Batboard

I have UHF GM300's interfaced with a repeater controller and an FT2400 in a remote base configuration. I was getting tinny and hollow audio reports. The 551 jumper in my Rx is set at position B for de-emphasized audio and I am using pin 11 on the 16 pin connector. I am not overdriving. Upon closer inspection of the Rx codeplug; I noticed that signalling was activated. After I disabled this function, it seems that my audio is more natural sounding. Does this feature alter the freq response of the Rx audio?

signaling is done before or after or both but not during so that shouldn't effect the audio you hear.

Victor, make sure you have a coupling capacitor on pin 11 to isolate any DC on the radio or controller ect;. That can make the RX audio sound really bad.

Same for the Mic line going into the radio, 2.2uf + side to the radio IS required.
