"My question is since I do not have the KPA and KTA connected to a K3 (it's a K'Wood TS-480), do I really need the aux cable between the KPA and KTA?"
Aux cable not required and would, to the best of my knowledge, do nothing in your configuration. What you probably can do is have the KPA500 poll the TS-480 with IF, FA, and FB and have the KPA500 and KAT500 listen to the replies. (I only say probably because I assume, but don't know, that the TS-480 supports IF, FA and FB responses. It works for TS-590 and TS-890). Elecraft sell a serial cable for exactly this purpose. Be aware though that KAT500 will only follow VFO A if you use this configuration. KPA500 will follow the TX VFO regardless of whether that is A or B. Sorry, but I have no experience with the power up pin. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
