When using a signalink usb for tx/rx switchingvarAC will not allow you to log the qso because the frequency is not entered BUT you can’t enter it in the box as it doesn’t recognise a manually entered frequency.
from V3.2.1 you can set frequency without omnirig. you can now log QSOs correctly. Closing the bug
You can select the band from the drop down menu on the band box.
Doesn't it work ?
