[CQ-Contest] Audio Distribution Unit

[Steve London]

I have an older version of the ART HeadAmp 4. Use it at home, and at 
several multi-op efforts. No RF issues. Great for sharing of audio. On 
my version you need to be careful about the polarity of your 12 volt DC 
supply. It is a standard connector, but + and - are backwards from what 
you would expect.
