This is a further update to my post from yesterday on the receive antenna being locked in the loop input mode. The problem occurs on all bands. I have completed a hard reset on the 6700 to clear the problem but it will reoccur on any band where a loop input is selected. Once selected, it is not possible to return the receiver input to the selected transmit antenna. The only way to clear the problem is to do a hard reset and reload the profiles. The problem occurs when either of my two PC's are controlling the 6700. When I am controlling the radio with the Maestro, all is OK. I am running v1.9.13 of SmartSDR for Windows.
I first discovered the issue on 80M as I frequently use a loop receiving antenna and originally thought the problem was limited to 80M. Further investigation indicates that the problem is not limited to any one band. Are others experiencing the same issue?
