> I am curious as to how the World War 2 jeeps used in Korean got around
this. I would imagine a government supplied 12 volt upgrade kit.
The lower power, 10 or so WATTS transmitter output or less, did use the
original 6 Volt electrical system. These same radios also had provisions
to operate on 12 and 24 Volts.
There were 12 Volt GPW/MB electrical systems fitted to some jeeps,
and done in different ways AFTER the new owner drove it out of the
show room and straight to the FRONT.
One had an inboard 12 Volt generator between the driver and passenger
with 2- 6 Volt batteries in the cargo compartment, in back. The original 6
Volt
system remained, if you can visualize that one.
Another was the fitting of a 12 Volt generator where the 6 Volt one was,
and an additional 6 Volt battery, again between the driver and passenger.
After WW2, 1948, a MWO (Modification Work Order) 6 to 12 Volt conversion
kit was made available. It swapped out all the 6 Volt material and installed
their 12 Volt equivalents.
There were one or two items that simply had a voltage
droping resistor installed. This Kit also had Shielding for the Ignition
system: plugs, coil and distributor. It wasn't very waterproof but it did
cut down on the radio interference.
The US WW2 HF mobile sets were AM or CW (code) and just miss the AM broadcast
band. BUT, some ground fixed / aircraft type radios do receive (and some
transmit) on this band as well as the more common shortwave, amateur bands.
These sets are much larger and also required the 12 Volts.
The FM WW2 mobile sets operated up to about 40 MHz. Well below US FM
broadcast.
These for the most part can pick up VHF Lo-Band commercial or amateur bands,
if you have the right crystals in them.
I have been very brief and left out alot, but I hope this is of some
help to you.
(Really like working on this stuff.)
