I had mentioned earlier that the BC221 was secured behind  the pilot seat
in a B17,  well I am sticking to that as somewhere in the stacks I have a
picture of it secured on its side behind his seat, and when I find it I
will post it. .  But, it looks like it was stored in the radio compartment
too, by just wrapping the canvas bag carry strap around a seat post.  That
seems highly unlikely to me, even though I have a pic of it stored that
way.  I would think it would flop all around and if it broke loose,  become
a flying missile in the radio compartment.

I thought there was only one BC375 jammer tuning unit, but turns out that
the TU's 6,7,8,9, and 10 units were all modified into TU's 63,64,65,66, and
60 respectively.  All contain a goniometer to sweep the spectrum of the
particularTU and jam the enemies' comm.
