Anyone out there have an SX-111. I have one and have been using it on
the air however, I recently installed an outboard preamp (Solid
state) that helps the receiver quite a bit.
I installed the preamp because the receiver seems so deaf from 20
meters and up. 80 and 40 are fine. I did a complete tune up
including front end and both IF's. I checked the tubes and all seem
OK. Is it possible the front end of this receiver is very good on 80
and 40 and stinks on the higher bands?
