Andre, I am not that familiar with Motorola products, but I understand that a
number of different radios have a standard 16 pin connector for external
interface, and that the connector pin functions for most of these radios are
the same. I have no idea if the handheld radios you mention have
For some PL decoders, a weak noisy signal will trigger the PL detect and let
the signal through. On the other hand, if the co-channel signal happens to be
using the same PL tone, it will get through also. A good PL decoder like the

You left us with very little information about the problem.
I'll make the assumption that the co-channel signal is relatively distant
and weak.
Assuming that the co-channel signal is not transmitting the same tone that
you are using, your receiver should not open. If your receiver is opening,

I have an in-band repeater in VHF High that does not use cans and is a
couple of megs apart, but I had to use two antennas and separate them as far
as I could. The output of the repeater to handhelds was only 500 millawatts.
I can only say that two antennas may help some.

I recently acquired a UHF Micor mobile that had crystals for several 460
MHz splinter channels installed. Did Motorola make special 12.5 kHz IF
filters for these radios? The IF filters in this radio are stamped with
part #s 84755E01, 84755E02 84755E03. Thanks.

Bob,
Those filters are the standard 16K0F3E filters, for 25 kHz channels. The
most recent UHF Micor manual notes that part numbers 4884755E01, E02, and
E03 can all be replaced by 4884755E01. It appears that whoever crystalled

The file in question likely requires a later version of Adobe Reader than
what is being used by those having problems. Simply download the latest
version of Reader, and it will work just fine. I have Adobe Acrobat 7.0,
