Not much out there, but mentioned in: "Defense & Aerospace Companies - Volume II - Thorn EMI Plc - Archived 6/97"

As a private venture, Thorn EMI Electronics has
developed the Corvus, a "smart" ELINT/ESM system
which incorporates the company's EP-4220 channelized
receiver and its EP-4210 advanced pulse analyzer to
provide a high degree of mobility. Corvus consists of a
complete shelter-based, transportable installation which
can be mounted on a four-ton truck. Corvus has been
employed in the ELINT measurement roles, such as
detecting residual radiation from emitters that are
nominally switched off, but which actually are left on with
the antenna being switched off and power fed into a
dummy load.

Cheers

Having read the above it would appear that I have a 55Kg boat anchor.
