[ARC5] Poor Mans A4

[Robert Nickels]

One of my main interests is vintage sideband, and in looking through the 
folder of notes that came with a Central Electronics 10A exciter today I 
came across something interesting that I hadn't seen before.    It's a 
single dog-eared photocopied sheet but still readable - and describes 
modifications to a BC-453 for improved AVC, product detector, and high 
level audio output.   It's all common circuitry but I thought it might 
be of interest, so I scanned it and posted a copy here:

As the notes indicate, this would be done in addition to the standard 
mods.  I don't intend to re-ignite the flame war over modifying mil 
surplus gear but if someone has a BC-453 Q5er, I'll bet this would make 
it pretty sweet on SSB.  But maybe not quite a 75A4 ;-)
