Is it true or urban legend

I did one Fox Hunt in Culver City California back in 1988 and it took these guys about half a day to find me since I was on the top floor of a parking structure in a small medical building and nobody thought to look inside the parking structure.

Parked under a bridge one time. Meters would jump in either direction along the riverbed, and drop directly over our position. Upset a few people with that one.
 
There are capabilities to triangulate your position in seconds but those assets and capabilities belong to other agencies.

The FCC has more important battles to fight and 11 meters is way down in the food chain.

Snoop loops are nice, but not allowed on fox hunts. They're supposed to be a challenge.

Also, it's funny to see a dozen cars driving in circles in a parking lot trying to figure out which direction to go.

I remember when I was a teen building a modified pair of CB’s that would burst transmit your voice and cause the reciving station to switch to a random channel awaiting the next burst transmit.

The way it worked is both radios had been modified to work with a tape recorder that would record a preamble which would indicate a random channel picked by a commodore 64 then when you spoke it would be recorded on a tape loop. Once you finished, the system would play the preamble and voice at a very high speed, it sounded like a squirt. I would use the time of day to create a new seed value for the PRNG routine running in basic.

So as both users would converse all you would hear is a quick burst on a channel and nothing else for a while. You would have to move channels all the time to try and attempt to follow the convo.

On every transmit the channel on transmit and recieve radio would change to the new channel. It could go like. Channel 18 then 5 then 22 then 39 etc.. it worked great also as a countermeasure against the dipshit in the neighborhood who wanted to keydown and jam our comms. Lots of fun back then.

FCC field agents are equipped with direction finding gear, and they do know how to use it.
"Angle of arrival" (triangulation) is just one of many methods used to determine a transmitters location.

And today you could do it all in software with a Raspberry Pi.

Not taking away from what you did, because it's very cool. Just thinking of what it would look like today.

Have a dopler system. Antenna on the four corners of the roof.
It measures the difference between each one and has a circle of less showing me what direction the single is coming from. Can be on a doorstep on no time. We did a lot of fox hunts few years ago. Might have to break it out again.
Funny telling someone jaming a repeater what the color of there house and make of car in the drive.
LoL

you do realize this is an old post?
 
If you think you are safe using a 400w amp and think the FCC has better things to do; them reconsider. The first time you interfere with a fire station, or the police dept., or ambulance services, US naval vessels (been there; done that)/military communications, or - dare I say it - air traffic controllers and aircraft, they will hunt yer azz with a new found zeal.

The really neat thing? You won't know that you were interfering until you get a notice in the mail, or a knock on the door.
Roll the dice, deal the cards, and spin the wheel; you take your chances.

While in the Air Force (25+ years ago), worked with a guy (was on the same base) who pieced together/built a unit from a AN/PRC-77
that could transmit and receive on most all bands including miltac freqs. He got in all kinds of trouble, almost a dishonorable/ less than honorable discharge...and it wasn't the USAF that went after him, it was the wonderful FCC. The USAF only got involved when they found out he had used some spare parts form a Roland missile battery to build it.
 
My favorite urban legend related to channel monitoring is that I have had retired military tell me that everything said on a landline telephone is monitored by a computer at Fort Hood, TX. It has been so since the 1960s. The computer watches for key words and phrases that are related to national security. I have watched CAP downed plane drills where they triangulate the downed plan location. The Truth is Out There. Trust No One. In God we trust, All others we track.
