Hello Jim
I note your message about narrowbanding and the comment about the MSR2000.
I have seen no info on doing so but it seems to me that the MSR200 could be
narrowbanded. The MSR is very similar to the Mitrek and it can be
narrowbanded by using a kit by a company that slips my mind.
While it is possible to use one of these narrowbanding kits, it would not be
type accepted for commercial use unless someone paid for the testing and
filed with the FCC.

This makes no sense. On the same band, with the same power, and with the
same modulation type (analog) there is no reason there should be any
loss by lowering the deviation and narrowing the receiver.
If there was a change, it is not due to making the bandwidth more
narrow. Maybe the new

That loss is likely due to the switch to digital which is required for
