Or a composite video A/B switch. I have been using a Radio Shack composite/S-Video one in two out Stereo audio and video switch to delegate amplifier key lines, footswitch and Paddles between my primary K3 and my secondary TS570 for a few years now.
The S-Video lines switch the paddles between each radio's Microkeyer, while the video and audio RCA cables switch the footswitch send to the Microkeyers and the key lines from the rigs to the amplifier. Snazzy thing, a sloping front panel in silver and gray plastic with big rectangular hard to miss delegation buttons that came with custom labels. I even have a spare set of RCA jacks that might be pressed into service for something else, like big fat red "this radio is enabled" LED lamps... Well, maybe not :) Cost a total of I think $4. I have seen other similar things at WalMart and Target. -lu-W4LT K3 # 3192 Message: 9 Date: Wed, 16 Feb 2011 16:52:50 -0500 From: "Joe Subich, W4TV" <li...@subich.com> Subject: Re: [Elecraft] K3 keying an amplifier To: elecraft@mailman.qth.net Message-ID: <4d5c4732.1030...@subich.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed The same thing can be accomplished with any 2 x 2 or 2 x 4 audio switcher - left/right become PTT and ALC. Radio Shack and most consumer electronics stores have a reasonable selection of A/V switches generally for less than the cost of a case, switch and the connectors. 73, ...
