[ARC5] 4th Receiver Drift Test from KE6F Hallicrafters S38B

[Rich Post]

When visiting the Lowell Observatory in Flagstaff, AZ a few year ago, I
noticed a lone S-38 sitting in the room.  I wondered why it was there and
then it dawned on me.  It was a clock accurate to the second, ticking away
WWV in the dark night, no light needed.  Apparently it was good enough to
accurately stay tuned to WWV.  Which S-38 model?  I didn't check but it was
a letter version, so A, B, or C since it did not have the extra red slide
switch of the original no-letter version.
