FM broadcast band

[VK3RX]

Some stations send RDS, but as far as I am aware, the ABC doesn't.

Those that do, some fields are populated e.g. track playing, weather, program/announcer etc. and some fields aren't.

I've used SDR# with an SDR add-on to tune FM signals to see if the fields populate or not.

Around here the only Bendigo station sending RDS is Triple M on 93.5MHz.

By looking at the signal with a spectrum scope you can see the RDS carrier if present.

1st pix is the ABC (no RDS) and the second is MMM (RDS).
