Well, I thought I would bring this saga to a close...it is a paging TX
"falsing" the 141.3 CTCSS tone just enough to kerchuck the repeater.
Try any other tone and it is quiet as a mouse! Tried moving it across
the room, still to no avail. FYI, the CAT is set up for COR & Tone.
Since this thing is being tested at a different tower than where it
will be, I am going to opt to leave it off for now and when it gets in
it's permanent home, hope the tone will work right there. All our
other machines, including the privately owned ones, have the same
141.3 tone. It's permanent home is about 15 miles away, and there are
no paging TX's there...
Thanks for all the suggestions! I sure hate I got into working on
repeaters because of the death of one of our club members, but I am
enjoying it! (Got 4 of these puppies to keep up, plus 2 APRS digis!)
