I'm experiencing what I assume is the I and Q buffers losing sync. Once this happens quadrature is lost and a DSB and a delayed DSB audio signal is transmitted instead of SSB. It has happened in all the previews and has been causing problems with interference to other stations.
It seems to happen when switching from RX to TX. Since I use LSB 99% of the time I don't know if it happens in all modes. The only way I can detect this has happened is when I switch back to RX and hear an echo in the receive audio. Unless of course someone complains that I'm interfering on the USB freq. Toggling the 'On/Standby' is the only way I've found to regain sync. This happens about three times an hour during a QSO. I've tried different buffer sizes, but I can't find any correlation. Any thoughts? 73, k2ox
