[GreenKeys] 110 DC Ships Power

[Chuck]

I served on a Victory Ship, USNS Lt James E. Robinson (ex-Czechoslovak 
Victory) in the early 60's and the "ships power" was 110 v DC.  For the 
ELINT spaces we had normal 120/60 power but the ship had the orginal power 
still hooked up and if you could find something to run from it you could use 
it.  All the wiring I saw was one line as they seem to use the ships hull 
for the return.  I have no idea if that was a good idea but seems to have 
worked.

I have a TCZ Transmitter the has two motor-generators (HV and LV + Fil) in 
it to provide power for the ART-13 sitting on the top of the cabinet.  I 
have not found a way to convert the AC to enough DC power to start/run the 
M.G. but it woulr be fun to try and see if I could get it running.

The TCZ also came with at 110/60Cy power supply for use ashore, but no one 
has seen one of them that I know of.

Thanks,
