Audio: http://soldersmoke.com/soldersmoke264.mp3
Video: https://www.youtube.com/watch?v=_9FcfuqjZxA
We had a small recording glitch at the beginning of this video. But we didn't lose much. We talked about the success of the SolderSmoke Direct Conversion Receiver Project. We talked about the receivers built by Nader Omer ST2NH and Chuck Adams AA7FO. We also gloated a bit about our April 1 post -- you know, the (bogus! ) story about how the Administration is "Supporting Homebrew Radio." Let us know if you were taken in by this, even for just a few seconds.
Pete:
Three CW transmitter projects featuring low parts counts. Good results from Reverse Beacon Network.
The goal in these projects is to raid the junk box and severely limit any new purchases of components. Pete had no idea of the depth of parts he bought and just stashed away. https://www.youtube.com/watch?v=5YLZ7aZpmxQ&t=30s
Bill:
Fixing the 17-12 Rig. Parasitic VHF Oscillations with the SK3050. Good advice from Gemini. Killing NE602s. Fat Finger Syndrome -- hard to work with ICs. Different freq when on transmit -- need for .1 uF cap on pin 8. Worked South Korea -- TRGHS.
Putting the DIGI-TIA back on the air. On 40! And SW listening with the Q-31.
Hard to homebrew for 2 meters. Did some beacon experiments to Puerto Rico on last day in DR.
