working order. We would sign on with a one-time mystery broadcast, and get away with it, and everyone in town heard it and would be buzzing about the clandestine radio station. That would make a good Hardy Boys episode. Oh, add hearing spies on the station monitor receiver, speaking in Russian accents, and run out of the building, screaming.

Now that page throws out the previous knowledge I had incurred, Conelrad was just your normal broadcast stations re-tuning their transmitters to the emergency frequencies. Now I don't know what the secret transmitter story was, maybe a different system, used somewhere else or at a different time.

What's never heard in the discussion of Conelradio is what to do about local FM stations in an emergency, I guess they would have gone off the air too?

Maybe you could set up an extra transmitter as a 'Carlrad' station for use only during emergencies. You could find lots of emergencies to use it, polar bear attack or sidewalk crack grass growth. Maintain the station and do regular logged tests..

As for the grass, man, I think Crackgrass, if you get busted for it and end up in court, tell the judge that grass was an effort to combat Climate Change since the blades were there to convert carbon buildup along the street. Well, in today's wolk climate, stranger things are being discussed, like litter boxes in schools for students who identify as members of the cat and dog community. Never mind that the story is false news, lots of people believe it apparently, the topic keeps coming up on talk shows.

You can look up Class E to see more of the theory behind it, with oscilloscope photos showing what the proper waveform is supposed to look like. There's very little authoritative information on it for puny low volt Part-15 transmitters on the AM band, as E is used mostly on shortwave and by hams at high power and up at Ghz cell phone frequencies for high E-fficiency. Commercial AM broadcast transmitters seem to use mostly class D, because that has fine efficiency on the lower frequencies used in the broadcast band. I haven't seen any Part-15 broadcast band transmitters use D though, but we should, it might be easier to tune by the average po, and yet get higher efficiency like E has.

As for college radio, you have to put yourself in the frame of mind of a teen learning about the world at large. When I finally got an FM radio, I listened to college stations all the time, and they opened up a world of eclectic and alternative music, with dee jays who were closer to my level socially and emotionally than the top-40 pros. It felt underground, cool, and just for me, something adults didn't know about.

The question could be, is college radio like that relevant now and do we need it? Kids like Tick Tock these days, but it doesn't seem to have the same intimate feel as hearing a school FM station with a small coverage area and a few listeners. You know with Tick-Tock or any of those media sites, that anyone could be watching it anywhere, and you're being surveilled and tracked wherever you go, it's not so subversive.

- Boom AM

In the Conelrad days FM was a non-issue because it had almost no occupancy and there were very few FM receivers. As to Class E, the SSTran5000 manual has an excellent write-up on what it is and how to tune it and it really works because I followed the instructions and then observed the spectrum analyzer screen and hey! Wow! That sucker is efficient, tell ya what! And another thing, I do believe the Ramsey AM25 kit may be class D. It has a 50-ohm RF output and, according to PhilB, inventer of the SSTran line and once member at part15.us, posted that he was puzzled why the 25B was designed like a full-scale professional transmitter not at all suitable for a short wire antenna. Also the 25B could be wired for 1-Watt which got some fussy-pusses really cranked. I have a Ramsey 25B and might put it on at 1710 at very very low power because I like hearing radio through as much AM background slabber as possible. 

Friday April 8, 2022 1:35 PM CDT -- Wi-Fi Router Cancelation Notice --
Earlier this week, following several weeks of research, we of KDX Worldround Radio placed an order for a difficult to find Wi-Fi6 router. Today, however, we have received a cancelation notice from the supplier telling us the router is unavailable and our account will be reimbursed. It would seem there is a widespread general shortage of newest generation Wi-Fi6 routers and it appears no further action remains open for us at this time. We surmise that worldwide chip shortage combined with supply chain blockages are at the root of the problem.

Forget the idea that radio is educational. Operating a radio station is technically about the same as using a sink. Truth is that playing DJ is the same as working the public address system at Walmart and the only reason colleges have radio stations is to provide a playroom to keep students occupied between real classes. Faculty advisors are not there to teach anything; their only job is to make sure FCC regulations are followed. There is no reason for the public to hear any of it, but being on the air serves the school as sort of electronic flypaper to attract more enrollment into lifelong student debt.

Guest column by Boomer -

Class 'E' is Classy

Class E is a real thing, created by lead engineer Nathan Sokol in the 1970s for high efficiency RF amplification. It describes a different type of circuit layout, RF drive and tuning. Tuning is done for the highest efficiency and best done by watching  for the proper waveform on an oscilloscope as you tune the output stage.

Tuning for efficiency is the key to make class E work for you, and I seem to recall a method the designer had for the oscilloscopeless man to use, peak it up, then turn the tuning screw a half turn more which should put it into class E.

As for 'duck and cover', I remember hearing about that, but we didn't do it in my school. I remember when fallout shelters were decommissioned though, and I had a few of those shelter signs you used to see everywhere.

There's lots of audio from the Cold War period, Conelrad test sounds, PSAs and the 'duck and cover' children's records out there. This site is good, though the audio files aren't working for me. You can find them on audio download sites or Y'tube.

http://www.atomicplatters.com/audiodirectory.php/

I wanted to see what bomb shelter radios were like. There were a few made, and modifications made to battery portables for low current drain and external antennas. Electronics and scouting magazines published schematics so that you could get involved in preparations by building your own low drain shelter radio in a cigar box.

This page has a lot of history on it, and I suspect there's a lot more out there..

Dogs can also suffer from fur problems, just like celebrities, with a disorder called "Canine Alopecia Syndrome." I used to have a PSA on cassette at my station from the American Academy of Dermatology about CAS.

This is Carl, long time listener and chronic caller... I always wondered how Conelrad stations could suddenly pop up at 640 and 1240 kHz when there were no regular local stations on those frequencies. It can't be easy to achieve. I don't recall ever getting underneath the little student desks but remember the teacher handing out little brown iodine tablets and having us march single-file weaving between desks to a phonograph recording of John Philip Sousa's 'Under the Golden Eagle'.

Morons have an advantage over people of intellect.

The chronically stupid, ironically, benefit in being shunned for their boorish dullness, insufferable lack of tact, blatant dishonesty and foolish superstition because no one with any sense would care to have them around. Given such wide berth, the lunkheads escape notice as they bully their way into top office while the better qualified have already scampered to a safe distance.

Tuesday April 5, 2022 6:56 AM CDT -- Part 15 Gang Activity --
A brief furor arose at the HobbyCaster Clearing House yesterday in response to recollections on the Artisan Radio Blog about the shifty 'Transmitter Challenge' from years ago. For one day only the Hobby Boys re-posted ancient diatribes against the purported Class E circuit which distinguished the now legendary AMT5000 Transmitter from SSTran, including an old poison paper by persistent SSTran hater the Late Ermi Roos. In summary, the net result of the bashing was to raise doubt about the Class E claim, carried on now despite the fact that the transmitter is no longer available. But if the Boys were such professional engineers, according to their own self description, they'd easily know one way or the other, yet their tactic is to merely scoff about it. It doesn't matter today because the Bottle Washer has pulled the flurry of defaming rants and returned to the usual riddles.

Every new morning starts with the first thing, often a cup of coffee, before taking on second thing, third thing, and the expanding to-do list stretching through the day always gaining in number until it's clear once more that unfinished plans will be set aside until tomorrow. The undone merges with falling night and mixes with a universe coming into view showing the unending depths and expanses of undoables unreachables and unknowables blinking from across time. Only sleep offers a way back toward morning for another simple beginning.

Monday April 4, 2022 6:01 PM CDT -- Beam Me Up --

With Beam Forming as a new feature of Wi-Fi6 routers can we expect personal molecular levitation up to hovering spaceships via the 2.4 GHz band? In his summary of Wi-Fi routing Artisan Radio was a little skeptical about the promise of 'beam forming' and I would have to have doubts myself, that without making any physical changes to a router or its antennas it could 'know' how to redirect its 'beam' to targeted devices around the house. What are all the antennas on Wi-Fi routers? Is it something like diversity reception in some wireless microphone receivers that smartly switch to the antenna with the best reception? No matter how smart you are, you are always outsmarted by electronics that think but keep many secrets.

Monday April 4, 2022 9:38 AM CDT -- The Ground of Radio --
The subject of grounding is up again at the Artisan Radio Blog and Mark's well moderated forum at Part15.us, as the subject of grounding is central to achieving the best performance from AM radio transmitters. There are many who don't realize that grounding for the medium wave band is a necessary half of a vertically polarized antenna system. It took me years before I came to understand that an electrical connection into the earth forms the return path needed to achieve a fully radiating circuit from an antenna. One common approach is to sink an 8' copper ground rod and attach it to transmitter ground with a short ground-lead wire. What has worked even better for KDX is to lay out so-called ground radials from a central feed point in as many directions as possible, the more the better up to possibly 60 or so. Truth be known, I only have two radials at this time, one laid toward the south, the other toward the north, yet with only that much the signal gets out many times farther than with a single ground point or no ground at all. I'd estimate a strong signal to 600', slightly feeble at 1,000' but at times heard in the far background on a parking lot 1-mile away. By adding more radials it would further improve and that day will come, if Vladimir Putin doesn't soil our plans.

Now a message from Supreme Court Judge Amy Coney-Island:

Abortion is to be abhorred. As a Catholic Judge I represent God, who wants every life to be born. The main responsibility of those among us as a result of having been born, is to live in service to life and welcome it along every stage of the way, starting with sperm. Everytime a man ejaculates he sends 6-million sperm on their way into uncertainty. If man's seed falls upon the ground, as the Bible says, 6-million lives are lost before they have a chance to begin. This court will introduce criminal sanctions against masturbation punishable by 6-million life sentences per incidence. When conception occurs involving a woman, 1-egg has a chance of being fertilized, but 5,999,999 sperm are lost down the drain. We foresee a requirement under law to immediately report every fornication to the police who will arrive to gather spilled semen for deposit in a sperm bank. We're at the beginning of sweeping changes to the Shepherding of the Flock, brought on by the Supreme Court-Catholic Hospital Tribunal. And further, we call to mind the Biblical passage: "Man passes from dust to dust", a clear indication that dust itself is a sacred substance and I intend to ban all vacuuming, dusting, mopping, or any form of dust removal. The divinity of dust is evident in the way it settles everywhere on all surfaces. Because I am a woman some have called me a witch. But I am not a witch. I am a Fire Breathing Dragon! If this Blog gives equal time to another point of view, I'll torch it and scorch it! And now back to Carl Blare.

Right. Well, as it turns out, the other point of view has backed down.

Saturday April 2, 2022 2:35 PM CDT -- Catch On Now? --
Here's what I think's been going on. As I've been browsing Newegg and Amazon regarding the TP-Link AX50 Router, listings for new routers of this model have been disappearing. A first visit to the TP-Link Official Website shows that the AX50 is not listed at all. So, looking at another promising model, we noticed that it was 'sold out'. I believe there's a router shortage, possibly because of shipping troubles and maybe even chip shortage. It's wartime in the world.

A concert by the Mankato Symphony Orchestra is being heard on KDX featuring a premier work by a contemporary composer. Strikes me that in writing the piece there was indecision at every note whether to go upscale or down in avoidance of matching something already written by someone else. Music education is a real bear these days because you've got to develop a familiarity with every piece ever written so as not to inadvertently come up with Beethoven's 5th or Rossini's William Tell by unintended coincidence. That would be a bummer when you learned your hard work was a waste of time. Heck, I came close to writing Tchaikovsky's Piano Concerto. Let's see, then we'll have a chamber music concert from Pittsburgh and finally a European orchestra doing Carl Nielsen's 4th Symphony, known as the "Inextinguishable" based on the idea that the creative spirit cannot be doused. Is that correct? Dowsed. I'll look it up later.

I remember those days. A 'nooner' was slang for a clandestine meeting with a sweet woman of one's acquaintance, possibly a secretary or other lunch hour friend. But that's not why I'm here. We've already landed the New Yorker Radio Hour and it's airing now, same one we heard earlier this morning on public radio. The program's website states that the program is 'free' and no other terms, conditions or limits are posted (that we could find). Another thing we'll pack into this fattening paragraph (the paragraph is getting fatter, not readers) is a growing expectation that the computer router we got so agitated about yesterday might turn out to be the best choice afterall in the category of AX type routers. FYI the AX designation marks routers of the most recent Wi-Fi6 variety, while 'AC' marks Wi-Fi5 or earlier models which remain perfectly compatible and handle in-home personal computing situations perfectly well. We'd come upon the TP-Link AX50 named as the PC Magazine Choice for its category and praised by a YouTube reviewer as the finest router in its class. Our circular path results from looking at what other router makers offer, all sporting less by way of goodies. We had cringed because of frustrations over disarray in the AX50 descripting (descriptions) by both the manufacturer and the sales language elsewhere. Oh! She's here now! Talk to you later in another paragraph.

Coffee with honey added sure runs out fast. Let me get some more, then I have a few morning thoughts and need to get KDX started. Hold on a minute...

Alright, we're back at 7:32 AM. That was a long minute, but here we are. The first thing that broke the silence this morning were voices from NPR which quickly drew me into a narrative about a guy who spent his life canooing rivers and keeping journals of his exploits, but was eventually lost and has never been found. It was a very riveting tale with excerpts from the man's writings read by a professional voice actor and the program was identified as the New Yorker Radio Hour. So you'll know, the New Yorker is a highly regarded magazine known for exceptional high quality writing and has for some time produced their own radio hour which now I'm determined to carry on KDX if permission allows. As I gather more information I'll share links and so on for Blog readers who may likewise be curious. Let's see, I was also going to say something about music royalties and NAB, but let's pick that up another time, KDX is behind schedule and I'm the only one on duty.

Friday April 1, 2022 6:19 PM CDT -- Notes from Vacation --

It's off to a good start on my abruptly delclared vacation and I'd like to share advice on how to regenerate and refresh following the burnout that can overcome a person when an intensive project veers out of control. Did you realize that mental concentration burns energy at a furious rate? That's true and the speediest recovery starts with an immediate nap to fully wipe the mind's slate and emerge anew in midday ready to have a second morning. New thoughts start sprouting like flower buds in the springtime. Watch also for listener fatigue brought on by excessive repitition of news stories or songs you've heard one too many times. Remember how I said that KDX has no sign off message? That's changing as our new sign off message will be "We've heard enough."

Friday April 1, 2022 2:58 PM CDT -- Router Search Reaches Impasse --

After intensive study of the current state of the art of routers and perusal of available models we had tentatively named a victor in our search. But two things have caused us to call a halt and begin from scratch.  Several YouTube router reviews reveal cautionary gotcha's endemic to the model we were set to choose, and confusing clutter in online listings at the sellers' websites have caused us to back off. Following a relaxing holiday we will resume our work.

Friday April 1, 2022 10:38 AM CDT -- Duck, Cover and Dig --

'Dig it, man' was a beatnik expression from the '60s possibly related to the forgotten icon of the cold war nuclear scare more often remembered by the expression 'duck and cover' with images of school children ducking underneath their desks and wrapping arms around their heads during bombing drills marked by air raid sirens.  In those same days the digging of bomb shelters underneath cellars also became iconic but the only remnant of such self-defense measures in our time is the tornado siren with the instruction: 'Go to a lower level of your home until the all clear is sounded'. Actually, the muffled voice from the public address loudspeakers sounds more like "Mawewahellowneyuhpladneersounded!" Anyway, with renewed scare brought on by Vladimir Putin's way of expressing himself the bomb shelter industry could be coming back. There might not be time to apply for all the building permits required to dig a hole under the house so there could be increased call for squads of property inspectors to add basements along with sidewalk cracks to their list of violations. Ironically the shelter will provide a place to hide from the inspector especially since the doorbell cannot be heard in a subterranean hole. More important is food for the 100,000 years it will take for the ionizing radiation to finally decay and butchering skills required to prepare and eat the neighbors. You may not have time to sit here all day reading blogs.

Friday April 1, 2022 9:46 AM CDT -- Disorders of the Day --

Three health disorders in current news include aphasia, alopecia and childhood onset fluency disorder also known as stammering or stuttering. COVID 19 and all its variants have moved into the background while we de-celebrate the unfortunate celebrities now marred by their trademark defects. Two out of the three inflicted parties are actors whereas the third being a politician one might regard him as a second rate actor in as much as politics has somewhat of a stage. Another political game player who went out on a disease was President Ronald Reagan who took on alzheimers the day after leaving office and stepped up from being a B actor to Academy level by retiring into the respectibilty of being stricken together with co-star and supporting actress Nancy who played the loyal wife in attendance, leaving his trail of misconduct and war crimes out of bounds. Meanwhile, the other night, the Best Actor walked off the carpet in perfect health because he's the best actor and of course not a feral unhinged bully.

Friday April 1, 2022 9:14 AM CDT -- Radios and Routers --

For about two weeks we have been pouring over router choices to replace our computer's ended-life Cisco model currently in use. We've been aided by input from a panel of computer consultants, scouring supplier catalogs, viewing YouTube router reviews and studying online instruction manuals for each potential buy. What a mess. New models are coming out every few minutes and recent models are already out of date. It's exactly like the situation with radio receivers. Although professionals like Brooce, Artisan, Mark and Boomer can recall near-perfect radios from past times, those are now long discontinued and  continually being replaced by more recent models with quality always bobbing up and down as some are deficient and others passable. I guess the design labs and marketing departments behind the products are in constant fear of obsolence which would be brought on by happy customers with stable products that lasted a lifetime. We as customers have been trained to yearn for the latest in upgraded newest model number. Version 3.0 is yesterday, version 4.0 was 2-minutes ago, version 5.0 is already being shipped, version 6.0 is about to be announced.  The pursuit of happiness is a self-thwarting endeaver.
