Hi.
Interesting thread. I'm a communications engineer, I have so much Storno kit here. including an almost complete SHOREACRE system.
The kit is complete with Manin-Unit, the two remote-units (ORU), two aerials and an adaptor for the main-unit and the back-packs.
I don't have the original batteries, but they seem to run well from Dry-Fit sealed lead-acid units.
The main-unit has two receivers and one transmitter. The remotes have transmitter/receiver.
the idea was to have a three-way full-duplex conversation with the ability to monitor / record at the main-unit.
If there is any interest I'll get some photos up.
Also in the ex-MOD storno collection are the lowband cqf600 base-stations from a couple of RAF bases (Used by MOD-Plod)..
