Hey all,
Was there ever a MSR 2000 built that covered the low UHF split 410ish to 440ish?
I know of the 450-470, 470-494, 494-512 splits, but is there another
low band one?
If so does anyone know the receiver part and PA part numbers for it?
Thanks,

I have found that the FIBER OPTIC modems that Verizon is installing has many

Do yourself a big favor and don't change or touch the xtal
filters in your/the MSR-2000 Receiver.
In the real world you need only reset the proper levels after

to pretty much already be able to operate narrow band.

That is Good News! I'll get with Comm Spec. and take a look! This rpt. has been

Two or three things to think about... first off the cost of a

if the controller is not easily serviced (location wise). I

Re: RC-96 Controller Problem
The "shot-gun fix" for most of the older ACC Repeater Controllers
is to replace the RAM and EEprom Chips along with some of the filter
capacitors.
Electrolytic Caps degrade over time and the power bus in this era
of controller is pretty darn noisy. At some point
Some years back, when we installed the repeater (also 146.760/160) in
a new building, we noticed a weak buzz...buzz signal ~once a second,
very near the input frequrncy. After much searching, it turned out to
be the smoke alarm heads within the building, all hard wired into
their own AC line.

OK with the ID requirement.
How else would one ID on 2.4G WiFi??

All EEPROMs have a finite life to maintain their programmed info. The earlier

Later in the 80s most were up to 10 years. Today 40 years is common. It is
