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.

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 73, Don W3FPR On 7/18/2012 1:37 PM, Chris Kimball wrote: > I'm looking into digital modes such as Contestia or Olivia.
