When using UT you will not be able to listen to anything. You can turn up the audio however you will only hear control channel so turn it down. UT needs control channel audio from discriminator tap to work properly. BTW, make sure you couple the audio from the discriminator output to the cable your are using to either connect to the jack you are installing on the back of the scanner or the cable that will just come out the back of the scanner. (like I did )KE5HOB said:If I decide to tap my Pro-433 and use UniTrunker, will I still be able to get audio from my scanner, or can I only listen to the radio when not using UniTrunker? I know its a n00b question, but I guess I am a n00b!
