Looking for some advice. I am using an Icom A5 transceiver mounted on the panel. It has the ni-cad batter installed as well as connected to the ships power. It is connected to a Comant CI-122 antenna via RG400 cable. It also runs through a Sigtronics SPO-22N intercom. When I am in the vicinity of broadcast radio antennas or at a lower altitude over a city with broadcast antennas, I get a constant, fairly loud garbeled bleedover from their broadcast. Adjusting squelch doesn't help much. I can still transmit and receive ATC ok as it blanks out the bleedover. I'm curious if it's just a handheld transceiver issue? I've been looking at installing one of the smaller radios, ie;Becker, Microair, MGL, etc.
Anyone have any ideas?
