Something that has always surprised me is that the K2 has no front panel indication of when it is on transmit. The only way to tell is when there is no audio out of the loudspeaker, or the S meter has no LED's lit. If the AF gain were turned fully down there is no way of knowing. I can put my K2 into transmit by any of the following means:- PTT switch on the mic body, switch on the mic base, key, footswitch, VOX or computer.
I decided to make a clear indication of when the K2 was on transmit. Getting inspiration from various articles on fitting zero beat indicators to a K2, I now have a small red LED that is positioned in line with the RIT and RATE buttons which illuminates on transmit. This was easily done with a small piece of PCB material cut to size, and fixed as per the zero beat PCB's. The miniature LED is wired with a series 1k resistor between front panel board connector J1 pin 4 (/DOT-PTT) and pin 18 (5A). I now feel much happier that I am not accidentally transmitting over someone else's QSO because of a stuck PTT button on the microphone. 73 Stewart G3RXQ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
