Thanks Rich for taking care of that.  That annoying device was being a pain
in the you know what.  Thanks for taking the time to fix the issue and help
get the repeater back to normal ops.

There had been a strange carrier bringing up the 147.315 repeater for about
10 to 12 days every 90 seconds. I timed the keying of the repeater to once
every 90 seconds.  You could set your watch with it.It went beyond annoying.

The repeater technicians went to work chasing it down.  We believe it was an
unlicensed Part 15 device that was operating on the same frequency or very
near the frequency of the remote receiver link frequency.  The transmitter
was physically close enough to the repeater site to be heard on the link
receiver, but far enough away to not be a full quieting signal and very low
power.

No telling what the device was.  It could have been a home security system,
a weather station or something else that transmits a signal on a regular
basis in that part of the spectrum.  It is not unusual to find these devices
scattered around various parts of the spectrum.
Those devices have to accept whatever interference a licensed service causes
them.

A couple adjustments were made to the link receiver.  I have not heard the
constant keying of the repeater since those adjustments were made.
.

The repeater appears to be back to normal operation.
