Sunday February 28, 2021 9:15 PM CST -- Coming Cut Backs
As temperatures head above 60^oF during overnights, the Blog, Website, and Radio Server will close in early evening Central Time as an energy saving measure to recover from the expensive winter. The KDX radio services have been operating 24-hours daily as a boost to indoor comfort by warm air blowing from the power supplies, but when comfort arrives freely through better weather there'll no longer be a purpose for after-hours operation, so we'll only be with you during daytime. For at least a few weeks we're still under cool conditions with temps having climbed from near zero and now bouncing around the freezing mark, but the trend is upward according to bird movements in the area.

Sunday February 28, 2021 6:31 PM CST -- Viola Concerto
Odd that in so many years I've never paid attention to whether there are any viola concertos, especially in that I am a student of the violin and happen to know that there are over 3,000 violin concertos.   Music for violin and orchestra is always well liked by audiences not only in classical concert music but also in music for movies and light music for easy listening. By comparison a viola is observably larger than a violin and emotes a lower range, serving as the bridge between violins and cellos in the orchestra. Easily enough I asked YouTube and a whole new feast awaits.

Friday February 26, 2021 2:57 PM CST -- Labels and Titles
In addition to the string of audio programs streaming from our online radio server a meta-data generator posts text descriptions of what's playing now and the genres or types of programs offered by the station. Up until now our genres have been listed as News, Talk, and Companion. Today we added another: Artificial Music. I'd like to explain what I mean by it. KDX carries overnight programming from independent music producers under many descriptions including ambient, experimental, drone, soundart, noise, electronic, avant garde, musique concrete, industrial, and difficult music. What I wanted is a single term encompassing them all, and the solution is 'artificial music', a common factor. This Artificial Music comes not only from Disperse Dispatch, a series we've written about, but from the live stream-source linked here all under a Creative Commons license.

KMOX sure gets out, I seem to get them every night with a good signal and little fading, and dynamic sound, if a little metallic.
To which I, Carl, say... KMOX sounds dull to my ear compared to local KTRS the Big 550 which sounds brighter. Also, there are two female announcers on KMOX whose voices sound like dragging tail pipes.

Wednesday February 24, 2021 5:29 PM CST -- An Advertisment for Ad Blockers
Boomer Sales Talk on Blocking Sales -

Advertising. So many eyes are on the net, it's the cash machine of today. I agree, with network television, local radio and newspapers, ads were kept 'in their places', you had more choice on whether to look or not if the ad interested you, or turn the volume down. Here's my advertisement for ad blocking.

Anyone can fight back with ad blockers, plug-ins for the browser that allow you to control what ads you see.

I've gone on and off of ad blocking, since 1999 when pop-ups became the great annoyance, and I used Junk Buster and Proxomitron. People finally got annoyed enough about pop-ups that sites reduced their use, but then came Flash ads and other new formats, like ads that show when you click a link.

Advertising got so intense a few years ago that a "good ads" coalition was formed to clean up 'bad' ads, but it seemed to be more about consolidating power with established ad companies than reducing ad levels. They seemed to reduce temporarily, but have been creeping up since.

I can't recommend which ad blocker is best, but I have Firefox browser and use uBlock Origin as my main blocker and I like it. UBlock reduces the ads seen on pages by using a block list. Some blockers are manual, see an ad you don't like, you can right click to add it to your own block list.

I don't know if ad blocking will help with your problem at Tubi, but you can probably find a setting or a blocker that will work with it, I would imagine. Yes, it's a little bit of work to block ads, but I consider it to be part of the general maintenance of my computer experience.

Robots, that movie sounds like interesting sci-fi. I don't think I really like the idea of robot companionship myself, you'd always know it's programmed, just like it was no surprise when IBM's Deep Blue computer 'won' a chess match with Kasparov. Programming doesn't seem to go with sex robots, sex being such a biological interface.

Biological processes can be ugly too, but as animals we deal with it. Maybe companion robots should start out as pets in our homes, like in Woody Allen's movie Sleeper, they had a dog robot named Rags that talked.

Actually, Rush Limbaugh started on another toy, not a Radio Shack microphone, but a full plastic console transmitter and receiver, the Remco Caravelle. It was a small 3 transistor circuit dressed up in a big time shell for maximum appeal to a kid DJ's dreams.

Some broadcasters are driven more by the technology of a radio station, and for others it's the programming or performance. I've seen it in studios over time, some will come in and see an on-air microphone and they're ready to go live and are ready to talk about something or tell jokes. Others are concerned about broadcast power and what kind of tubes are used in the transmitter.

I like both, but I'd rather have a tour of the station's technical plant and antenna farm first, I want to integrate myself and what to do for programming comes later. That makes sense, the tech of radio is my specialty.

It was like that from the beginning, my parents were both into radio listening, and I noticed the magic of radio, voices would come out, and and you could change it to different ones, neat! This was at age 4-5, as was seeing mom's kitchen radio, and looking over the counter at it, eye level, seeing "54" at one end, and why was the 4 placed higher and written smaller on the dial?

When I got my Radio Shack broadcasting kit, I'd play music through it, and go to a radio in another room and listen, it was fun, I was on the air. I thought that was something special, there are many DJs, but who has their own transmitter and broadcasts at home? Nobody. I thought that was unique, lots of potential here, when I was 12.

I think we've seen lots of tech people on the Part-15 groups because the groups are a concentrated source of info on how to get on the air. When people get their needs met and they're on the air, they're free to program and don't need the groups any more, a kind of natural selection.

I like to see that, it means they're putting their time into their stations, and I agree, if you have the drive to build a great station in your local community, you shouldn't even be on the groups, you should be working on your station! I think that's why we're left with the kind of cranky, emotional, biological personalities that we have on the groups.

I like where you wrote that AM going digital is like putting encryption on it, so true, because you need an officially licensed chip to be able to listen to it. People don't consider what that means, because it's then not truly radio accessible to all, where even just a diode can pick up a normal AM station and listening is universal.

That's the powerful message that should be broadcast to every interested party, to think about why analog radio shouldn't be replaced with digital.

I liked reading Rich Powers' description of triad grounding. I guess that was something proposed and tested as an idea, but TIS installs I've looked into don't use it, usually it's just a simple mat of ground radials around the antenna, each 10-20 feet or so in length.

In difficult grounding situations you probably try other things, but it seems the radial ground is well established, and it works to get the required signal strength, with a local grade signal out to about a mile. Grounding is a bigger issue on the low end of the AM band though, so maybe Triad is better there?

When we were involved in professional advertising the emphasis was on appeal; ads appealed to men by populating them with beautiful models by which we mean women, appealed to women by suggesting happier homes and smiling families, appealed to children by showing off brightly colored toys and sweet tasting cereal. Promised success and pleasure. But advertising today in this internet age stands in the way of ready access to the actual content we're trying to view by rudely attempting to grab our attention and interrupt our concentration. Ads nowadays show annoying people badly groomed, adult actors acting childish, ugly stereotypes clownish in poor stage makeup talking by untrained voice, acting out simplistic and improbable situations and repeated incessantly. Advertising today is detrimental to public health.

Saturday February 20, 2021 3:43 PM CST -- Do What I Ask You to Do -- Zat is an Order!!
Tubi.tv has a large selection of free movies and their commercials are heard at a lower audio level compared to other free movie sources which keep movie levels on the quiet side while blasting commercials loudly enough to demolish the house. Perhaps as a recovery mechanism following the Trump Presidential era we've been delving into Tubi's large assortment of 'Nazi' films. It is unendingly fascinating to see how circumstances turned personalities of the most cultured people on earth at the time into authoritarian killers of nightmarish proportions. Clear traits of the same thing can be seen within the extreme right wing of our recent crop of Christian Nationalists who find themselves prepared to 'do 'whatever it takes' to serve their bellicose masters. I'm allowing 'knowing how to drive' and 'being capable of wearing shoes' as signs of culture in the American case, whereas the Europeans knew Wagner, Beethoven, Hesse, Schopenhauer and so much more. We might add that modern day fascists are semi-literate with computers.

Most recently we're painfully attempting to watch a film set in 2050 subtitled "Customize Your Lover" about the popularization of sex robots in society. 'Painfully' because the dialogue is nearly inaudible compared to overly loud music and sound effects, but some originally eerie scenarios have arisen such as a man becoming obsessed by his brother-in-laws sex robot and a visit to a singles bar where the walls are lined with inanimate sex robots of every size shape and gender waiting to be approached. While words like 'gross' and 'sleazy' have been used to describe human biological sex, we expect that more grim and dreary words will eventually apply to sex with electronic machines.

Rush Limbaugh sounded to me like a man trying to talk after eating too much for lunch. His palaver came across as lazy avoidance of any fact checking. He seemed badly informed and averse to intellectual reflection. But he made all that money so somebody must have thought he was up to the job. And he's been credited with "saving AM radio" while at the same time AM radio has been abandoned by persons of taste and is on the brink of going all digital in a last ditch attempt to save itself through encryption finally rendering AM radios obsolete.

Monday February 15, 2021 5:42 PM CST -- Snow Bound
I have a science question. As you've noticed, water is translucent like glass and you can see everything in it or on the other side of it. So why is it that when water turns to snow it makes everything white and allows no view of what lays within or beneath?

Now a policy matter. I might ban sex robot jokes on this blog. I mean, it's the kind of thing that lends itself to humor, and no doubt ribald robot jokes will become common place, but I'm not comfortable about it. Let me demonstrate the sort of talk we might want to block...

So, my robot freaks me out when she doesn't blink, but when she blinks there's a clicking noise which is very distracting.

Come to think of it most of my reservations have to do with sounds. Especially whirring noises whenever she changes position.

Monday February 15, 2021 2:04 AM CST -- Radio Companionship
We're up and about somewhat early during a widespread winter storm spead across much of the U.S. The conditions at our location in the Mid-Mississippi River Valley are not as treacherous as many other locales. Our temperature is 1^o with snow starting and possible predicted depth of 5-or-so-inches. Ian Punnett is interviewing an author of a book about sex robots which sets my imagination into several tangential directions, but centered mainly on musings about non-human companionship. It occurs to me that the radio has been long considered a surrogate companion.

An old Crosley Cathedral radio comes up by Googling 'companion radio', as does Public Radio's now defunct 'Prairie Home Companion'. We typed 'companion' into the genre box at the two radio directories (xiph.org & steamcast.com) that list our own KDX Worldround Radio but came up blank, so as of this moment we're adding "Companion" as the third stated format of KDX along with "News, Talk" and plan to promote general acceptance of the category.

There is no denying the fact that having a radio station in the house providing favorite programming everyday is a very pleasant source of companionship and that's the main thing about it. Would a robot be jealous?

As reported on the Artisan Radio Blog the part15.org forum was down yesterday, perhaps foresignalling its eventual closure as low activity on the forum places it on a deathwatch. Also from Artisan comes bleak news for radio listeners in the Vancouver, British Columbia, area in Canada. Some of the underhanded corporate strategies described remind me of goings on I've witnessed here in the "lower 48". Several years back the switchboard operator of a network TV station informed me that hundreds of calls poured in complaining about a decision to yank the Dick Cavette Show in favor of running old movies. The operator was instructed to ignore the calls by not keeping a record of them. Purpose of the change was a gain of two extra commercial minutes every night. And more recently, despite making the bar very high for qualifying to license an LPFM station once many such stations clog the band some of them immediately switched formats from the "service to the community" promise which greased their application to common music formats no different than found on commercial counterparts. A few of the non-commercial LPFMs are heard airing outright commercials in violation of FCC rules.

We'll no longer need to 'borrow' 89.5 away from KDX-FM and our main broadcast channel. During the setup we were reminded of what differentiates the FM1 from the FM2; there is a noticably high noise-floor heard as a 'whishing' sound, otherwise the audio is excellent. If C.Crane comes out with FM3 it should include a mono button to shut-off the stereo generator. Seasoned low power hobbyists know why.

Artisan Radio has been working on a project aimed at producing RDS (Radio Data System) via a nearly costless assemblage of software and computer hardware and may have solved the last mile by way of a $12 device, a Moshi USB-C External Sound Adapter capable of 192 kHz sampling. This is ingenious on several levels. The reason for the high sampling frequency is the need to pass the upper sub-carriers required to carry the data. The USB-C device does just that and only that, and although marketed as a headphone utility can just as easily feed the audio input of an FM transmitter. Also, the choice otherwise would be an expensive sound card with all of its un-needed inputs and other frills amid possible shortage of card slots in the computer. Our link shows a chunkier price, so somewhere else there's a better deal.

Thursday February 4, 2021 11:03 AM CST -- Things of Thought
I, Carl Blare, your blogger, think about many things. I actually do far fewer things than I think about. This morning is rainy and I'm thinking about live radio. There's an irony in the fact that most of us who build and operate low power radio stations do so in part because of fond memories of the great personalities and DJs from radio's past who did live programs, yet the programming on our smaller stations are pre-recorded audiofiles from automated playlists. Those few who've broadcast live on part 15 (low power) or streaming stations are quite rare and hard to find.

Years ago while first constructing KDX Wordround Radio I streamed live a couple times but looked at the activity window on the computer screen and saw no listeners connected, so I knew I was talking to no one. It became easier somehow to simply record my show and play it back while I tended to other business. Now, in the nostalgic rain, I'm pondering a daily live show on which I'd jibber jabber about current events, observations, opinions, and other ramblings. Hmm. But look what's happening. I'm blogging about it. This thought will probably never make it to air.

Tuesday February 2, 2021 6:51 AM CST -- Fear and Interference
Small radio stations authorized under FCC rules Part 15 find themselves in a somewhat precarious category given that the main purpose and intention of the Part 15 section is to manage, control and alleviate interference across the radio bands. Of course 'interference' is understood to mean 'confliction' with transmission and reception of the 'more important' licensed radio and television services. License holders and listeners alike are offered the courtesy of a reporting system for complaining to the FCC about percieved interferences.
In actual fact the Part 15 rules define 'how much' interference a given device may generate before it becomes a 'harmful' interference. Interestingly, a proviso of those rules holds that a Part 15 radio device 'May Not Cause Interference' yet 'Must Accept any Interference (may not complain about it)', while at the same time any person acting as an individual is invited to make interference complaints.
KDX has been radiating acceptably low power and very polite interferences since 2007 and frequently issues apologies, excuse me's and I beg your pardons in the hope that no one within listening range avails themselves of the FCC's interference response team.
