[Elecraft] Re: N6XI NAQP RTTY July, 2007 with K3

[Jeff Stai]

hi Wayne - thanks for the reply! I understand now what you're dealing with... the GPIO sounds like a 
cool way to get several different interfaces off the back panel of the radio.

I guess I just joined the ranks of those who just can't wait for their K3 and then spew all over the 
reflector about it... I blame the fact I had to shlep a 70 pound radio one more time to the station 
I guest-operated at yesterday...;)

thanks, and apologies to everyone! - jeff wk6i

ps: one each transistor and resistor in a DB9 shell is in my skill set, two each are right out!
