If there's a public safety emblem on the car, those are the radio
engineer's cars used by counties or cities for testing purposes.

Otherwise, you've spotted a MAJOR scannist.

Imho,

Or an old fashioned HAM.

Seven on my car at last count - 1 for the stereo, 1 for the mobile phone and
5 radio type antennas (1 HF auto tune, 1 HF monobander, 2 UHF antennas, and
a combo 2m/70cm). Still need to find room for the 6m antenna......

The name was changed to protect the guilty.

you should see the " last car " in the president's motorcade.
it has so many antennae on it , it looks like a porcupine .

This one?

yea, very similar except 4 of those biggest black antennas ( 2 front
and 2 rear ) a couple more of those satellite antennas ( the short
, big around ones ) and several more misc short whip antennas ......
maybe not visible in this view. that van behind the suv looks like it
might be that mobile S.A.M ( surface to air missile ) unit that
people have been talking about that the secret service uses.
( I occasionally see the foot agents with trench coats that conceal
m72a2 LAW launcher tubes too )


interestingly enough , standing right nearby one of these mobile
commo suvs , using a Opto R-10 receiver , NONE of the
transmissions ( you can see them talking to each other and
surely some of those antennae represent packet style
node networks of some sort ) will register on the r-10.
probably spread spectrum, wi-fi or UWB based equipment
in the suv.

wouldn't you love to get a tech tour of THAT puppy ?
ha ha ha ha ha it'd probably be an eye popping
experience, no doubt the " latest and greatest " .

Unless you had their specific frequencies programmed into your R-10,
you're not gonna hear a thing.

If you were standing there with a 246 or 396 in close call mode, you
would get hits on their frequencies.

I'm speaking of the " OPTOELECTRONICS " R10 nearfield
surveillance receiver. ( the one with " intercept " on the front
panel )
the model before the R11 which was locked out on the cell bands.
the r11 had a kewler looking front panel and equipment feel .
( the more desirable r10 was NOT locked out on cell freqs )

this communications intercept surveillance receiver had NO frequency
programming keys on it ,
only the ability to " lock out " certain undesired freqs. it existed
a " decade " before the " close call " models you mention above.
it has a range ( depending on the antenna and filters on the input )
of 3 to 5 miles and more. ( depending on the power of the
transmitter too )

these extremely desirable " pro quality " nearfield surveillance
" signal intercept " receivers are still seen occasionally on ebay
but sell for many 100s of dollars nowadays.

this has nothing to do with the programmable ICOM IC-R10.


the opto R10 or R11 will blow the doors off the current so called
" close call " receivers and it " does not " find ANY of the
equipment in the mentioned comms vehicle. ( nor would
any of the , less sophisticated , close call rigs )

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.


k.................

OK, you win.

I guess they use some kind of spread spectrum.

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.
