[Hammarlund] drift of receiver HF oscilator

[Ken Hickman]

Hi John & RJ Mattson,

Is my face red! Guess I've been away from radio theory too long.
Of course the front end oscillator had to be variable and arranged to
track with the incoming signals to give a fixed intermediate frequency!
Wow! Next time I'd better to check if I am fully awake!
Take care,

Ken   N5CM
