Digital Scanning and decoding

Post by numloxx » Mon Feb 19, 2018 9:22 am

Hi all,
I ordered a few RTL-SDR usb's the other day, and decided to see what I could decode on digital.
Hardware: RTL-SDR.com sells some good products. Go for the shielded dongles.
Software: FMP24 and DSDPlus-Fastlane (There is also a free copy, but it not updated anymore. Lifetime membership is only $25USD).

A few channels I've found so far, it's a bit confusing to understand who or what they are:
493.6125 - Mostly Transperth buses. The fleet number of the bus is usually the last 4 digits of the radio id. Eg 822601 = bus 2601 etc.
505.7625 ?
491.8625 ?
491.7 ?
492.4625 ?
492.375 - Car Hire/Airport?
504.2375 ?
505.7625 ?
506.275 ?
507.15 ?
464.375 ? talk about cats??? Airfreight company perhaps?
463.6 ?
507.2625 ? volunteers?

Hope this helps get others started... very interesting hobby again.
PS. You can NOT decrypt or listen to WA Police. If you listen.. this is what you will get:

Think most of those frequencies are DMR trunk systems. So what you have to do is set up a motorola trunk system with around 4 frequancies.Use Connect + system in city.
492.100000
491.700000
492.500000
492.375000
Then search this system for talk group IDs.There is many company's,councils and business on this system with there own TGID.Different to older style of scanning where everyone had there own frequencies.
TGIDs
Willson parking 821101
Elizabeth quay sec 822201
Westbin 822401
City of Perth rubbish 820401
