I see the link to my original article was severed...

I found it in my archive files...

I thought I would start a list of radios that were used in U.S. military vehicles during WWII (as a start). It would include the type, a short description, frequency, and what it was used for. My plan is to compile a short document to be used by all wanting to know what radios were used in MVs and why. Dallas and Steve Finelli helped me with the following list.

I'm sure you folks all read the article I wrote that was published by the MVPA in Army Motors awhile back. There are an unbelievable number of different model radios that were installed in WW2 MV's. Listing everything is frustrating, and was already done and are listed in military publications you can find online. That's why I concentrated on common radios in my article that are relatively easy to find, fix, and legally use ( with a licence, of course).

You will find some questions on this forum about the GRC-9 radio. The GRC-9 is a post war radio - it was not fielded before the end of hostilities in Sept, 1945. It is slightly larger and has a wider frequency range than the BC-1306. If you're doing a BC-1306 radio that was used in the European Theater of Operations, you need to see about modifying a PE-103 power supply to actually power the radio. One of the supply problems with the BC-1306 was that the PE-237 power supplies were shipped very late to Europe. PE-103 Power Supplies that were issued with already issued BC-654 were modified to power the BC-1306 for vehicle use until a PE-237 power supply was available very near the end of the war in Europe. I would recommend anybody wishing to do this join the Military Radio Collectors Association (MRCA) and get the information you need from the radio experts on that forum to get the help you need to make the modification.

Army Radio Sales in England was selling BC-1306 radios at one time, but their stock of radios may be exhausted as of the date of this posting.

Hello Mark,
Sorry, the GRC-9 is a post War Radio. It wasn't fielded until after hostilities ended. The 1945 contract date just tells you the radio is no older than the date of the contract. The GRC-9 is a great radio, and if you're doing a between WW2 and Korea vehicle, or Korean War vehicle, that's the radio you want to use, but it's not correct for WW2.

Here is an article on same...

Dallas, wasn't the SCR-694 / BC-1306 early 1943 and GRC-9 mid/late 1945? couldn't they also use the same equipment... power supplies and such?

This may be the same issue as the late war radio jeep contracts... which were early in 1945 but some were delivered post war, October 1945.

Some say they should be considered wartime... others disagree.

A very technical fine line, and one that can be argued either way. :wink: :D :D

Here is a video on the SCR-694.

Technically, it's a Signal Corps Order Number, not a contract. Signal Corps Contracts were some sort of broad agreement to build widgets for USA.

Also, the two digit year included in all Signal Corps Order Numbers until the early 1960's is the US Federal Fiscal Year, not the calendar year. From 1932 until sometime during the second Reagan Administration, the Federal Fiscal Year began on 01 July of the previous calendar year. So anything with a "45" in the Order Number was ordered between 01 July 1944 and 30 June 1945. Of course, that doesn't tell you when it was delivered.

As a general rule of thumb for 1942 thru 1945 and 1952 through 1954, if the Order Number has 4 or fewer digits, it was placed during the previous calendar year. If it is 20,000 or higher, the current calendar year. The Order Number previously referred to is on an RT-77 transmitter and is 53906-Phila-45 assuming that I didn't mis-key it). The earliest known (to me) date on a TM 11-263 is 25 June 1946, I would assume that a preliminary was done earlier but I've never lucked out and found it.

Yes, all of the accessories made for the SCR-694 except for the vehicle mount, the canvas back pack or cover, the two wire antennas, and apparently the phantom antenna, were initially carried over to the slightly larger AN/GRC-9, This included the PE-237 until the much lighter DY-88 came out around 1949.

Minor addition - To SCR-499-(*) entry add SCR-399-(*), same as SCR-499 except in HO-17 Shelter, usually on deuce-and-a-half. And SCR-299-(*) earliest version mounted in 1-1/2 ton Chevrolet panel truck and with BC-729 antenna matching unit. All also included one BC-312-(*) Receiver, same as BC-342-(*) except 12VDC.

I am a newby with a 1945 MB and looking to convert the identity package to that which would have been used by my Grandfathers regiment. I am also perfectly daft with understanding how forums work!

I am trying to find from anyone what radio might have been mounted in a Canadian / British jeep or bren gun carrier? Is there a definitive list anywhere of what I might start hunting for - for my new toy. My grandfather served in the 8th Reconnaissance Regm't of the 2nd Canadian Division.

Thanks in Advance!
