[Elecraft] Going 2014 with my K2

[Don Wilhelm]

Phil,

On the digital modes setup for the K2, the only update was to the Fixed 
Audio Output - same circuit, but the board was redesigned to allow all 
the components to lay flat on the board so it could be mounted between 
the Front Panel and the Control Board.  My memory is fuzzy about when 
that came out, but I believe it was greater than 5 years ago, so you 
likely have the latest.

I am still using the Digital Mode switchbox that is on my website 
www.w3fpr.com and it changes from digital modes to microphone (the mic 
still plugs into the switchbox.  The only change I have done to it is 
add a capacitor between the switch and the audio output transformer to 
block the DC from the microphone bias resistor which would flow through 
the transformer if the capacitor were not present - I use the Elecraft 
MH2 microphone, so it needs the bias resistor.

73,
Don W3FPR
