Receiver local oscillator tracking.

The multi-gang circuitry and calculations were devised in the 1920's with
the advent of the Superheterodyne Receiver and the 1930's multi-grid
frequency-changer tubes. All had to be extremely tediously worked out with
slide-rules or log tables. Just think what the old boys could have
accomplished had this program then been available.


I wouldn't be surprised if Edwin Armstrong could do it in his head.
