[ARC5] AN/ARC-5 on MF 630 Meters

[Hubert Miller]

If anyone comes across actual instances of the BC-191 used as NDB I would really like to have that.
Ditto for use of aircraft LF transmission for group homing. The only instance I have read of for the latter
is the case of the rescue of the  Indianapolis survivors. 
OH it just occurred to me, when requesting QTE bearing from a ground station, not all ground stations
had HF DF capability. I know this is a fact from aids - to - navigation station listings I have. In this case,
the plane has to transmit on LF for the QTE. ( Was that the intention for the LF Command Set transmitters? )

Large Japanese bombers and seaplanes also had transmitters with an LF band, something like 200 - 500 kHz
but NOT covering the MF broadcast frequencies 540 - 1600 kHz. German aircraft, the larger ones, had LF
transmitters of about the same power as our Command Sets. This is the FuG10 set, sometimes written as
FuGX. There was some kind of pulse transmission the LF transmitter did, that the ground stations used to 
give bearing information back to the plane.
