In Queensland we have to also track down the offending signal .All we use is a radio ,a beam ,and a unit that reduces the signal when you get closer and we have no problem finding signals and where they come from.
Thank You,

Hi Guys,
Thanks for the advise so far.
I have just been up to the repeater site today, and have tightened up the
squelch some so it does not open so easy.
The offending signal is still there, and I can hear it on the input of my
mobile radio.
For information, here in New Zealand we have a Gov. Radio Frequency dept,
however with the recent changes in how they now work, we (Hams) have to do
99% of the work, to track down the offender.
Once we have the information, we can forward it to them to process.
It can be easier to try and clean it up with CTCSS, change frequency, or
remove completely(not an option).
With the lack of equipment to track this down, will just have to see what
happens, and just try and stop it from getting into our RX.
The signal from the link TX, is strong enough to over-ride the interference,
and give as a clean link. Good old FM capture effect.
Regards
Kevin, ZL1KFM.
