That was very much what a contact I have who used to work for Racal rather thought of thir technical expertise.
They were said to have purchased channelled radios so they did not know what frequencies they were using as they could not "manage" them!

Andy, I've no idea. Just because you are paranoid doesn't mean they
aren't listening :^) However I would think that a frequency hopping
radio is slightly easier to crack than the system used by the 4224, but
perhaps not, I'm absolutely not an expert. In the case of this 4224
someone had gone to a lot of trouble, including fitting a new eprom,
and some board re-wiring with some extra circuitry. Not the usual level
of 'skilled' work seen inside their 'surplus' equipment that I have
seen, which is of the order of fitting a nail instead of a fuse, and
replacing a capacitor by placing a big blob of solder over both wires.
