Digital trunking systems around Sydney

Digital trunking systems around Sydney

Postby freqwaves » Sun Jan 19, 2020 3:31 pm

I have been gathering some of the digital trunking systems around Sydney from what is listed on the ACMA database. I am trying to get the systems correct with what make up the correct set of frequencies for each site.
Seem to be getting a bit confused on the difference between DMRT3 & Cap+, Con+ protocols.
Below is what my USDS100 captured:
Master Comms Horsley Park
502.5875 - con+
503.4875 - con+
502.2875 - con+
503.1875 - con+
502.8875 - con+
504.0875 - DMRT3
504.9875 - DMRT3
503.7875 - DMRT3
504.675 - DMRT3
Is what I have listed above 2x seperate systems?

Thanks, John.

You won’t see a con+ together with T3 on the same system usually
