I don't know what an official factory job looks like, but it looks
pretty well done.
The frequencies printed on the crystals seem to be 22.8 and 24.5 MC?
They look
like WW2-surplus tank radio crystals, and I try to work out
how 455kc gozinta those and end up with multipliers like 54. Does
that ring a bell? 54 = 3*3*3*2, and 24.5/54 = 453.7kc.
I know that 50's/60's era ARRL handbook BFO crystal articles had a table
or
formula relating tank radio crystal channels to IF-like frequencies.
> This guys feedback reminds me of radio mart.
Hard to tell. Other guys have drawn a similar conclusion from other
auctions
by this guy (esp the red velvet in some other pics), but I don't see all
of
radio mart's stupid boilerplate. Superlatives in the description are
similar though.
