[Milsurplus] Research Help Requested

[Mike Morrow]

The common MAB and DAV sets were not yet available in 1942.  Instead, an earlier series of small man-borne 0.2 watt sets for various segments between 2800 and 4600 kHz could have been used...sets like the MP, MU, MV, MW, MX, MY were available in 1942.  These low power sets weighed less than 10 lbm.

The much more powerful TBX-series was available in 1942.  The receiver-transmitter is about 36 pounds, the accessory case is about 31 pounds, the hand-cranked generator is about 28 pounds, and the antenna units is about 12 pounds.  Plus the dry batteries would be needed...perhaps another 10 pounds.

The 0.5 watt portable TBY-series for 28 to 80 MHz was also available in 1942.

 The patrol that went to rescue the Goettge patrol carried a TBX transmitter-receiver.
Does anyone know what a TBX weighs? The rescue patrol was much larger than the original patrol, so I'm thinking the TBX was too heavy and bulky for the smaller Goettge patrol.

 Guys, I need some help on a research project I'm doing on the Goettge patrol, a 25-man Marine patrol that was slaughtered on Guadalcanal on August 12-13, 1942.
One curious and unexplained issue is why the patrol did not bring a radio with them. Because of that, when they needed help, they had to send a guy to swim back to the Marine perimeter, about four miles away.
Can you think of any reason why they wouldn't bring a transmitter/receiver? Size? Weight? Bulk? Lack of availability in the shoestring days of the Guadalcanal campaign? This was before the advent of the BC-611 walkie-talkies, right? In August 1942, what type of small transmitters/receivers (if any) would have been available to a 25-man Marine patrol on Guadalcanal?
As always, thank you for your help.
