[Elecraft] Digital modes interface for K2 - recommendations sought.

[Mike Heitmann]

I can vouch for and highly recommend the circuit on Don's website.  I built one 
several years ago and  installed it in my K2. I wired it to unused pins in the 
mic connector so  I only had one cable to deal with when 
connecting/disconnecting. I've  made many PSK and RTTY contacts using it.

I was fortunate enough to get one of the last PC boards, but as Don says, it 
would be a simple matter to build it on perf board or "dead bug" style.

Works great!

Chris,

Not a full solution, but you may want to look at the K2 Fixed Audio 
Output on my website www.w3fpr.com.  There are no boards left and no 
kits available, but the circuit is simple to wire on perfboard - it is 
all audio frequencies and nothing is critical - just a simple LM386 
audio amplifier
