Moxnix - It's a solid transmission.
On the CB transmissions, I'm hearing some hum in the background.
If I'm not mistaken, Slim planned to take the speaker output of the CB into the AV1-A direct box, which knocks it down to a balanced mic level input. If that is indeed how it's wired, try flipping the ground switch on the AV1-A - the hum might go away.
Thanks for the hard work.
