Hi:

Since there is a growing amount of Two-Way
perosns on the board, I am looking to compile a list of Perosns ( Business ) that have had problems in being Jammed Out via a
Trimble ( or Similar ) Survay Device.

So, if you have a UHF Repeater ( Anywhere )
in the US, and you have experience this buzz,
click, whitsle every 5-10 Seconds and between
the hours of 6:00am-6:00pm ( working hours )
I would like to hear from you....

Perhaps if I get a list big enough, I might
be able to do something about it.

Do they always use the input side of a pair of channels?

I'm not the user of this channel but a company I work with and monitor is a licensed user. The signal I hear besides voice traffic is a short burst of carrier which may have a click to it.

The reason I think this is on the output side is that there is no hangtime after the carrier and it only lasts <1 second. Normal voice transmissions have a 3 second hangtime. The user uses PL so I doubt they even notice it.

Just curious.

Crap guys, I tried to reply to this thread, but it ended up in another thread at the top of the list. I have had quite a bit of luck with a doppler direction finder. Usually the data is Trimble or MOSCAD data. Lots of fun. FatBoy.

What is it? Why does it cause problems? I've never heard of it before.
