I asked yesterday but part of my question didn’t appear for some reason. Having the first half of this explained in a way that made sense, I now have another question on it……
How hard is it for someone’s 2-way radio to be identified and under what circumstances would anyone bother to try? I mean, if you’re messing with police, fire, rescue, airplane towers, etc., yeah Uncle Charlie is going to waste no time enlisting the help of probably every amateur operator, military and police officer to help find the guy. But even then they’d need a court order to seize & examine the radio equipment and then prove in court it was HIM that did it. Wouldn’t they have to do major internal radio surgery to determine what radio it came from? What about my theoretical 4000 watt CB to step on people 5 States away? But unless you’re going into major illegal activity as mentioned, is the FCC going to care?
(Notice now people….I said THEORETICAL -I’m still lucky I don’t blow something up turning it on! I certainly can’t try to build one.) I’ve just heard so much about footprints on 2 way radios and such, I was just wondering how much trouble one has to go through to FIND and then PROVE what radio it is. And is the bigger the radio the easier it is to I.D.? (Like my 4000 watt CB?)
There are things against Part 95 Subpart D that I’ve seen going on for quite some time and when I wrote Uncle Charlie (which people on CB have used at least in my area for years), his response was in not so many words, as I’m reading that, unless you’re reporting a Federal crime it’s being used for or risking harm to life because of interfering with police, etc. don’t look for anything within the next 30 years.
As for the 3 or 4 thousand watt thing, again, theoretically (keyword) speaking, could it be done? Obviously not with a mag. mount mobile antenna *sizzle sizzle, melt melt* but if, say you could get your hands on industrial size capacitors, a 90 or 100 Amp. breaker for your main box downstairs some #2 solid core wire a 6′ X 6′ heat shield & a 100′ steel rod/antenna, could it be done?
John: Yeah, Part 95 Subpart D 95.426 (#26) But it says “….for inspection” NOT seizure, etc. Just watch someone bring up that argument in court someday with the way things are nowadays.
Question is, when was the last time that happened unless of course it was interfering with emergency personnel, or planes or commercial radio stations? (At least by me they don’t even care about 95.407 (b) #7 anymore.) Maybe they monitor more in certain States but they haven’t been by mine in decades. Odd why the Smokey Bears don’t have the power to enforce this stuff. That would help!

classicsat: I don’t know too much about identifying a particular transmitter by a unique fingerprint or signature, but I wouldn’t put it beyond modern laboratory grade equipment the FCC would have. But if they can grab signature in the field, they can just as easily do it in the lab, non-destructively.
More “pedestrian” is triangulating the transmitter site, which nearly anybody can do with a directional antenna.
Yes, in practice you could build a 4000W 11M transmitter and antenna, if you really knew how, and if the FCC gets complaints, they may investigate.
John: No court order is required to seize equipment. CB rules state by operating a CB radio, you agree to allow your station to be open to FCC inspection at any time. all other radio services also include this statement when you agree to get a license. FCC actions, including fines require no court action, unless the violator refuses to pay a fine, and the action is submitted to the court system for collection.
Radio footprinting software is available, and can be used to ID transmitters…. However, simple direction finding techniques can isolate a specific location. Hams do it all the time to catch violators.
Illegal CBers have been known to be caught and fined for interfering with services outside their services, since their equipment is so dirty that it transmits harmonics, which are transmissions on other frequencies olongside of the ones they are tuned to…. Someone in alaska was recently fined for interfering with air traffic control frequencies.
Best bet is to stay legal. 25 million other people could get away with it… but when you get hit with that $10000 fine… you are stuck paying it… not those 25 million other people.
