Martin Luther King Broadcast Causes Controversy

Posted on by

School board member and radio station manager attacked by ADL, receives death threats for MLK commentary

by Kevin Strom

A GUEST EDITORIAL — based largely on my exposé of Martin Luther King — has been airing on Greeley, Colorado’s KELS-FM twice daily in the days leading up to the federal MLK holiday, and the sparks are flying as the Usual Suspects try to get the truth off the air — and punish the man responsible for the broadcast.

Brett Reese (pictured), who is a school board member and director of the local school district, runs Greeley’s KELS 104.7. He says he regularly broadcasts guest editorials from listeners if their facts check out. And, he adds, in this case the facts did check out when he looked into them: “Martin Luther King, Junior” is an assumed name; King had numerous and intimate connections to high-level agents of the Communist Party; King misappropriated funds contributed to his “religious” charity and spent them on prostitutes and drunken orgies; and King was a plagiarist who cheated to obtain his PhD.

FRRL Recognizes the Liberty Net

Posted on by

The FRRL — a Web site whose acronym stands for “The Future of Radio and Radio’s Legacy” — has published an excellent article encouraging its readers to check out the Liberty Net. Here’s an excerpt, but do visit the FRRL site for a great array of radio-related features and videos (and much more):

I CAN AGREE WITH the sentiment below – so many amateur radio conversations are vacuous.   How about taking it up a notch and get amateurs into the national conversation on topics of the day?

A past president of the ARRL said that a renewed focus on technology will reawaken the relevance of Amateur Radio.  Will it?  Or will this just drive Amateur Radio into a smaller and smaller niche market on the margins of society?

Spy Numbers Station Mystery Solved

Posted on by

by Kevin Strom, WB4AIO

AN ELECTRONICS collector in Germany has created a series of videos showing us the actual hardware used in the at once ubiquitous and mysterious “spy numbers” stations emanating on shortwave from Cuba (even today) and from Eastern Bloc nations (during the Cold War).

Apparently the technology used by the ’80s consisted of digital voice samples on EEPROMs, and paper tape (of the same kind used in my high school computer lab circa 1972) for the actual encoded messages.

Back in 1989, some jokester put on a faux “spy numbers” station on 7425 kHz (and a few other frequencies) that sent messages read by an accented female announcer consisting of Mexican food items instead of Spanish numbers — “Attencion — taco… burrito… tamale… tamale… nacho… — final… final…” Hilarious.

Here are the six videos followed by the original author’s commentary:

A Tribute to Harvey Heinz, W8MPB

A scan of Harvey's signature from one of his many "care packages"

by Kevin Strom, WB4AIO

THANKS to Mike, ex-N3GVA, some precious audio files were recently rescued, and we once again have access to the recordings of W8MPB, Harvey Heinz, made during his final days with us in March, 1999. We also get to hear KE2LO, W9OAG, N8ECR and other voices which we sorely miss on 3950 these days.

Liberty Net Now a Household Word

Posted on by

by Kevin Strom, WB4AIO

WHILE LOOKING for receivers on Ebay the other day (yes, I do dream about setting up an amateur radio station again some day), I noticed a nice Collins R-390A for sale.

Reading the advertiser’s copy, I was pleasantly surprised to see the receiver extolled as “sweet” for listening to “the Liberty Net Saturday evenings on 3950.”

Now that good reception of the Liberty Net is a selling point for receivers on Ebay, what’s next? Mention of Liberty Net capabilities in ads for the Flex 5000 and other transceivers? — mention of nulling and identification of would-be jammers of the Liberty Net in antenna ads in QST?

Seriously, though, the Liberty Net meme has saturated the ham-radiosphere and is making its way via SWL into the society at large. That’s a good thing.

Out of the Past: WB4AIO on ‘AM-ology’

Posted on by

by Kevin Strom, WB4AIO

THANKS TO an anonymous listener and the Audio Vault at amfone.net, we now have a audio clip of my AM station, recorded while I was living in Rochester, Minnesota in 1996.

At the time I was running my highly modified Kenwood TS-440s on 75 meters into an Alpha 77D at about 300 Watts into a 150′ inverted L antenna that just barely fit into my small city lot. (All that gear is now gone — stolen from me along with nearly everything else I owned.)

The signal isn’t bad considering that it was presumably heard a thousand miles away on the East Coast. You can hear the recordist adjusting the bandwidth (sounds much better in the wide mode) during the segment. I’m discoursing on ‘AM-ology,’ a field which certainly deserves further study!

Birdsong Radio

YEARS AGO I joked that the next niche radio format to be attempted would be continuous bird calls. I never imagined that it could actually happen, but it has, and the results are quite pleasant.

Apparently one of the Digital Audio Broadcast channels in Great Britain (yes, they have real over-the-air digital radio in the UK, not the dysfunctional “HD Radio” that the media moguls forced on this country) started broadcasting ambient bird calls and other natural forest sounds about a year ago, and it developed quite a following. (I have no idea if the station’s creator, Quentin Howard, ever heard of my decades-old suggestion or not.)

The AM-864U Broadcast Limiter

The AM-864/U broadcast peak limiter

by Kevin Strom, WB4AIO

THE AM-864/U broadcast peak limiter, which I purchased “new surplus” from John Meshna and Company in about 1974, was my first foray into true broadcast audio processing for amateur radio. Like my TCS transmitter purchase from them, the unit was beautiful and flawless out of the box. It cost me $35. I sold it in the 90s (probably a mistake) for about $100. It now has acquired a “reputation” in the recording industry, and good ones sell for over a thousand dollars.

It’s 600 ohms transformer-coupled balanced in and out, with a simple all-vacuum-tube and all-balanced audio amplifier and peak rectification and gain reduction circuit. It was built in the 1950s by the Federal Television Corporation (some were built by other contractors, I am told) for use in AM and shortwave transmitters run by AFRTS, the Armed Forces Radio and Television Service. It came with a manual, the most hilarious aspect of which was its instructions on how to destroy it (“use axes, knives, machetes, flamethrowers, incendiary grenades” etc.) in case it fell into “enemy hands.”

My First Hamfest Purchase Now a Museum Piece

Posted on by

by Kevin Strom, WB4AIO

THE YEAR WAS 1973. It was my first hamfest. I was so young I didn’t have a driver’s license and my mother drove me to Gaithersburg that crisp October morning. I met WA3PUN, Ed Bolton, there. He was one of the AM amateur operators that I’d just started talking with on 75 meters. And I made my very first hamfest purchase — a shiny new-looking 1950s military surplus receiver, a Collins R-395, part of the PRD-1 direction finding set.

Now I notice, thanks to the Declan McCullagh photography site, that an R-395 that looks exactly like the one I bought and added to my Viking Valiant / BC-610 / DX-150A HF station is now enshrined as an exhibit in the National Cryptologic Museum in Laurel, Maryland. Time passes, and what was once just an old yet interesting receiver is now a notable part of history.
