How do the coast guard pin point VHF transmissions?

I didn't think they did, if you transmit for 10 seconds even the NSA would struggle to track you.

Every coastguard station and every offshore lifeboat is equipped with a Doppler DF array. They are regularly used to help pinpoint mayday locations when a location is not given.

I don't think 10 seconds would be enough to get a fix though. Maybe if they were on the right frequency, at the right time, within range and were looking at the DF screen.

Then again, I doubt anyone is going to splash out on an airband transceiver and use it once, for 10 seconds, to annoy one pilot and endanger the life of 100's. If some idiot is stupid enough to do it once then they will probably do it again,and again and again.

They WOULD find you. The safety implications of unlicensed airband transmissions would be astronomical. The money that could potentially be lost by the affected ANSPs would motivate them to pull out all the stops to shut the offender down ASAP. Yes, we have DF at the airfields, D&D also have a nationwide triangulation capability and most aircraft also have DF. We could certainly pin it down to a specific town within a couple of transmissions and at that point the police would probably start going door to door as well as parking a couple of chopper coppers in the local vicinity.

Yes, you might get away with a single transmission but make a habit of it and you can expect a knock on the door and a custodial sentence.

Thanks i thought they could, when i was younger many years ago i went to see my uncle who worked for the coast guard in Aberdeen, they were getting some one pratting around on the radio, after 2 weeks of they guy keying up and playing music they pin pointed him to a street and then to a house and gave him a visit with the old bill. Not sure if they did anything to him for it.

ahh But they didn't have the anti-terrorism laws back then and there was no threat to national security.
After 9-11 things have changed quite substantially and not for the better in my personal opinion.
Let me put it this way, The starter of this thread has posted in a public forum that he wants a radio to talk to aircraft!
Do you not think that this has been intercepted off the internet backbone by GCHQ etc!

The coastgaurd HQ in the UK are hull and fallmouth, by the time they track you down and head to the location you could be at home with a nice cuppa.

Im not advocating you try ragchewing on the airband or marine band.

And Dover, and London and others. Not to mention that most Trinity House Lighthouses also have the equipment fitted.

A bit OT and a blatant troll post but interesting none the less.

I reckon somebody is freshening up a few new accounts before diving into a certain couple of threads over in the amateur forum...

Should be fairly obvious who they are when they start posting. ;)

EDIT: P.S. the good ol VeeEx7 should do the job.

I saw a demo quite a few years ago of something that Qinetiq were putting together for the MOD as a POC that could triangulate and provide transmitter signature as soon as the transmitter had stabilised.

Shockingly quick and accurate, assuming that has progressed (and they have access to that kit) i suspect they'd be on their way to the TX site before sender had unkeyed.
