Thanks Ofer, good to know it's not just me without heading data.
I'll put that problem further down my list for the moment!
Some progress ...
Today I moved the VHF Antenna cable which was connected to the VHF radio, to the FA50.
Now, I am transmitting successfully, as well as receiving.
So, now I need to find out where is the bad connection to the antenna.
I note there are 4 VHF antennas, 2 on each mast.
Why so many?
