Tks for your reply, Bob. I've got both the Squelch/RF-Gain menu option (#80) set for RF Gain use. BTW, even if the Squelch was the culprit, the audio would go completely silent once the signal (or noise floor) dropped to the cut off threshold.
When this intermittent symptom appears, there's definitely audio coming from the speaker (or headphones for that matter), but any signal(s) on freq is far reduced for several seconds before slowly returning to normal. The S meter's indicated value?drops and then rises at the same rate.
If the 857 used a mechanical relay for T/R switching like in older rigs, I could easily believe the relay was sticky. Not the case with the 857 of course though.
Tks/73,
