I have a few questions on cabling. I will be cabling together the KPA500/K3/P3. I got the KPAK3AUX cable set 9-pin Serial cable. Does the serial cable from the PC go first to the P3 or KPA500? 15-pin cable. I plan on putting the included gender changer (key line interupter) on the K3. Then the Y-cable. From there it will go to the KPA500 and the existing 15-pin acc cable. Any issues with putting the gender changer right on the K3? This seems to be the only way you can tighten the screws on all the cables. K3 Key Out Presently I have a cable running from the K3 Key Out to the N8LP SteppIR Tuning Relay, then on to the Acom 2000A. I have added a pair of 12V A/B switches. One in the shack to select the output from the K3 to either the Acom or KPA500 inputs. In the basement where I have the Acom I have the second A/B switch to select the output of either the Acom or KPA500. This way in the shack I have a toggle switch to select either amp. On the output of the N8LP SteppIR Tuning Relay I plan on using a "T" for tying together the key line for the KPA500 and Acom. My question - Do I need series isolation diodes to select which amp for keying? Any issues? Tnx for any feedback. If I missed any of this in the manuals, I apologize up front. 73, N2TK, Tony ______________________________________________________________ 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
