[MRCA] TCM Transmitter - Marine Corps' BC-610?

[Meir Ben-Dror WF2U]

As I wrote before, I have a photo of 2 TCM’s and other equipment, like RBG receivers, an LM-* and also a BC-610 in a shelter in the Philippines, from 1945 and offered to send the photo to anyone who requests it.

Maybe for a shelter. May also have been onboard ship, and the controls simply a standard part of the production that wasn’t used or connected to anything on board ship.

I was thinking more like it being included in a shelter like the SCR-399/499. Again, I am speculating mainly on the fact that the power supply includes start and stop switches and a choke control for an AC generator. It is definitely too heavy to be humped around by hand. An if you need to run it in a forward area you will will need a generator,

I wouldn’t be so sure about fixed ground use. Fixed installations in a forward area would be still be pretty primitive. And this radio doesn’t come close to looking like it was designed to be humped ashore by assault troops to support the first or even second wave of any beach landing.

Seen em? I have two plus a power supply.  The reason I suspect they were used for advance base or beachmaster operations similar to the SCR-299/399 systems is the generator start/stop and choke push button switches on the front panel of the power supply cabinet.  They would not be included for either shipboard  or fixed ground use.

Have you seen pictures of the TCM-1 and TCM-2 radios? Those big honking sets don’t look all that portable to me.   My guess would be  on board ship or at permanent shore installations.

Was wondering if anyone knows what applications the Navy TCM transmitters were used for.  I suspect at least some of them may have been used for transportable field/ground use, perhaps with the RBM receiver, similar to the Army Signal Corps SCR-299/399 BC-610 and BC-312s or the earlier SCR 287 with the BC-191 and BC-312.  My suspicion is based on there being a remote generator start switch on the TCM's separate AC power supply, which is as big as the transmitter itself. Were the TCMs also used in shipboard applications?
