Neat Lloyd.

The liasson trailing wire a sorta given.  I've never seen or noticed
that wire fuselage to gage-cover 'wing skin feed' in a restoration.
Suspect it's too fine to see in an old foto.

Wing-skin procedure would use fuselage as symmetry plane - a sorta
ground plane antenna rolled 90 deg.s.  So a B17 would be a kinda dipole
"comming at ya."  Feed deal wud be a sorta "gamma match."

Pal called & read ART-13 manual's B29 note (Mike H) saying  30' antenna
that's wing root-to-horiz stab-tip used > 2mcs.  Trailing wire < 2mcs

ART 13 work of genius.  Dyno has 2 wdg.s, 400 & 600.  813 gets 1kv
under 10k ft & above gets 600v.  No steenking nitrogen pressurization
Also 50khz calibrator pure art.  A regen-locked loop held in place
by 200kc xtal.  Smart dang Iowans

Maybe no separate hf command radios on B29?
