[ARC5] [Milsurplus] ATD Transmitter Longwave Tuning Unit Repair

[Hubert Miller]

You know what devilish thought just popped into my head?
The German FuG10 sets. They had an LF transmitter 300 - 600 kHz
as part of the set. I think it used a roughly similar ckt, MOPA with
paralleled finals. This couldn't be much more powerful than the 
ARC-5. Also - some here will know more about this - it had some 
kind of pulse modulator for DF by ground stations. I have a book
on the FuG10 system, I think an actual manual maybe, but I do not
want to divert to a major hunt for it now. I'll file this question away.
Maybe the German gear even inspired these ARC-5 transmitters. 
That may be too far a guess.
The high end of the FuG10 was 6 MHz, kind of low. I have a FuG10
LF transmitter from a destroyed aircraft at Stalingrad; it's permanently
jammed at 5950 kHz. I maybe assume that was the airfield freq. I 
should have dragged it out to photograph for the anniversary of the
end of that horrendous battle.
