The stock radios drift about 20 Hz (15 MHz WWV) in the first 10

temperature. I often hear Orions on the air, especially on the TT
Sunday net, and very often they are 20 Hz low in frequency.
Well, I guess you've exposed me as a Luddite!
20 Hz!!!???? Even when running RTTY with 170 Hz shift, I don't recall
worrying about 20 Hz.
When I was a freshly minted Novice, my dad gave me his rig (it gave him
a good reason to get a new rig for himself). The receiver was a
BC-348...and its dial calibration was every 100 kHz--- 7.0, 7.1, etc.
Times change and I guess we worry about stuff because we can. Now if
you'll pardon me, I've got a buggy whip that needs to be polished. <grin>
