I'm a bit curious about Yarra Trams radio frequencies.

I've seen and am graciously currently using @Pumper_50;'s incredible work.

Cheers mate.

I am aware that the system is a "custom analog system, based off MPT1327".

With most frequencies in the 500meg and 486/487meg bands.

When delving deeper and researching on ACMA RRL, the used frequencies are registered to VicTrack,

who also control the rail network.

**Is there a band plan, or definite system frequency limits, or any way to differentiate between Rail and Tram frequencies on the RRL?**

I've noticed that the frequency list has channels 1-4 and 8-16. But missing 5-7.

I can't seem to see any logical pattern as to the frequencies to try and determine an approximate plan though.

I've compiled a list of frequencies registered to VicTrack, in the range of 480-510mHz in the metro area.

These are as follows:
