Hello Group,
As P25 is being rolled out worldwide, I have been hearing many stories
regarding P25 shortcomings...Such as Vocoder problems in high noise situations,
Jitter and Multipath issues from users that have converted from their
legacy Analog systems, etc . The repeater issues (If any)
Well, if it's too easy, I can give you another procedure that's a lot more
difficult, painful, and expensive. Your choice.

Fire Departments in my local area are displeased with the digital systems
I have read reports where the roaring noise of a fire in the back ground
disrupted the communications resulting in casualties.
The town I live in rolled back from a 800mhz apco p25 back to their analog VHF
system.
Stick with analog, you can't go wrong.
I see no reason for departments to convert over to p25. How much
differently will it affect communications? You know the old saying, if
analog works then why not stick with it, right?

With new systems, there are usually horror stories.

is very flat. We will be adding a 5th and possibly
a 6th tower to support areas of poor coverage. I
consider this a flaw in the original system design
for this area. There have also been

Hello all,
Big M just installed a P25 800 trunking system here that is a 5 site simulcast
system.
The M radios (xts2500 xtl5000) seem to work fairly well most of the time but
there have been some totaly garbled too.
Trying to listen on a scanner is another story, as is more garbled and sounds

Gareth,
My state transitioned to a state-wide 700/800 MHz Motorola P25 system about
2 years ago, to replace their VHF High band / VHF Low Band system. So far,
there have been a number of both complaints and accolades about the system -
and it appears that what you hear depends upon whom you

I'm looking for a couple of MSR2000 UHF receivers, in the 450~470 MHz split
(will be used at 440.750).
I might also be interested in one (1) in the 470~512 split if the price is
right, since I have a 450~470 MHz helical filter assembly from a hopelessly
dead UHF receiver and I guess I can do

Somehow, at some point, possibly about the time the compact disc was
introduced, the world started defining audio quality solely as
signal-to-noise ratio.

yes, remember the claims of 'extended dynamic range' ??
now, producers and 'artists' want every bit to be a '1'
look at a current 'hit' with Adobe Audition
it has all the 'dynamic range' of a concrete block

Hi
I'm in the process of converting a UHF R1 to R2. I've got the programming all
done and am tuning the RX.
The injection and mixer are not tuning well as the slugs are nearly all the way
out. L7-11
Has anyone done this conversion before?
Did you end up doing mods to the mixer?

Budd,
The mods I do to Sinclair Q2220E duplexers to move them to 220-225Mhz will work
well for the TPRD-1554 duplexer as well. The harness will be a bit harder to
modify, as the connectors are soldered with clamp connectors. You could make a
new harness using RG-400 or RG-223.
