I remember 3023.5, except I can't recall what it was for. Was it a
common HF tower frequency even though most of the equppage was VHF by
then? Perhaps you had a VHF receiver, but only an HF transmitter?
From the day I started the aircraft I flew either had no radios or
they had VHF transceivers (perhaps with only a few transmit crystals
and an analog receiver turner.) I remember my first IFR set well, the
Narco Omnigator. Did a lot of ATCS en route communications with that
equipment.


3023.5 KHz is 3.0235 MHz, and I doubt this is what you remember. 3023.5 Hz
is possible, since this is in the HF band, being just over 3 KHz.
MegaHertz band receivers weren't in general use in the 50's.



Like I said, the equipment I used had the same basic VHF comm frequencies we
use today, except there were a maximum of 90 channels (100 KC spacing?). Most
of the equipment I used had 4 to 27 transmitting crystals and a continuous
tuning receiver. Those were around in late 1956, for sure.

I only remember seeing 3023.5 on the charts, and I presume, as you say, it was
Cycles, not KiloCycles (no Ms. Hertz back then ;-)
