Hi Mike, thanks for the tips, I will gather this up. I have found
that if I turn the power way down, it is not as bad. Someone had
mentioned to me that my power supply could be acting up, although it is only
drawing 22 amps on a 70 amp power supply, I suppose there could be an issue
there. As for a pattern, I have not been able to follow one as of yet,
it is very sporadic at this time. I will compile as much as I can before
he gets to the site. Thanks.

Hey Mathew I know it must be frustrating for
you but you know there is something you could be doing to help Dave
out.
1) Track the times it does this. Look for a
pattern.
2) Record the temperature at the site,
especially when it acts up. Both inside and outside temp and is the sun
shinning on the antenna when it acts up.
3) Make a list of all Xmitters in a 15 mile
range with frequency.
4) Note if this problem only shows up with one
user or all users. Or do they have to be in a certain location for it
to happen.
5) Make note what your old antenna was when you
didn't have the problem vs. the new one and did you use a new connector for
it? This checks to see if the antenna pattern has
changed.
6) This maybe out in left field but is anybody
playing with BPL in the area?
7) Nominal voltages on you supply when it
doesn't act up and what they are when it does act up.
I can't think of anything else but I'm sure
other people on the list will have some ideas to add also. Intermitant
problems like this can be the hardest thing to track down so all info you
can gather will help Dave.
73,
Mike, K1EG

Well I think with Dave's knowledge and equipment, he might be able to
see what is going on. I'm certain he will find a number of my
mistakes as I call them. I'm a tinker with a dangerous plan.
I've talked with the EE Spectrum engineer at the aviation department, he
seems to think I am riding along something as well, another frequency or
something nearby. Hopefully there is an easy answer for it.

I say throw an
isolator on the amp output. This is standard procedure for
me
anytime an intermittent spurious/noise problem shows up. It's also
standard procedure for all my comm site installations.
