[Milsurplus] SCR-536 for TD - Infantry comm

[Hue Miller]

Here’s what the report says, in weapons section:
105mm Howitzer M-7 – no radio
3 In. Gun Motor Carriage M9 (T40) -  SCR-510 receiver
(? yes, it sez “receiver” )
105mm Gun Motor Carriage M12 (T6) – SCR-610 if practicable
( I don’t know what that means! )
These specs, along with more detailed other specs, are quoted
as being from another manual, the “O.C.M”, with an OCM item 
number for each of these vehicles. 

That’s all it actually shows, for self propelled guns.
The report’s focus was on weapons to use, to blast apart fortifications.

I didn’t know the SCR-300 couldn’t talk to other FM equipment, I 
mean quartz controlled. If that’s the case, it explains the VRC-3.
But that seems to have come pretty late. I have read about the 
“tank phone” in use, also seen a photo of some Solomon Islands
fighting where the tankphone cable is visible.

I think the damage photos in this report came from mostly German
sources, from the Maginot Line experience, and some from US
ordnance lab experiments. I noted with interest that 3 US mobile
guns could equal or outperform the German 88, altho I am sure
that gun could be deployed faster.

1943.  The first attacks on the Westwall came two years later.  The root problem with the SCR-300 was that it could not talk to anything except another SCR-300.  That problem wasn't solved for another seven years.

The TD's didn't (normally) carry SCR-510.  That was an Armor Band Set.  TD's, GMC's and Towed Artillery carried SCR-608 or SCR-610 (from late in North Africa on - prior to that they carried HF sets - which brings up the question of why they would have needed a Grunt with a Handie Talkie in 1942)

In a message dated 07/31/2011 23:25:03 PM Central Daylight Time, kargo_cult at msn.com writes: 

  "If, as will often be the case, a tank destroyer platoon is assigned to 
  furnish direct support
  to an assault platoon, the assault platoon should send an SCR-536 and 
  operator to the
  tank destroyer platoon during the operation......eliminating the necessity 
  of transmission
  of the signal through intermediate or higher units."

  This is from a planning manual for attack on the Westwall, date Sept. 1942.
  The TDs and big gun carriages used for radio, SCR-510 or SCR-610.
  So when did the SCR-300 appear?  I suppose then it would have eliminated
  any need for the SCR-536 in the vehicle and infantry platoons, for 
  intercommunication?
