I am having a problem with the audio coming from my remote base receiver. I am using a LINKR2A controller. I originally used the de- emphasis jumper setting, but it sounded too treble, so went back to the broader spectrum setting.
The problem is that I have to take the audio directly off of the remote receiver's discriminator, rather than using filtered audio. I currently inject audio from the ICS controller to the exciter on pin 11 of the Squelch Gate card, which is a filtered input. However, when RX audio from remote receiver has PL superimposed on it, it still interferes with the repeater's talkback PL. It looks like I may have to build an RC filter of my own to clip off the PL before it gets to the controller. Does anyone have a suggestion as to a better place to inject the audio?
