Ian, Just make sure the cable conforms to the Elecraft manual pin outs. Some (many) VGA cables will connect the coax shields together at one end or even both ends and some tie those to the ground pin and/or shell. I made my first cable since I had 15 conductor ribbon cable & the connectors w/shells. For the second cable, I found a VGA cable in my junk box that had continuity on all the pins with none of them connected together or to either shell. I then removed the pins on one connector (broke them off) to confirm to the manual but I don't remember which ones. My K-Line works fine; especially since I upgraded to VFO "follow"! 73 George AI4VZ

Elecraft does some different things with their cables than you might find if you bought the same cable from other sources. Hope this helps. -- Ian Ian Kahn, KM4IK Roswell, GA EM74ua km4ik....@gmail.com K3 #281, P3 #688, KPA500 #1468 HRD v5.x/6.0 Test Team -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of tom armour Sent: Sunday, February 16, 2014 11:54 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 to KAT500 So I ordered my K3 after this discussion and decided not to get the AUX cable. Now subsequently there is new firmware that makes me want the AUX cable (I would have got it from Elecraft if I had know of the new firmware). If I order it from Elecraft it now costs ~$46 including shipping and waiting a week to get it. I can get this cable locally: http://www.qvs.com/specs/CC320M1-xx_S.jpg Will that work for the AUX cable?
