[Milsurplus] My "ARC-5" Impressions (long)

[Bruce Gentry]

I have swapped IF  and BFO coils between sets with excellent results, 
the RF coil pack gets more dicey as you go up in frequency. However, 
they have always worked well without re-alignment, and the dial 
calibration was surprisingly close.  Tweaking the oscillator padder and 
trimmer was all that was really needed. The RF amp plate coil usually 
was on peak, and the antenna coil was brought dead on with the front 
panel antenna trimmer.  What fun it was, a couple bushel baskets full 
of  ARC-5s in various stages of disassembly and condition, and a best 
friend to  share it with. Warm winter nights and memories from 1967.
