[Boatanchors] [ARC5] Unusual BC-221

[Sudipta Ghose]

Hi Gang!
So far as the Calibration Book is concerned - I handled several BC-221
during late 70s -early 80s period as I converted them for fellow radio
aficionados who were mad mainly with BC DXing. I found that many
calibration books had corrected entries pages after pages. I always
wondered who took such pains and where? Were these units sent back to the
manufacturers or the GIs did this in their unit radio rooms?
