From someone I know who does SCADA for a living:
If I understand the scenario, then I would recommend wireless IO radios
manufactured by Phoenix Contact.
-They are small
-Easy to configure
-Reliable
I have them installed at several customer sites and have not had to
follow up
How about this? http://www.controlbyweb.com/webrelay/ I've used these before
and it works pretty well. If you use 2 of them together, you do not need to use
a computer.

Thanks for all these good tips. The items below are the things we have tried
so far with no success. We are using smaller channels, H-pol. Filters have
not helped the problem, noise floor is actually pretty good, C/I of about 20
on most CPE.. We are going to try the two setting changes that Daniel

Tranzeo released a new firmware update the other day that has helped my
900 system a lot. Better signal and much faster pings. I have been fighting
the same problem as you for the past couple of months.

Thanks for that, the new firmware also enables 5/10 mhz channel widths
on some of the older cards.

Well as far as I know, I just did a test upgrade though, it turned a
useless B only tranzeo into a b/g tranzeo with 5/10/20 mhz channel widths.

Curious - on those older cards does it still listen at the default of 20 mhz
channels like the older Atheros cards?

If you can dig up what chipset its using, you can figure that out.

Seems to me it is ethernet cable picking up EMP. I seem to lose a lot of
Netgear routers lately. Seems to go right through the POE and gets the
WAN port. Also Transmit side of XR2's. Always see receive side
degrading after mid path lightning strikes even a mile away.
Trango ethernet survives.
We ground our Heliax at 75 ft increments down the tower but have never
done it with shielded CAT5.
I've seen a few notes about soldering the drain to the connector and it
may work well but I recall being told by an engineer, from I think
Erico, as we discussed attachment of our copper wire
