Put your finger on the end of the INPUT cable and transmit. See if you get hum. I found that the chokes on my input lines are bad... dunno why but evidently some radios have bad chokes.

I'm trying to help a friend setting up his K3 for PSK with a Signal link USB and HRD. It goes into transmit but the output power is zero. If I turn the USB's tx gain all the way up, I can hear some weak audio from the K3's speaker when the ptt keys it to TX. The mic+LIN is ON. What am I missing?. -- Dick - K4XU ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
