To be perfectly honest, it's a short story ... not an article.

That said, were it not for the author, I probably wouldn't be hanging out here. Out of touch for nearly ten years, I found FR while sussing out details I'd HOPED (in vain) would punch some holes in the stories he was telling me five years ago.

A few martyrs are always good for business ... plus, it's wise to off the True Believers if you can't co-opt them. Not all radicals can read the handwriting on the wall and capitalize properly on a conversion or partial epiphany of one sort or another ... (like Horowitz, Martin McGuinness or Mandela himself, for that matter).

LOL ... you're more wicked than I.

I did make it into a joke, but for a moment, I REALLY DID assume that. I thought I was bad for dwelling in the gutter at this site, until I looked down and saw all of those folks in the sewer!

Hope you won't mind my bumping you to an anonymous short story for Security-Minded sorts.
Ha!

This 'suitcase' sized deal, or the 'truck' (so-called "RF-arc zappers") are WAY TOO easy to build!!

Have any of you guys ever seen your local hams on a transmitter hunt on either 2M (146 MHz) or 70 cm (450 MHz)? A lot of them use a 5 or six element beam on top of the car to the the RDF (radio direction finding) - rotate the beam and look for strongest signal on the radio and bingo - drive in that direction!

TRANSMIT into that same antenna with a 45 Watt radio and the output of that 10 dB gain Yagi antenna becomes 450 Watts ERP (Effective Radiated Power)!

Need greater range? 200 to 300 Watt amplifiers are available for the 2M radios - into a 10 dB gain yagi and ERP s on the order of 3,000 watts can be had (of the Yagi will 300 watts of input power)!

This should be more then enough to affect most consumer/commercial electronic equipment - as well as any exposives using electrical blasting caps.

ALL this gear (excluding the Yagi antenna) are available from Radio Shack ... think about that the next time you see the local 'ham' club DFing for 'a rabbit' - it might be the local bilderberger operatives 'sweeping' *your* neighborhood for explosives instead!

Damnit _Jim ...

Must you, of all posters, show up to lend credence to the pure conjecture of a Good Night Story?

(You like this one, don't you?)

If they're Radio Shack easy to assemble, why aren't folks encouraged to protect themselves with personal Zappers -- as common as cell phones or pepper spray -- instead of letting Security Services handle it for us?

"They aren't qualified to assemble gear even as simple as this - without making perhaps fatal errors?"

Plus - they'd need a ham license (the hams are a self-policing lot who will turn in an unlicensed user of their bands in a heartbeat) ...

A) Because we are 'self-policing', b) we demand respect for the use of our bands, C) some of us operate repeaters in the ham bands and therefore act to protect our interests.

When was the last time you let some one you didn't know camp in your front yard, dig a latrine and use your hose freely?

(PS. I'm also a ham.)

Clearly, I don't understand the concept at work here. Back in the '70's when CB's were the rage, we talked to HAMs cross-country all the time. Now, if they were talking "on our level", I can understand.

Is the channel or frequency space just so limited that folks guard their reach zealously so as not to get walked on or what?

Assuming average Joes were licensed to "pulse" at will ... that would be the equivalent of popcorn popping continually on your receiver?

I guess I was operating under the impression that run-of-the-mill RF arcing would take place as someone approaches their house, car, office or small plane and a single pop would do it.

For a while in high school I thought I might be interested in ham radio, but I was quickly put off by the daunting licensing requirements. Acquiring proficiency in morse code was just the beginning, and that entitled you only to communicate in code, and on restricted frequencies. To be licensed for voice required superior morse code proficiency, plus a considerable understanding of RF electronics.

Though I think licensing requirements may have eased up someone since then, I can certainly understand why a license is evidence of a lot of study and achievement. It makes sense to me that licensed hams would resent the intrusions (into their limited bandwidth) of uncredentialed poseurs and wannabes.

Back in the '70's when CB's were the rage, we talked to HAMs cross-country all the time. Now, if they were talking "on our level", I can understand.

You were talking to *other* CBers. I started in 'radio' about that same time and do not -ever- remember hearing, or talking to, 'hams'. At that point in time, the rules on CB operation (if you will recall) were rather strict as to who you could talk to on certain channels - and, to boot, Hams and CBers *never* shared any common frequencies.

Licenses were also *required*. (It wasn't the free-for-all that it is now.)

Is the channel or frequency space just so limited that folks guard their reach zealously so as not to get walked on or what?

Hams are courteous. If you recall again, it was 'mayhem' on those first 23 channels (before more spectrum was allocated for 17 more making 40 total) - especially when the 'band' was open. You couldn't talk two or three miles local sometimes with the 'skip' was rolling in.

Hams enjoy TONS more spectrum (frequencies - if you will) than CB ever has had, and are probably 3rd or so in the lineup as far as dedicated spectrum overall. The biggest users are broadcast (AM, FM TV, satellite), 2-way users incl local govt, and the US Govt.

Hams enjoy enough spectrum that we aren't "on top of" each other - we have some spectrum that works well for country-wide coverage at night, some that works well during daylight hours, and still other spectrum that works well day or night.

We also enjoy spectrum in the VHF and UHF area adjacent to the 2-way public safety and busines radio services work. These frequencies are used with a lot of the same 2-way radios that the public safety people use (like Motorola and GE). We also had 'telephonce interconnect' (phone patches) with this equipment decades before any cell phones appeared on the scene!

Hams also have *legal* power limits that far and away exceed 'CB', which legally used to be "5 watts DC into the final PA stage" which equates now tro about 4 watts RF output. SSB CB is around 12 to 15 watts PEP. Ham, by contrast are allowed something over like over 1,000 (one thousand) watts (somewhat dependant on band in some areas) output power. (I think max ham output power might be actually around 1,550 watts, but since I don't quite approach that limit I'm not concerned ...)

So, between a lot of availble spectrum, general courtesy, coordination in the use of the VHF and UHF spectrum (via VHF Repeater Coordination Commitees and the like) we cooperatively use our spectrum to the benefit of all hams.

Assuming average Joes were licensed to "pulse" at will ... that would be the equivalent of popcorn popping continually on your receiver?

... yes ... and it wouldn't that hard to find, either. I've tracked down and located malfunctioning gear of all types, 1) from active TV antennas (set top mounted types like the Radio Shack ATV-1000) and several brands as used on RV/motorhomes, 2) malfunctioning telemetry on a city water tank 3 mile away, 3) malfunctioning paging services in the UHF band and others ...

I guess I was operating under the impression that run-of-the-mill RF arcing would take place as someone approaches their house, car, office or small plane and a single pop would do it.

One thing - detonating an electrical detonator doesn't require an arc - just electrical current (DC or AC or even high frequency AC like RF will do it). A 5-watt 2-way radio as carried by the poh-leece or a firefighter could do it. 600 milliWatts from a cell phone probably wouldn't (unless you were right on top of the device).

There cautions printed on those things listing the cautions - and safe distances - to be observed.

errata (before I'm called to task by a fellow ham):

1,500 watts = 1,550 watts

My days in EOD supporting Tech Services Division in USSS were ended 7 years ago when I retired. Professionalism requires me to keep my mouth shut, so please just assume that a "I don't have a clue" answer for ya on this matter.

All I'll suggest is that everyone here get out their little booklet and paperwork that came with their own personal cellular phone. Inside that packet somewhere is a statement/warning to not operate the phone anywhere near a electric blasting cap or blasting operations ..............

You read between the lines. Stay Safe Bert.....

The guts had been removed and very carefully replaced with a very sophisticated solid state nitrate sniffer. The device was now impossible to detect in its new casing and was far more sensitive than the most well-trained bomb-sniffing dog.
I may have or may not have once had a client that designed and made things like this. Very cool stuff, but also very invasive. You can really test for almost anything you want to.
