[Elecraft] HF Digital interface for the K2...

[Ken Alexander]

I have Don's fixed audio mod in my K2 and it works
very well.  It's wired to the front panel mic
connector, which works perfectly when you use the
Tigertronics SL-1+ audio interface.

I spoke to Don about MicroHam's using the audio
available from J5 inside the K2.  He didn't think it
was a good idea, but he can explain why better than I
can.

73,
