The reason behind all this is boredom. its a scanner quiet night. Nothing is happening, as i sit here thinking what
i can do i remember some years ago tinkering around with paging decoding. I had moderate success but nothing out standing. So
i dig thru my old disks and find a copy of Pocsag Protocol Monitor (POC32) software and install it on my u beaut windows xp
machine. I half expected it not to work (xp isnt always receptive to older software).
Well surprise it worked, the best part of the software is it works thru the soundcard, so since my scanner is wired already
to the soundcard, it was a matter of enable the soundcard and typing some pager freqs in the scanner.
well it worked, but as in the past not 100% so after about 1 hour fiddling with volume controls and mixers on the computer,
enough was enough, time to add a mod to the 9000XLT (780 is still to precious to mod... maybe one day).
the mod adds what is called a discriminator output, it is sort of a output before all the filters and audio circuits,
so its a clean output and works with most data decoding software. Well how to do it? a quick search on google and bingo, to
save the time ill show you how to do it with pictures!!, yes ill do anything to help you and to get more hits on the website.
The first thing to tell you is, it is simple for anyone with basic electronic knowledge and simple tools.
you will need-
some wire not more than 45cm
a panel mount socket 3.5mm Mono or RCA(I suggest this)
a drill bit and drill
solder and soldering iron
a phillips screwdriver
it should not take long, less than 30mins.
unplug the unit and disconnect all connections
unscrew all screw 4 on each side and 2 on the back
look in the top and locate TP3 about 3 inches from the back see picture below.
