Thanks Adrian for you advice. I did change the ACC2 IO setting to LO=PTT. The KX3 still will not key the KPA500 when I press the mic button. The KX3 goes into transmit but not the KPA500. I have the center wire from the KPA500 PA Key connected to the tip of the 2.5mm plug going into the KX3. If I reverse the lead on the cable (from the PA Key to the ACC2IO) the KPA500 does go into transmit without me keying the KX3. That is where I was before, I have to put the KPA500 into standby to receive and then put it into operate when I want to transmit. For your information I do use my KPA500 with my K3 and it works perfectly. I did discount the custom cable between the K3 and KPA500 when I connected my KX3 to the KPA500.
Is there any setting on the KPA500 menu that I need to change? Any ideas?
Thanks

I doing wrong? (incidentally >the KX3 will drive the KPA500 to almost 200
watts output).
ACC2 IO setting > LO=PTT (input; apply 0 V or ground to
activate PTT)
