[Lowfer] frequency counter calibration

[Douglas D. Williams]

You just have to be STRONG, like HULK! ;-)

Good idea on the NiMH.

IMO, Optoelectronics would have been better off just including a
battery compartment for users to replace the four cells with discount
store alkaline batteries. Then they wouldn't even have had to include
the Wall Wart charging system.

But the whole thing is an antique now anyway.
