Just installed a Uniden bearcat cmx560 (an all in the handset unit) ran that through ~9ft of coax to my firestik moutn and to my ~4ft firestik classic antenna. hooked up the SWR meter first (of course) and followed its instructions. SWR reading is just above 1. great (seems a bit too good to be true, but whatever) i have set up several CBs in several rigs the same way without issue. here is the issue(s) in this setup when i key the mic (to transmit) the AM/FM radio gets quieter, the volume. the two units are not tied together, other than chassis ground...any ideas? i have not tried to receive a known signal, but all channels i was receiving static unless i changed the squelch to level 2 or 3 (this unit only has 1, 2, or 3 for the squelch, which is frustrating) bad radio ground? bad antenna ground? ideas? tonight i will try sending from one of my rigs to another and see what happens.
