[ARC5] BC-453 drift test

[DSP3]

I certainly concur.  I run 4 receivers and use a nominal B+ of about 
160v.  Current measures about 40ma, max. There is no measurable drop in 
anything except perhaps total audio output power, certainly not 
sensitivity or BFO operation. The R-25A is used as a tunable IF for the 
ARC-2 and, as performed by others, find drift after a nominal worm-up 
time to be very, very low.  Granted, digital usage is not a 
consideration at this QTH.  That said, I also run B+ on BC-348 
receivers, et al, at about 180v with, again, no degradation.
