"I just ordered the KPA500/KAT500 combo and W2 watt meter for my K3S. Should I use the key line interrupt connected to the W2 watt meter or should I connect the key line interrupt to the KAT500? Do I even need to use key line interrupt with the K line set up?"
Why would it hurt to have multiple ways to inhibit KPA500 keying? I run a Kenwood rig so no AUXBus control but my KPA500 key line passes through my LP-100A and through a SteppIR inhibit circuit. Both can open the key line. In addition my station controller can assert KAT500 key inhibit by serial command. KAT500 key line inhibited is my default condition. I only allow the key line to be enabled if several critical checks have passed. (e.g. KAT500 frequency, KPA500 band selection, Kenwood drive power setting.) I'll do anything I can to avoid being on the list of people who fried their KPA500. I can fix stuff but I'd prefer to chase DX. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
