[Amps] Harris RF-110A Blower Noise Silencer

[Edward Gable]

Why do you have the Amp so close to the operating position ?  There are no 
needed operator controls unless you want to turn it on and off !!  I put 
mine in the furnace room 20 feet away and remoted everything.  I admit the 
remote bandswitching is a bit messy if you don't have a matching exciter 
with the correct band coding.  If you just want to select a few ham bands 
you can home brew an interface.
