Works great! In fact, I call mine the KPSK2 since I can't figure out how to use the MH-2. I've brought Audio Out to an unused mic pin, and have a Laptop-K2 cable that handles all tasks. Laptop has LineIn, Spk, and PTT (Serial port, with transistor and a couple resistors), K2 has only the 8-pin on the front. Tasty! Dan / WG4S / K2 #2456 <snip> not for SSB but for PSK31 </snip>
