I am running a 6300 with the current software version 1.3.0 although the problem existed since I purchased the radio in Dayton. Example - one band is set for 6m and the 2nd band for 10m. Ant1 is selected for rx and tx with one slice on each band and everything works fine. When I choose Ant2 or Xvtr for rx on either of the bands, the other band also changes to Ant2 or Xvtr on rx. The tx selection works independently with one selection of Ant1, Ant2, or Xvtr not affecting the other band. Has anyone else experienced this problem?
