Because we are interested? Seriously if you were having comm's issues and we all just pointed and laughed at you do you think that would be funny? No, these are the people that are protecting us from the dipshits of the world, I'm not going to laugh at there misfortune of issues as it hinders there ability to HELP people like you and me. Its not just like a courier's comm's that might mean a package is late, this is peoples lives we are talking about.

How is it possible to catch someone wondering the streets with his portable transmita Illegally broadcasting on police freq. I "Assume a directional antenna would provide some Idea of direction then I guess signal strength would give a very rough distance form the point receival after a few calculation ...I dont Know, but very curious..

Anybody how this w

OK I'm no expert but one way of finding the transmitter would be through the process of triangulation.

You get three people, each with a directional antenna and you work out the direction that the signal is strongest from each of the three. Where the three lines (from transmitter to receiver) intersect is the approximate location of the source.

If the source is on the move, it obviously becomes more tricky, but if the receivers are also mobile, they can "track" the source and hopefully find it.

Amateur radio users do this for fun and call it "fox hunting"

Cheers,

Re foxhunting .We used to run foxhunts every friday night on 27MHz cb but it got to a point where it was too easy and quick so we introduced both mobile foxes and ssb which meant no carrier .Trying to chase down a signal that varies with voice modulation adds a bit more of a challenge.No Yagi / beam antennas on 27 Mhz.
ACMA have fixed bases with directional antennae. When they had the manpower this would have been sorted in a very short time . Now adays it seems to take a lot to provoke them into the overtime required. They like so many government entities rely on self regulation and listening to the UHF CB we can all see that doesn't work .It is all about what we as citizens are prepared to tolerate.
Once upon a time, not so long ago, you could let your children and wife listen to CB .................

Spent MANY hours playing 'fox hunt' during my mispent youth in Kalgoorlie. EVERYONE had CBs in their cars and most Friday and Saturday nights were spent 'fox hunting' around the goldfields. Met my first true love on a hunt, behind the wheel of her Holden HZ ute. Ahh the memories
