The vol high point on the 13 pin aux I/O strip is probably capable of
putting out what you need... You can find it on the power
supply/interface board. Option plug J905 I think..Pin P2-11 of that
connector...
See LBI38389b at repeater builder.

See this pdf on it's site or RB site....for the system board itself

External decoders and remotes pull audio from this point. although it
somewhat filtered, it is pretty close to buffered discriminator...if
it is not suitable you will need to tack solder to something just
after the discriminator IC.. and that area is pretty tight to work in...
The RF board is almost identical in all these 800 models...of the TMX
line... here is the PDF link of the rf board...

after looking at the schematic on page 8... I would still recommend
the vlo sq hi point as I indicated above....

Hey group
Does anyone know the points to put a discriminator tap on a TMX8810/8825?
