it will fit. Someday, a list member may announce that he or she just
acquired one of the subject radios, and wants to know what key is used to
operate the lock. In the event of that query, the efforts expended in the
key blank and code research will be justified. Otherwise...

about this a few years ago, the engineer I spoke with seemed not to know
that there are two standard reverse burst formats.

and GMRS radios. Even more helpful would be finding the Uniden part number
of the key in the service manual. Who knows, perhaps that part number can
be decoded by a key blank supplier in a few seconds. Perhaps I'm overly
optimistic...?

reate a CTCSS
encoder that could be switched between the two reverse-burst formats, so
they just ignored the problem.

Kevin,
Please advise the brand name of the key blank, and the key blank
identification number, of the duplicate key that that does work. This might
be something like "Curtis B173". Once we have that valuable information, it
can be added to the RBTIP "Radio Keys" data fi
peaters
in service now, both commercial and Amateur, and none of them have or need
an external preselector.

he side contacts? If not, a lot of skin oil and
other gunk can contaminate those contacts and lead to an intermittent
connection during programming or flashing. I use a Gold Guard Pen to clean
both the side contacts on the radio and the programming cable pins, if
there's any doubt about their
d.
If the program hiccups at the higher speed, a bricked radio may result.

ase. As I reported in an earlier posting on this list, that situation
is almost always going to inject an AC hum into the repeater audio. Check
to ensure that the DC power supply negative terminal is not grounded.

Jeremy,
You did not provide enough information to give you a good answer. How far
apart are the frequencies involved? How powerful is the other radio?
What I can tell you right away is that vertical separation is far, far, more
effective than horizontal separation. If both radios are going to
