- FeepingCreature 7y agoThat is correct. (Though usually 3.5mm.)
- qdot76367 7y agoThe only places we usually see RS-232 (either swing or TTL) over TRS is estim, funny enough.
- jrockway 7y agoMy Elecraft KX3 radio's computer link cable is almost the same RS-232 over TRS pinout that the ET312 uses. I think one pin is different, though, and had to build a sort of crossover cable.
- qdot76367 7y agoOk, since you're familiar with the ET-312... You know we reversed the ET-312 to the circuit level, right? :) https://github.com/buttshock/mk312-bt https://github.com/buttshock/mk312-bt

- jrockway 7y agoYeah I've looked at that a number of times. I always thought it was cute that they went to so much effort to scrape the part numbers off the ICs.
