The loop length is figured very close it's actual length due to the fact that
the velocity factor of the loop is very fast (close to 98%) because of the air
dielectric, unlike cable that is much slower.

Are you *sure* you mean watchdog timer, or do you mean Timeout timer??
I am sure that the watchdog timer in the modules are not causing troubles for
you. If they are, there is a reason why they are tripping and there are other
problems in the modules.
If you are talking about the timout
I have an APC SU2200 (SmartUPS, 2200VA) 3U tall, that I put new batteries in a
few months ago. So far it's just sitting, plugged in, turned off, with no load.
I got curious as to how much power it was sucking out of the wall outlet, so I
plugged the UPS into my Kill-A-Watt device and plugged
Bob,
All standard residential utility meters read out in kilowatt hours. That
is the basis for their tarrifs and billing. You are charged on the
actual kilowatt hour use. The ups reading lower on actual battery
operation MAY mean the charger is disabled and all you are seeing is

I'm looking for an IFR-COM120A or COM120B service manual or at least
some schematics. In particular, I need the Baseband tray schematic.

RGR on the velocity factor...
By actual length do you mean the length of the entire conductor, the
circumference of the loop? That could be a couple inches on VHF
cavities.
No wonder the cables I made (which I cut with the help of a network
analyzer at work to be right on 1/4 wavelength all
You can try making a cable up that is shorter than you need, then
stacking up adapters until you get the proper length. When you find the
proper combination of cable and adapters, put it on your test equipment
and see what it measures. Then make an equivalent length cable. I have
used right
I'd heard that one but forgotten it. Thanks!

I suppose some mild amount of equalization can help, but it can also
be implemented completely incorrectly and cause a lot more harm than
good.

Chuck..thanks for the reply. Actually, the antenna is for VHF and given
the size it's probaby either a unity gain or maybe 3 db at most. The
full sized Stationmasters are around 5.5 db so this one has to be less.
I looked at some Sinclair antennas and a few others but
