[VHFcontesting] 903 Motorola Amp

[Dana Rawding]

Best place to look for mod info is here: http://www.vhfsouth.org/ 
tutorials/902.htm

Bias is set by the yellow wire.  If you have the 300W version you can  
pick it up from second pin from the right on the header where it goes  
into the rf compartment.  I used a Omron G5V-5 relay set up the same  
way as the above web page.
