can any one help how to set up and use blackcat acars decoder what equipment i need and how to set up from a radio

Do you have a link or any more info about the decoder?

I have posted Black Cat above.
Basically using scanner earphone out to computer Sound Line In.
Then run program
I have found 131.825 has most activity (Northampton UK)
Set volume gain level so green bar in software is about halfway with scanner volume at about 1 o'clock.
Squelch off
Best scanner for acars is Bearcat BC355 or one of that series. available used quite cheaply

Been monitering Acars since buying the Lowe Airmaster 2000 decades ago . Only just getting back into it as running that alongside SBS seems useful.

Alternative way is use an RTL USB Dongle with freeware - plenty of info on here and elsewhere

Have a book somewhere "Understanding ACARS" which was uploaded to the old SBS forum, Not sure if Anmer might still have a PDF copy

I have attached a copy of my frequency pi chart from ACARSHub - this should give a good idea of more active frequencies for ACARS and VDLM2. But you seemd to be on to a winner with 131.825

Black Cat has ACARS frequency list included but misses out a couple.
