Has anyone else had this unexpected behavior happen on a Flex 6500..... Turn on the Flex and the right hand panel was visible but no panadapter. Created the panadapter and it came up on 40 meters. Changed band to 20 meters, and instead of the A vfo going to 20 meters, there was a B vfo created. No problem, just made the B vfo the transmit vfo. Started to transmit on 20 meter SSB and noticed the Acomm 2000a was still on 40 meters. Could not get the Acom 2000a to follow me to 20 meters. On a hunch, changed antenna back to 40 meters and SWR was normal. For some stange reason, the Flex was transmitting on the 40 meter A vfo instead of the 20 meter B vfo (which was the designated XMT vfo). Finally had to close out SSDR and the problem went away. Just wanted to alert the programmers about this stange behavior. Have not seen this happen in 7 weeks of using the 6500, and it may never happen again.
