The IC-R8600 only supports changing antennas below 30 MHz and due to the way wfview works, you need to be on an amateur band below 30 MHz for it to be enabled. You can always move to an amateur band and change the antenna. Then move back to your operating frequency.
No big deal, but for a future rev., could it be made such that you can simply change
the ant input (for <30 MHz) “anywhere” ? Not just when monitoring a Ham band.
