Yesterday, I stumbled upon this 1940 photograph of the US Army Signal Corps communicating via radio in the field.<\/p>\n

I bet that radio kit weighs almost as much as or more than the typical soldier!<\/p>\n

Does anyone know what model of Signal Corps radio that would be?<\/p>\n

Update…<\/strong><\/p>\n

It’s a Radio Set SCR-203 (Phillip pack saddle mounted). Consisted of:<\/em>
\nBC-228 transmitter – Transmitter, 2.1-3.1 MHz, 2 ea VT-25 & VT-50, Part of SCR-203<\/em>
\nBC-227 receiver – Receiver, 2.1-3.1 MHz, Part of SCR-203<\/em>
\nBC-235 control box – Control box, Part of SCR-203<\/em><\/p>\n

The unit was powered by various battery packs and a GN-35 hand cranked generator and used a 25 ft whip antenna (Image: W.J. Schweitzer collection)<\/em><\/p>\n

Thanks so much for identifying the equipment, Richard!<\/p>\n","protected":false},"excerpt":{"rendered":"
