[HBR] BC-453, other than IF transformers

[Hopperdhh at aol.com]

Tim,
 
There was an article in January, 1960, CQ Magazine about a 3 Band Command  
Receiver that used the BC-453 as a tunable IF.  Great article.  I  built the 
receiver when I was 16 way back in 1960.  I could barely read a  schematic in 
those days.  It was by far the finest receiver a novice could  ask for.  I used 
the 3.5 Mc octal crystal from the 3-4 Mc command  transmitter so the 80 M 
novice band came in from 200 to 250 Kc -- about 10 turns  of the dial!  Total cost: 
about $25!  Over the years I've built  about 5 of them all together.  I have 
one under construction as we  speak.  I don't seem to be in a hurry to finish 
it.  There  are just too many other projects.  Talk about stability!  You can 
pick  it up off the table and slam it down and the CW note doesn't change at  
all.  What is amazing is the quality of all the components used in those  
receivers.  I also have the one that covers the BC band.  At night  there is a 
station on every 10 Kc mark.  It hasn't been aligned since it  was new.
 
Command Sets forever!

OK, I  got a couple of BC-453B's, and I see the real nice IF
transformers. BUT...  I also see some other stuff, like a nice dial and drive
and probably some  other stuff I do not yet appreciate.

It's obvious I could use the  BC-453B as a kind-of tunable IF but the
band (190-550kHz) may be less than  ideal (a different command set
receiver higher up in the HF band might have  been more appropriate there.)
Were there any HBR-themed receivers that  recycled, say, the dial drive or
the dial drive and VFO from a BC-453B or  other command receiver?

Wow, I haven't messed around with military  surplus in this way for
a couple of decades now.  Lookin' forward to a  lot of fun!

It's not like I need the VFO or dial from the BC-453B, as  I've
accumulated some other nicish drives (big dial-string Millens  and
National Velvet Verniers) over the years, but it'd be a shame
to  waste everything else in the set. Just looking to find a use
for every part  of the buffalo  :-).

Tim.
