Folks,

   I am still fighting a problem that has been plagueing me for almost two
months now and I am at my wits end.  I am hoping someone can give me some
input as to what to try to track down.

I will just tell you what I know about it.

It happens nearly every weeknight beginning around 9:15 pm and lasting unti
9:45 to 10:00 pm, but not every night.

It will happen sometimes on Saturday or Sunday afternoons.

It virtually never happens during weekdays.

Signal degrades about 10db across all clients when this happens, the ones
with weaker signals fall offline

There is no common geography to the clients that fall offline, they are
distributed almost 360 degrees from the tower

Hardware is AP1000, 130 feet of lmr 600, two piece 1 watt amp, 8 db omni
(all hardware has been swapped since this started)
Running Karlnet

When the condition stops, all returns to normal and signals are good again

Within 300 yards of this tower are a couple of banks, a railroad control box
for crossing arms, etc., a fire station

I have been on channel 10 and channel 4 and this happens the same on both
channels

Does anyone have any idea what could be causing this, it's driving me nuts!
Has anyone else ever experienced anything like this?
