I've restored many HW-100s and HW-101s over the years.
The linearity is not all that great. If you're only
off by 5 KHz at the "500" end, that's fine. Use the
crystal calibrator and dial correction to line it up
when you're in that end of the band.

In article Dwjee.26170$lZ.8166@trnddc04, says...

I can get the VFO dial to be right on at both ends but up to 5khz (one
division) off at mid dial
or right from 0 to 400 and 5k off at the 500 end.
I found a reccomendation about the using the lower coil peak point and i
t
makes no difference.
How much dial accuracy can I expect fron this thing?
Any idea what to try to make it better?

Another question
I'm not sure whether to adjust the points for zero beat or peak meter
deflection.
