I'm trying to get a pair of CM140's working as a repeater, but having problems with the audio quality.
RX audio is from Pin 11 TX audio is into pin 2 (mic) via a 10k pot to set the level. RSS options for Pre and De-emphasis produce either very "toppy" audio with a slight hiss, or overly bassy. What settings do people normally use for the emphasis? What audio path between the radios is normally used? Is it normal to use pin 2 (mic) for the TX audio (seems standard on RICK and Zetron diagrams), or is pin 5 (flat) used? Thanks. Jim
