I hate to ask this question, but I'm at my wit's end with this one.
I recently installed a new customer (2.4 GHz) with a clear LOS to my
tower. The distance is less than a mile and I

bouncing around and around and around.
OFDM likes the echos, most anything else doesn't.

I moved the radio to the top of the customer's barn and am now looking
over the power lines. When I first fired it up, it wouldn't associated,

Jim,
I have run into very similar situations, where high power lines, were
the only explanation as to the interference. I was able to work around
it in some situations by adjusting the customer antenna to shoot under
the powerlines, however, this is not always possible, nor is it always

Hi,
We have a large power bar mounted on a rack that powers several servers
and switches. It keeps popping the breaker that feeds the bar. Is there
any device (ammeter?) that I can measure the amperage draw on that cord
while everything is running?
Thanks,

The problem is I don't want to power down everything to check it. I
already have a Kill-A-Watt.

When you do want to power things down, I suggest one or many of these:

Not only can you remotely reboot items via a telnet console, but these
devices show True RMS current usage. A clamp meter will show you power

Already have one... the problem is this is a 12kVa unit, so we have 8

which ports are overloaded and which ones aren't. :(

With all the damage around here due to the storms last week, I am re-evaluating my tower cabinets, etc. One thing I just realized in looking at power supplies is all of my DC power is ungrounded. That is, I use 2-prong plugs for the primary and then send DC to the radio/router/switch. Has
