Hi
Oddly enough I also used a BC-453 to copy CW on the same bands. I
suspect that more than a few of them were used on B-17's for the same
purpose. The one I had came by way of the RCAF and Fair radio. Darn
near new in box condition.
Back then I found it odd that there was no matching ARC-5 series
transmitter for the same band. That situation makes a bit more sense
now.
Sure would be nice to still be able to pick up new BC-453's for $20 and
the tuning knob for another $3. Time marches on ...
Take Care!
