K3 - N1MM/MMTTY/FSK/CW Interface/Procedure for

[Mike K4PI]

I use a board sold by W3YY for interfacing RTTY/PTT/CW.  I also built into the box housing a 12 V fan out for P3/PR6 and AUX and plug the main into the K3 12 V ACC.  Also D connector for the PR6 connection and another D connector for band out data to a DX Eng antenna switch.  Made a nice package and makes jumping modes quick CW/RTTY/PSK/ quick.  I am really pleased with the W3YY board using optical isolators.  73 Mike K4PI
