The NO SSB audio also happened to me on one of my K3s. All other modes were fine but and after a few minutes of experimenting I found out that I could get SSB RX but only by opening up the Width beyond the 2.7kHz first filter. As soon as the width was at or below 2.7 the audio was gone. I also checked to see if I could open up other modes - NO. The width setting would not go beyond my second filter which is set to kick in / out at 500 hz. So, I did a "RESTORE CONFIGURATION" from the one that I saved just after loading the new 5.1 firmware. That seems to have fixed it. Not sure why - but it is working. My other K3 is running the same 5.1 firmware and has not had the problem.
Something must have changed, but to my knowledge, I did not do anything. 73, Bruce - N1LN ______________________________________________________________ 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]
