This was a fairly typical session of the Old Military Radio Net. 3885 kHz AM 0500 local on Saturday mornings. (Distant listeners can tune in via WebSDR.) This clip shows W3EMD, N2CQR (me) and, N1SNG. Buzz W3EMD from the Hudson Valley of New York was on with his KWM-1. Normally he uses a BC-348 powered with a Dynamotor. Last week he told the group that someone had COMPLAINED about the noise that his mic was picking up from the Dynamotor. Geez! I told Buzz that we had been commiserating with him about this on the SolderSmoke podcast. Later in this morning's session I heard WU2D, WA1HLR, AJ1G, and others. I reported on an emergency De-Oxit spraying of my HQ-100's band switch, just minutes before net call up. I also noted that I had found a crystal for 3885 kHz; the radio gods have spoken (TRGHS).
Podcasting since 2005! Listen to Latest SolderSmoke

A Great Morning on the Old Military Radio Net: AB9MQ's Central Electronics 20A, W3EMD's Dynamotor, WU2D
I usually try to listen in on the Old Military Radio Net on Saturday mornings (3885 kc). Lately I listen with my Mate for the Mighty Midget receiver.
This morning's session was especially good. For me the highlight was when Masa AB9MQ called in from Normal, Illinois using his Central Electronics 20A (see below). That was one of the earliest SSB rigs. A phasing rig, it also ran AM (which was what Masa was using this morning). He had it paired up with a Central Electronics 458 VFO. You folks really need to check out Masa's QRZ.com page:
Buzz W3EMD called in from Rhinebeck, NY. I could hear his dynamotor in the background. Buzz said hello to Masa in Japanese. FB.
Always great to hear Mike WU2D.

W2EWL's "Cheap and Easy SSB" Rig -- And The LSB/USB Convention Myth
In March 1956 Tony Vitale published in QST an article about a "Cheap and Easy" SSB transmitter that he had built around the VFO in an ARC-5 Command Set transmitter. Vitale added a 9 MHz crystal-controlled oscillator, and around this built a simple phasing generator that produced SSB at 9 MHz. He then made excellent use of the ARC-5's stable 5 - 5.5 MHz VFO. His rig covered both 75 meters and 20 meters. Here is the article:
Because it used the 9 and 5 frequency scheme, over the years many, many hams have come to think that Vitale's rig is the source of the current "LSB below 10 MHz, USB above 10 MHz." This is wrong. An example of this error popped up on YouTube just this week (the video is otherwise excellent):
