Hi Tom. If you already have the KPA100, look on the rear panel and you will see an RCA jack marked "PA KEY OUT" between the ground connection and the power connector - this will allow you to key your external amplifier directly - but only if your amplifier has a positive voltage for its keying line. If your amplifier uses a negative voltage keying circuit (like the Collins 30L-1 and some others) you will need to construct an external circuit to key the amp. 73 --don n4hh K2/100 #2028
