Don, does the "Y" connector Elecraft sells work for this? I have on order a KAT500 and a KPA500. I can't quite figure out what the KPAK3AUX does, but will that address the problem?
Here is the long-term plan. I want to operate this station (in Maryland) remotely from our home in Key West. I will get a K3/0 when the mini comes out, and the RemoteRig gear. I will not need the P3 hooked up for that, so maybe that frees up the needed pathway. But while I am in MD, I do need the P3. I want the KRC2 only for antenna switching. However, the audible feedback was the way I was going to be sure the antennas actually switched --- by monitoring the station remotely (including the readout of the rotor) using a webcam and mike. . If that is the only reason to keep a PC running, I can give that up. Of course, I can probably give up the Navigator (only when operating remotely) if I am getting audio in/out using RemoteRig. So my questions are: Other than the audible cues, what do I give up by loading the KRC2 firmware vice the KRCACC firmware? I really only must have antenna switching. Will the Y cable from Elecraft work with a KRC2 (not ACC) and a P3 and a Navigator? What does the KPAK3AUX do for my eventual station (full remotely controlled K-Line)? Does the Y cable that comes with that fit my needs? Thanks so much for your help. 73 de Brian W3BW *Brian F.
