Guy, It wasn't me. It was "kcflyers" (call sign unknown) who reported this - I wasn't awake enough when I replied and forgot to include his original message, which demonstrated a lack of understanding about the use of the two VFOs:

If he was somehow making S&P QSOs while this was happening, he must have been transmitting simultaneously on both frequencies, which certainly would be an indication of serious problems inside the radio. I suspect he was not making QSOs and just had Split turned on without being aware of it. 73, Rich VE3KI On 07/03/2011 12:57 PM, Guy Olinger K2AV wrote: > My question is whether or not you were making contacts S&P during the > time that this was occurring.
