[Elecraft] K2 Fixed Audio Output Board

[Dave Van Wallaghen]

Hello all,

Over the past few months, I have received numerous requests from my K2 
customers to provide a fixed level audio output (independent of the AF 
gain control) for using the K2 with the various digital modes. I took 
the design set forth by Don Wilhelm, W3FPR and Tom Hammond, N0SS (SK) 
and put together kits with a couple of my adaptations.

This is a full kit with everything needed to build and install the Fixed 
Audio Output Board complete with wire and speaker cable to connect the 
board to your K2. An RCA jack is provided to mount to the rear panel of 
the K2 for the audio output.

Having a fixed level audio output makes using the K2 for digital mode 
operations much more convenient in that audio levels can be set once at 
the soundcard input and eliminates the tweaking of the AF Gain control 
to get the correct level each time used. It also allows the user to 
monitor the K2 audio during operation.

Full details about the kits and ordering are available on my website:

For those not interested in a full kit version, the total bill of 
materials with vendors is listed in my installation instructions pdf 
file. I ordered enough parts to make up 25 kits. I have about 20 left. 
If I receive more interest than the 20 I have left, I will certainly 
order more inventory.

Dave, W8FGU
