Thanks Paul .I will be trying it as soon as I get onsite again .from what I can gather the problem doesn't occur very often say once or twice a day but the sites havent much traffic on them at this time so it could be occuring more often but not when we using it when it happens I will find out more in due course
Thank You,
Ian Wells,

As has been suggested, try running the repeater only from batteries
with all power supplies, charge controllers or the like off or
disconnected.
If you can be at the repeater site while the problem is occurring,
listen to local audio from the repeater receiver while toggling the
repeater transmitter off and on several times. Does the desense
occur only when your transmitter is on?
There are many possibilities either way, but in general... If it
happens only with your transmitter on I would have a serious look at
your antenna, feedline, mast, tower, duplexer for any problems. Make
sure all connections and hardware is tight. It often only takes one
loose bolt or guy wire to make trouble. Rusty/corroded hardware can
be the culprit too. Try a different antenna if that is easily done.
If the desense is still there with your transmitter off, I would
suspect interference/noise from some nearby transmitter/device.
I've been chasing a very similar problem that I believe I have
narrowed down to a bad antenna. I'll find out when I replace it in a
few days.
