I got 2 audio cables today and have been working on Unitrunker. My Queston is what setting does Unitrunker have to be on to recieve info From one of the UCAN sites? It does fine picking up the Questar Site and all its info and even the 952MHZ site which it says its a ProVoice site. But on Ucan No Signal. should I switch it from Motorola to hexidecimal or decimal?
