Hello Gary, Lets check the easy stuff first. On the back panel are the jumpers on the correct terminals. RF gain jumper on 1 - 2, AGC jumper on 3 - 4, Line Audio jumper on 11 - 12, and Diode Load jumper on 14 - 15????? With a speaker connected to Local Audio 6 & 7 there should be audio. Regards, Craig
