Horst, Have you just connected your antenna to the MV62, or is the=20
antenna tuned with a loading coil? You will not receive many weak=20
signals until the antenna is properly tuned. It is likely that the=20
local computer QRM will appear much weaker when you have stronger=20
signals down the antenna.
