I respect that this could be whipped up.
But I wanted to take advantage of the user community to see if there were slick products out there. -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Ed Cole Sent: Sunday, July 24, 2022 1:21 PM To: [email protected] Subject: Re: [Elecraft] switchbox KX3 to signalink/mike+headphones I made something similar: I wanted to breakout the mic PTT line from my IC9700 to control a sequencer (which was already wired to control preamps, TR relays and amplifier PTT's). I found 8-pin connectors on Amazon that would mate to the IC9700 mic jack, used RG-174 for shielded cable for the mic audio jumper inside a small aluminum box and used cat-5e for mic cable jumper from radio to switch box and added a clamp-on ferrite bead at the radio end (for ac hum/noise rejection). I used 4-pin mic connectors to route the PTT to/from the sequencer (and using more cat-5e for that jumper). I added a toggle switch to defeat radio PTT if I was running my K3 with the sequencer to avoid accidental keying of the IC9700 by the sequencer. http://www.kl7uw.com/IC9700_Hints&Measurements.htm For interfacing KX3 mic/signal link, you will need a four conductor mini phone jack to mate into the radio. They can be found with a little searching. I made a computer interface for my KX3 using a West Mountain Rigblaster Nohmic: http://www.kl7uw.com/KX3_Computer_Interface.htm These are NOT hard to do projects.
