Nothing new under the sun!
Old chestpack radar kits.
Absolutely right,Matt. In 1971 I was on the permanent staff at the School of Signals, Blandford Forum in Dorset. At the nearby Royal Radar Establishment at Malvern they had the newly developed "man pack" man portable radar on trial. Trouble was,it took THREE men to make it man portable! It was on field trials and was intended for the infantry. I always wondered what happened to this "Gee-Whiz" technology,for that is what this seeemed like at the time. We used to swap yarns,(and a lot of "Bullshit") with the guys at Malvern.
