MEXICO CITY (AP) — When convoys of soldiers or federal police move through the scrubland of northern Mexico, the Zetas drug cartel knows they are coming.

The alert goes out from a taxi driver or a street vendor, equipped with a high-end handheld radio and paid to work as a lookout known as a "halcon," or hawk.

The radio signal travels deep into the arid countryside, hours by foot from the nearest road. There, the 8-foot-tall (2-meter-tall) dark-green branches of the rockrose bush conceal a radio tower painted to match. A cable buried in the dirt draws power from a solar panel. A signal-boosting repeater relays the message along a network of powerful antennas and other repeaters that stretch hundreds of miles (kilometers) across Mexico, a shadow communications system allowing the cartel to coordinate drug deliveries, kidnapping, extortion and other crimes with the immediacy and precision of a modern military or law-enforcement agency.

...

The Mexican army said on Dec. 4 that it had seized a total of at least 167 antennas, 155 repeaters, 166 power sources, 71 pieces of computer equipment and 1,446 radios.

...

Using millions of dollars worth of legally available equipment
, Del Toro established the system in most of Mexico's 31 states and parts of northern Guatemala under the orders of the top leaders in the Gulf cartel and the Zetas. The Gulf cartel boss in each drug-smuggling territory, or plaza, was responsible for buying towers and repeaters as well as equipping his underlings with radios, according to Del Toro's plea agreement.

Del Toro employed communications specialists to maintain and run the system and research new technology, according to the agreement.


n.b.
i wonder if "communications specialist" pays like a GS15 job, plus bonus? where do i send my resume?

Taliban et all in Afghanistan have been using PTT radios/repeaters for a while now...


Same with the cartels, I've done some work I won't discuss down there with it.... interesting they listed them in the grab though.... hell of a collection

Looks like it's all VHF/UHF gear. I guess they don't know about NVIS (yet) or more likely, the NVIS stuff doesn't get
caught very often.

Repeaters, though, that's a sign of gonads and/or not understanding how DF works.

I remember reading about the Taliban using radios in Afghanistan and some internal debate on our side
about not messing with them too much, since it was generating a lot of intelligence information (locations
plus whatever we heard, I guess.)

you'd be surprised the aversion to using HF - both by them and by us

I can understand our aversion, since we have quite a few other tools in the toolbox, but HF NVIS seems
tailor-made for insurgent/guerrilla types of operations (if VHF is getting you killed, that is.) Maybe they
don't use it because VHF is largely working for them...?

Anyway, I'd think repeaters would be the main vulerability, since they're not terribly mobile. At least
with handhelds you can get away from the immediate area after a TX.

This reminded me of operations in south america I heard via FLTSATCOM back in the late '80s and
very early 90s, when both our guys and the bad guys were uplinking through the same linear transponder
(and a nerd with a UHF communications receiver and a satellite TV dish could do some interesting scanning.)

the repeaters they're using are pretty mobile - almost like an ammo can with an antenna... and also they view them as disposable

you can DF the repeater - great, they'll put another up the next week....

At night they get on 80 meters... anywhere on 80 m, and talk coded Spanish in USB.

I haven't heard them on 40 m or 20 m.

What say the hive, road trip to mexico to procure EMCOMM repeaters foir the ARFCOM net?

They may actually be using NVIS then, since 80M would be the night-time NVIS frequency to use. 40M is daytime, but doesn't
carry quite as well. I don't do much voice work, but have heard spanish on 80M, I just assumed it was mexican hams. Since I'm in
AZ I'll have to listen in the daytime to see if there's some NVIS stuff happening too.

Any way you look at it though, they're operating like a military down there, which gets a wee bit scary sharing a border with them.

Naaw alot arent, but its kind of wierd, in the middle of the states, on a 2m repeater band to hear spanish, on several different days. Worthy enough to at least have someone listen in and see whats going on.

It's an old Icom ic-W21AT running in X-band rptr mode. One of the first HT's that did X-banding. 7.5AH SLA battery. I built up that can to place on top of a mountain/hill when I went hiking. I packed an old UHF HT with me during hikes and could use it to get into the can, then into a 2m repeater if I got into trouble. I never had to use it but it was nice knowing I had it. I now have an ic-2350 mobile in the Jeep for that purpose and pack the W21AT with me now...
Note to self..I need a new HT.
I have WSPR loaded. Let me know when you want to run tests..

Cool setup on the repeater. I suspect putting that on the right hill would give you some pretty large area coverage
(of course putting it up there would be the hike!)

I'm running in RX mode on 40M right now, if you go into RX or RX/TX on 40M I'll see it on the main map and
fire up the tests. (I discovered that my vertical works great doing NVIS this morning from Casa Grande or so
on south, but the hole in coverage is in close –– so I set up a second tuner on a low half-assed dipole and I think
it'll fill in to your location.)

And my radios were all taken out by an EMP

The .gov should find out what freqs they are using, build a good radio with a looong duty cycle throw in a couple 2m quagis and jam their signal. Problem solved.

What if you took and programed in a list of know freqs into a scanner and use a micro controler to tell a radio to change freqs to the detected signal and key down for x mins. that way you drain their batteries.

Shoot with an Adruino you could make a program that scans frequencies, then based off of data from 2 or 3 other stations turns a rotor and point your antenna at their repeater. Its Harmful interference at its best. To make it even better instead of just keying down they could play Justin Bieber

without going into much

playing Justin Bieber WOULD be hilarious - and would also be effective... just jamming would work best (assuming we're talking a/the government working the problem and NOT hams) but making them listen to Bieber would be the funniest

spread spectrum jamming would work but, block out HAM freqs also - this is where we get dicey..... I'm not sure that the government is "allowed" to jam ham freqs

of course governments do it but, if the ITU would say something is a different matter.


As "we're not fighting the war down in Mexico" (we as in the US), I don't see the US doing anything pro-active to counter cross border comms.... Mexico (AFAIK) hasn't done anything either short of seizing equipment - I'm not certain on Mexico's EW capabilities so I don't know if they could if they wanted to.

It's a bit fuzzy when you switch from NVIS to conventional propagations, but figure a circle with a radius of about 200 miles.

Here is probably one of the best NVIS articles around.

It's a bit fuzzy when you switch from NVIS to conventional propagations, but figure a circle with a radius of about 200 miles.

Here is probably one of the best NVIS articles around.


Linky no work. Just an ARRL pic.

This is just me thinking how I would fix the problem, no real plans just ramblings. If you use a really good antenna with a great F/B ratio it shouldn't effect US hams to much.

If it was the .gov I would hope a Prowler could take care of a few HT's.

How about a modified HARM missile?

Try this which has a link to the PDF (It's Dean Straw's QST article)
or this which, way down on the list, has the "What's the deal about NVIS."

Here is another direct link to the PDF

Hopefully one of these works...

I don't know how much a stretch it really is to imagine our corrupt Justice Dept. (not to mention State and DHS) blaming yet another group of law abiding Americans (beyond gun owners and gun retailers) for supplying/facilitating the Mexico cartels. As opposed to the the facts WE all know about the firearms situation, something closer to 90% of the radio equipment they use probably DOES really come from the US (without aid from the US gov itself) .

I WONDER if and/or how soon DEA & other alphabets start poking sticks at HRO and the like.
