Here's a good one... While testing the latest version of my Anti-VOX board I got reports saying that my SSB signal was "clicky"on VOX. I thought the worst...
After much investigation it turned out to be nothing to do with my board, or the K2 for that matter. Some "Engineer" decided when he designed the MD-100 microphone tone control circuitry to route the PTT line clean through the center of it's analog circuits. The K2 uses the PTT line on VOX for TX/RX changeover. The effect I was getting was the low to high transition at the end of the VOX delay period being coupled into the microphone audio, causing a "click". The solution was simple. I removed the PTT wires where they connect to the main PCB in the microphone base, and reconnected them separately. End of problem. It is possible that other microphones may be similarly afflicted. If anyone wants more detail, please shout. 73 Stewart G3RXQ B.T.W Version 3 of the Anti-VOX is working well. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
