Hi, [ Reposting in seperate thread ]
For the 4-pin mic pinout for the MH-3 microphone, it is listed that the PTT line also carries logic for UP and DOWN keys.
As I want to interface using a Heil Traveller headset, which has the UP and DOWN key signals on a seperate line (8-pin round standard), how are the logics defined for this pin (first ring on the 4-pin jack) on the Kx3 and MH-3, respectively ?
Would it be possible to ask for a schematic ? 73' Brian OZ2BRN Kx3 # 1118, K2 # 6936 ______________________________________________________________ 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
