the opto R10 or R11 will blow the doors off the current so called

any of the , less sophisticated , close call rigs )

I guess they use some kind of spread spectrum.

dunno about the " digital " signal intercept receiver made
by opto called the " digital explorer " ...... haven't tried it
near one of those comms suvs yet. maybe " it " could capture
some comms since it ( unlike MOST other equipment )
can " see " digital signals.

After some tests with a digital capable counter, it was able to
discover GSM carriers, and it shows the frequencies of WLANs. Also it
shows the frequency of the very short bursts which are used by MPT1327
to register or request a connection.
