Hi Elecrafters !!!
I finally did my K2 universal DATA port. I put the schematic on my
website...

I say «universal» because I also add audio transformer to keep ground
loop away and a trimmer to the input, so you will be able to keep mic
preamp setting used in SSB mode. When using RTTY mode with the K2, it
already bypass SSB compressor setting. So that way, you can now
virutally connect anything to the DATA port.... TNC, NUE-PSK modem,
computer sound card..... It will act like the DATA port of a Yaesu
FT-817 familly.
I also add another connector for futur project..... an external VFO
dial with keypad.
Stay tuned !!!
Best 73
