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:
https://www.w8fgu.com/k2_fixedaudio.html
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.
73,
Dave, W8FGU
