I would like to configure an ICOM IC-2820 with dual receive. It would seem there may be a couple of ways to accomplish this task - looking for advice:
Option 1 - Allow independent front AF per Left/Right
Configure “Audio dual-rx” to YES
Build custom 3.5mm cables:
Cable #1: IC-2820 to Radio-RRC
SP-1 TIP & Ground to Radio-RRC Speaker TIP & Ground
SP-2 RING & Ground to Radio-RRC Speaker Ring & Ground
Cable #2: Control-RRC
Control-RRC Speaker TIP & Ground to +/- (Left) External Speaker
Control-RRC Speaker RING & Ground to +/- (Right) External Speaker
Option #2 - Use IC-2820 Mixer for “combined” audio
Configure “Audio dual-rx” to YES
Connect 3.5mm stereo plug between Radio-RRC and IC-2820 SP-1
Build custom 3.5mm cable:
Cable #1: Control-RRC
Control-RRC Speaker TIP & Ground to +/- (Left) External Speaker
Control-RRC Speaker RING & Ground to +/- (Right) External Speaker
Questions/Comments - Please!
