[ARC5] Type 12 In WWII

Sun Aug 1 08:28:52 EDT 2021

All,
Iran was a major conduit for Lend Lease during WWII. I suggest the Cyrillic lettering was our way of letting the Russians know from whence the Jeep and equipment came. Likely this Jeep never made it over the border to Russia.
Of greater interest and perhaps more germane is the web site 
https://www.ibiblio.org/hyperwar/USA/ref/LL-Ship/index.html  which has a list of all the Lend Lease equipment we sent to our Allies. The list is very detailed by both country and item. We sent a lot of radios! Perhaps some were factory wired or modified for 12 volts like the R-148/ARC 5X that I have on my shelve.

There was also one (AFAIK only) of the AN/ARC-5 receivers made with the filaments (heaters) wired for 12-14 VDC.  This was the R-148/ARC-5X, same otherwise as the R-23/ARC-5.  In my lifetime, I have seen only one of them.  Not too long before he shuffled off this mortal coil, Marty temporarily shipped his to me, just so that I could say that I had seen one of them.  I’ve had two or three DY-1/ARR-2X.  Robert Downs  From: arc5-bounces at mailman.qth.net [mailto:arc5-bounces at mailman.qth.net] On Behalf Of Mike Morrow

Subject: Re: [ARC5] Type 12 In WWII  The 24v dynamotor for the AN/ARC-5 receivers is the DY-2A/ARR-2.  Its nomenclature was first assigned for use with the R-4*/ARR-2 "ZB" homing receiver that was used in most AN/ARC-5 receiver installations. There is a 12v version of AN/ARR-2 using the R-3/ARR-2X.  Its dynamotor is the DY-1/ARR-2X. Thus, there is a proper military dynamotor that is an exact 12v equivalent of the 24v "command set" dynamotors. There are also mechanically and electrically equivent 12v dynamotors from some USN interphone systems that would work well with no modification. For the A.R.C. Type 12 (and 11A and 17) there is the D-10(14v) equivalent to the D-10(28v) that fits earlier military receivers. Mike / KK5F -----Original Message-----

Subject: [ARC5] Type 12 In WWII  I did NOT say that Type 12 Radios were used in WWII.  I did say that I have Type 12 radios where the DM-32 dynamotor bases were used with the WWII tank radio 12VDC SCR-528/628 dynamotors so that the system could operate on 12VDC.  If they did that in the late 40's then they could have done it with SCR-274-N equipment in WWII.   By the way, I think the tank receivers used 220VDC, but that would have made no difference.
