I purchased a new PCR-1000 last summer and have used it only AM and FM with great success with TalkPCR. A few weeks ago I tried to use SSB (for the first time) and it didn't function. no audio. As soon as I switch modes using the original Icom supplied software from AM or FM to SSB or CW no audio. Anyone else have similar experiences before I send this off to Icom? Craig W9CLA
