[ICOM] ALC interconnect

[David J. Ring, Jr.]

A friend of mine asked me how he could hook up an old amplifier to his IC756 
(non PRO version) as he knew I had ICOM radios.

He is using a National NCL-2000 tabletop amp, and there is a RCA jack 
providing ALC voltage.  He has the ICOM manual but not the manual for the 
amplifier.

I will go and measure the voltage and polarity but I would assume it is 
about 0 to 3 volts negative.

How does he hook up the units up?  Is ALC "self-adjusing" or is there a 
proceedure needed to adjust the threshold?

Thanks -
