No-there won't be any difference in bandwidth, since the only difference

Hi Doug,
Does your CSI-32 have the zero-power (single chip) nVram or the
pair of xicor nVram chips? The fix is different depending on
what you have.

Yes. Using an RC-850.
White paper? Why? Program the pagers and determine the 'right code' on
the 850, and you're set. I'll probably be doing the same on a RC-210 or
810 at some point.
I would recommend staying away from the Minitor IIs. Many parts for them
are NLA - including the case/housing.
I have done this on an Scom 7k, but the Arcoms do not have this capability,
with out some major programming. The Scom has where you can included all the
tones needed in a macro, along with any voice messages (if you have the
speech synthesizer module). Worked really well, PLUS you can program the

There's some info on DPL/DCS on Mike Blenderman's web
site.
The code is basically 23 bits, 9 of which are the
3-digit octal DPL code, 3 bits are always the value
100, and the rest are parity/check bits to insure
against false decoding. It is usually sent as
frequency-shift-keying of the carrier,
With such decoders standard in most scanners now days,
I have to wonder why anyone would want such a program.

You could have swapped the two 2212 chips and the error checksum
done at power up would have loaded the default values. But every
trip is a learning experience...

Some duplexers pass the desired frequency, lose
something on each side, but then pass stuff from DC to
over 1GHz as if it's not even in the circuit. My
Celwave 526 operates that way. The bandpass tuning is
rather broad and serves to match the impedance more
than effect the bandpass of the signal.

To add to what Bob said;
Band pass/reject type duplexers are basically notch type duplexers with the
loop tuned to form a little bit of band pass effect. The cavity itself tunes
the notch and the tuned loop forms the pass band part. Most of the pass band
rejection will fall between the two
