Hi Gordon,
I need to update that thread.? Correcting the shielding helped, but the issue was a bad 50db tap connection.? The home brew tap developed an open connection for the ground on the BNC meter point.?
The sbitx uses a BNC antenna connection.? I assume that the Icom 718 has a UHF SO239.? Could it be the adapter?
