Junkyard Warz Novelty Transmitter by W9QZ

Several month ago I found a great, probably most artistic Glowbugs Radio homebrewer in the WEB - Rick Weber, W9QZ. I've been very impressed, downloaded some beautiful photos of those stylish Rick's HAM-Radio artefacts and, naturally, forget to check this page again - it was my mistake. Take this:Rick:"Junkyard Warz Novelty Project. This is...

My notes in bold after each section.Testing audio transformers©...

RF Amp

Most of my 30s vintage transmitters are in the 10-20 watt range. It would be fun to have a little more power, especially with my 10 watt Meissner Signal Shifter / VFO. According to the specs two Taylor TZ20s in push-pull can be driven with 5 watts to about 110 watts input or 85 watt output. This sounds like what I'm looking for.As usual any...

M1KTA shack almost finished reorganisation

Anyway the roof is done and the internal reorganise is 50% done now so should be back melting solder shortly.The Yaesu FT897D will be retired (not going to sell as useful rig for IOTA trips)...

Big Nick and the Cydecos - Glowbugs Radio Hide-And-Seek

Today I decided to become (at very last) a real blogger and to invite some celebrities as a trendy stuff. But as it turned out, neither Madonna nor Britney Spears did not make the tube radios, Arnold Schwarzenegger is possible and would do, but too busy at work, and Michael Jackson .. Okay, let's not about sad - the result of my quest was...

6P3 (6П3) Beam Power Tetrode

6L6 vacuum tube has been introduced by Radio Corporation of America in July 1936 and since 1937 it began to be produced in the USSR on equipment provided by RCA. For the first time it was usual metal 6L6 , but later was chosen glass bulb design in order to avoid overheating, so just before the WWII tube factories started to produce 6P3 (6П3)...

1929 and 1930 Stations

Lots of times questions get asked about what sort of rig to put on the air as a 1929 station. What were hams really using? Do the back page ads in QST really reflect what was on the air?As I went through my old issues of the AWA OTB/Journal I found Bruce Kelley's comments on 1929 equipment in the May 1994 issue. He summarized 1929 and 1930 QSL card information from W1NE. He saw that Hartley oscillators and the 210 dominated the...
