-Except, despite all the speculation, no one seems to have come up with
any evidence at all of actual 2-way communications carried on by US
WW2 aircraft working on LF. I repeat my suggestion, that it was only
used for sending homing signals to other planes, such as when a scout
patrol plane made contact (sighting the enemy task force, for example) or
for another example, when the patrol plane sighted the survivors of the
USS Indianapolis and sent a homing signal for other planes, or for getting
a df-fix from a ground station. ( is this "QTE" ? can't recall )  BTW, the
trail antenna was certainly not used only for LF.
I "feel" but cannot yet quite prove, that the Germans' FuG-10  LF transmitter,
model "SL"  ( Sender, Langwellen  ), something like 150-400 kHz,which 
accompanied the FuG-10 HF transmitter "SK" ( Sender, Kurzwellen  ),
3-6 MHz, was used for the same kind of basic purpose, getting df fix from 
a ground direction finder station. I have a German DF receiver for 60 -
3500 kHz which came from an airfield, where you certainly wouldn't be using
it to DF enemy mobile communications. The transmitter also had an external
pulse modulator, which i think maybe was somehow connected with sending
a signal to be df'd, but i need information on this still.
