didn't read the manual first. Duh!

track down a alarm system motion detector that was operating around 900 MHz.
Some spectrum analyzers are poorly shielded, and are practically useless
when immersed in a high-RF environment.

generation within the PA at low output levels is seldom mentioned as an
issue to watch. This is understandable, since conventional wisdom
suggests that the PA should get hotter only when driven harder.

Technical information about the above power supplies is found on the
Repeater-Builder GE Index site. Look in LBI-4806 and LBI-30867. One of the
above numbers should appear somewhere on your power supply.

When you have identified each module, please report back to the list with
your findings, and we'll go from there. By the way, will your station be
used for a commercial purpose, or will it be used for Amateur Radio or
similar service?

Hi
detector relay relaxes, PTT goes away, and the repeater
will issue its identity message and return to idle mode. I'm still
tinkering with this idea. The downside is that WWV reception varies with
the time of day and propagation factors, and a decent antenna is required.
73, Eric Lemmon WB6FLY
had a similar problem with the RC-96 controller? Note that
there is no lithium or similar memory battery inside the box that might go
bad. Oddball malfunctions like this can add more gray hairs than I want!
Any ideas, case histories, or suggestions will be appreciated.
