The osc is not running, period. Just a note on basic superhet practice (for convenience, say the IF is 460): When the radio is set up and aligned correctly, the osc will always track 460 on the high side of the received signal. So whatever station is tuned in, its signal will 'beat', or heterodyne, against the osc, generating the
Intermediate Frequency of 460 khz, which is then sent downstream, amplified and detected.
Um.. what does O.L. stand for?
