[HBR] Mixer questions and other tech questions..

[DW Holtman]

Ian,

Thank you for the great link. This will give me lots of information to mull 
over for a while. I have built the power supply and audio amps, but have 
left the IF/detector for last. I'm building it in sections, testing each 
section before putting it in a chassis.

Thank you again,
DW Holtman
