My very first ham radio receiver was a Heathkit AR-3, five tubes for $29.95.
It was sort of a clock radio without the clock, and without a cabinet either
since that was IIRC $5 extra. I think 40 meters had a calibration at 7.0
and another at 7.5. Drifted so bad I had to keep one hand on the bandspread
knob while I was sending so I could keep it from wandering off up the band!
Forget 15 meters--the calibration went from 20 to 25 MHz and my DX-40 tore
up the 21 MHz IF of the TV set, so that band was off limits anyway...
God I'm glad times have changed!

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>
