It might work to split it into two problems. MFJ makes some boxes to switch microphones and rigs, 2:1, 1:2, and 2:2. Maybe more.
https://mfjenterprises.com/products/mfj-1260 <https://mfjenterprises.com/products/mfj-1260> There are also simple 2- and 4-channel mixers that would do it. I use a simple splitter for the headphones and drive everything all the time. https://smile.amazon.com/Belkin-RockStar-5-Jack-Headphone-Splitter/dp/B00904WS2K/ <https://smile.amazon.com/Belkin-RockStar-5-Jack-Headphone-Splitter/dp/B00904WS2K/> This is a headphone distribution amp (build with op-amps), so you can adjust gain for each output. $29. https://smile.amazon.com/Behringer-HA400-Ultra-Compact-4-Channel-Headphone/dp/B000KIPT30/ <https://smile.amazon.com/Behringer-HA400-Ultra-Compact-4-Channel-Headphone/dp/B000KIPT30/> Rigblaster makes some nice stuff, though I’m not that familiar with it. I think they have boxes that would replace the Signalink and do the switching. http://www.westmountainradio.com/rigblaster.php <http://www.westmountainradio.com/rigblaster.php> wunder Walter Underwood K6WRU https://observer.wunderwood.org <https://observer.wunderwood.org/> (my blog) > On Jul 24, 2022, at 3:52 PM, <[email protected]> <[email protected]> wrote: > > > 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).
