Hi Rob,
Your test with a glitch counter is not a vaild
measure of interference, unless the model carrying it has been calibrated
in a "clean environment", like a radio test chamber, and the area under test has
been profiled across the user's frequency band. I've had hundreds of
glitches recorded on calibrated devices and not seen a single twitch from the
plane. FYI...

switch?
Fact: It is very unlikely anyone flying a mile away is adversely
affecting
anyone at your field, irregardless of the frequency.
Remember...the receiver
would need to see on-frequency RF that is equal or
greater from the offending
transmitter to gain control.
The above statement is unfortunately incorrect. I used to think the
same way, but I have had my mind changed. We (North Alabama Silent Fliers)
unfortunately lost our field due to construction recently. In an effort to
find a new field we tried to move to a nice spot that is around 2.5 miles from
an existing RC site. We borrowed a small glitch counter from the AMA (thanks
to Steve Kaluf) and went trhough the procedures outlined by AMA to test for
interference between the two sites. Testing was done with a .25 sized trainer
aircraft, flown pretty far out but not near as far out as I've flown an
unlimited glider. The "interfering" transmitter easily registered at the
airplane from the distant (prospective) field.
sorry to burst anybody's bubble, Rob Glover
