I am attempting to operate PSK31 on my K2. I am using a BuxCom Rascal interface, with a cable from "external speaker" for audio into the computer, and a cable to the mic input using both the audio in and PTT lines with a common ground.
I am able to receive properly, and the PTT works correctly. However, the audio input is not working correctly. There is little or no output from the K2 (as seen on a wattmeter) no matter what the audio input level is from the computer sound card, but if the signal is monitored on another reveiver there is a very noisy, pulsing tone that does NOT change with raising and lowering the audio input level from the computer. Since I have been using the computer and the interface with other rigs, I believe the fault is not with these parts. I have also confirmed that the mic connector is wired correctly. I have set the K2 up to use the Heil Proset headset, which means that I have placed the appropriate resistor between pins 6 and 1 on the front panel mic connector. My suspicion is that the voltage supplied by that resistor may be causing the problem. Since I will be using the K2 with the Proset most of the time, I do not wisk to remove the resistor. Anyone have any experience with this or any suggestions? Thanks. 73, Larry WA3ELQ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
