Actually, the only problem with the illustation is that the generator
cranker
should be a *husky* young person.
Ponder for a moment what kind of batteries a pre-WW2 manpacked
field radio, with a #10 power oscillator at about 300V B+, would use.

Actually, if you paw thru a stack of Radio News magazines from the war
years, you will see a *photo* of it, this Army trans/receiver, being used
with
a handcranked generator nearby.
My impression is that it was already obsolescent by the start of war, being
relegated only to training and National Guard, as well as being a
hand-me-down
to the poor junior brother, the Philippine Scouts.
Only the receiver ( 3 x type 30 tubes ) was battery powered.
Norman Weed of CA ( i think it was he ) told me of using them in the Nat'l
Guard, and connecting a wire dipole to the loop by tapping loop at
appropriate Z match portion by means of spring clamps ( like jumper
cable alligator clamps ). This increased the range to 15 miles or more.
 But
probably didn't do much good for the stability of that 1 lonely tuned
circuit. )
The loop is square tubing, hinged at the corners, as far as i know. I do not
have the loop. I do have the BC-156, similar set but uses normal coil in
tuned circuit, and was for use with a wire antenna only.
