What would be the reaction if Hams used 11m legally using their calls.

Well that raises a question in my "punkin' head".....

When they say "fingerprint"............

are they saying...."this radio is a 1979 Cobra 148 from Taiwan"?????

or are they saying.... "this is the same radio that was transmitting 2 days 3 hours and 42 seconds ago on this frequency"????

It is easier to believe that they could match the "dynamic appearance of the signal" across multiple transmissions.... than to believe that they can tell you the "make, model and serial number" of the radio you are using.

The correct answer is this
or are they saying.... "this is the same radio that was transmitting 2 days 3 hours and 42 seconds ago on this frequency"????

Nobody anywhere is expecting that a TX fingerprint can tell you everything down to practically the serial number. The entire idea is to identify a particular signal as being the one monitored earlier. The data can be used to positively locate a transmitter that has been in use. The most common reason for this is interference complaints. It also has military uses as well. How many times have we heard that a "person of interest" was taken out by an air strike after he was tracked because of the phone or radio he was using?

This is the correct answer. Each radio has a unique 'fingerprint' based on a bunch of technical parameters including, but not limited to, rise time, AC ripple, frequency drift, freq. offset, bandwidth, harmonic content, and others.....
Radios made by the same manufacturer around the same date would certainly have had similar characteristics when new, but as they age, and especially as they are modded and given the golden screwdriver treatment, they acquire very unique 'fingerprints'.

THIS would make me think that the FCC's aim would be to use this to prove that "transmissions being investigated" were coming from THIS radio.... to avoid the "it wasn't MY radio" defense.

Exactly. So the FCC gets enough complaints that they investigate. They show up and hear the guy throwing dead carriers, playing music etc and start RDFing. After a couple days they track him down and show up with the sheriff and a warrant. He of course denies EVERYTHING. One short transmission and the FCC have their positive the interference was coming from THAT radio. The courts handle it from there.

Without stepping on the toes of my "HAM RADIO" brothers, just let me say that I can always tell an amatuer operator on 11 meters, because they always say (in an "Inflected" voice) . . . " Oh, you're a little bit off frequency," or , "You need to turn your mike gain down." Like they're all-knowing radio-wise. Sorry to say this, but they need to stay where they belong and leave the CBers and the freebanders alone to enjoy their dxing.

I can agree with you on the frequency police, but there are a lot of operators out there who have some bad audio. Over drivin or what ever. I've been guilty of it myself while playing with different power mic, one being hotter than another.

Jim, I find both hams and non hams do this, it's kind of like the idiots that have no courtesy on the band's both 11 meters and the ham bands.
Unfortunately these people just like to play Kilohurts cop.

I find that most of those who do that are CBers that became hams. They are so used to frequencies ending in either a five or a zero that if you call on something like 14.221.7 they will call you out for being off frequency. If I choose that as MY frequency to call on, how can I be off frequency?

I imagine there must be a law. How could there not?

There is a law preventing the use of an issued callsign from one service in another.
It isn't in Part 95 or Part 97 but I did run across it once in the FCC regulations somewhere. Probably was in some administrative regs or something like that. I'd have to do some serious digging to find it again.

Clearly he is implying using it on other radio service frequencies, not stuff like that.
I ran across a seller on Ebay that used a ham call for his Ebay ID. I asked him about it and he had no idea. It was just a ID name that meant something to him that happened to be a ham radio callsign. It was not anything related to radio that he was selling. So...Stuff happens!!

I have also seen where a ham wanted to use his callsign as an email address but couldn't as someone else already was using it (probably had no clue). They thought the FCC should get involved. Good Luck with that!!

I have run into people through the years that have never heard of CB radio or ham radio and don't know the least little bit of what they are.

My thoughts: CB's stay on 11m and Ham operators stay on their bands. Then no problems.

I started on CB, upgraded to Ham and now use both, and GMRS and MURS and so on.
A large number of the members here use both as well and get along just fine following the philosophy of radio is radio regardless of the service we choose to use.
In fact this forum likes to promote all types of radio and discourage people from judging others by what service they choose to use.
