The SCR-299/399 were designed to run off 110VAC 60Hz. The PE-95 gas
generator is a 10KW 110v-only unit. I, personally, have never seen a
BC-610 running off 220v. In past discussions with my my Elmer, he
explained that they had SCR-399's on Guam and Saipan and they all ran off
either the PE-95 or "base power" which was 110v 60Hz. Although not a ham,
he was the OIC of the Signal Detachment. Whether the '610 or the
'299/'399 will actually run off 50HZ power, I do not know. The TM's would
seem to indicate not. BTW, the Signal doctrine back then was not to plan
to use, nor depend on, indigenous power sources.

Hi,

I, and a couple of other British BC-610 owners run our TXs from 50Hz mains,
in my case the domestic 230 V is stepped down to 110V using what is called a
"site transformer" - designed for outdoor power tools. The only drawback I
have noticed is the occasional loud rattling from the antenna relay when it
is powered-up, presumably its AC solenoid coil prefers 60Hz. Running the
whole TX off 220V would mean a swap of all power transformers and
mains-powered relays in the equipment, so IMHO it's much better to use a
step-down transformer of some sort to do the job and give additional shock
protection.
