Steve,

 

I have had the same problem multiple times; I am glad to hear someone else has the same problem. People I am talking to say to take the clothespin off of my nose. In the transmit monitor I can hear thin audio. My problem is that I don’t know how to replicate the distorted audio problem. A power off reset fixes it every time when it shows up. I have been experiencing this problem over many firmware downloads. I suspect there is a root problem that is rare that stems back to the original firmware. I have serial number 508 if that helps.

I have engaged Elecraft help [Gary] but I am waiting for the next instance of the problem. I don’t operate SSB very often so it may be a while before it happens again. For the record Lyle asked that next time it happens to change frequency or change transmit audio equalization to force a new set up of transmit audio chain. Since I received these instructions nothing has happened on my end so I am still waiting.

 

The fact that you are changing bands and the problem stays is an important input. Please keep reporting this issue and I will too when it happens again.
