Radio Data System (RDS)

Edge Radio Hobart on 99.3 is using Dynamic PS, but thankfully it appears to be restricted to just two lines, displaying as:
EDGE
RADIO

No RT & No PTY [0]

The PI code has been left as default of ‘0000’ which is going to be problematic for many vehicle tuners, i.e. not displaying the station’s RDS.

This is probably a RDS capable transmitter or exciter (rather than a RDS encoder) with minimalist & unskilled RDS programming, not an uncommon occurrence with some FM community radio stations.

As someone unfamiliar with the RDS standard, I’m curious: what’s the maximum line length for PS? Could Edge Radio (in whatever capitalisation) fit on one static line?

Its 8 characters including spaces.

I’ve so far only see one car (a Mitsubishi Outlander) successfully decode Edge’s RDS… And a million cars that don’t.

The Mazdas with the MZD Connect system (2013 onwards) seem to be pretty good at decoding non compliant RDS PS codes.

In case there was any confusion, I meant to say “PI code”.

107.1 Highland FM have recently made a few positive changes to their RDS data.
They’ve changed their:-

  1. PI code from 0001 to 2071 :+1:
  2. Added static RT message as: 107.1 Highland FM Heart of the Highlands :slightly_smiling_face:
  3. Changed their PTY from None to Varied

Unfortunately the

Dynamic 6 line PS remains :man_facepalming:

In other RDS news I’ve noted that C91.3 Campbelltown has changed their RT messaging sometime over the past 12 months to just two messages (that I’ve so far observed) as:
Macarthur’s Home - C91.3
[Song Title] - [Artist] - C91.3

Has there ever been a longer Dynamic PS?
I can’t recall seeing one.

Thanks @Dani-Chan. :+1: All power to the MediaSpy community.
I should have checked with you first, my poor RDS reception showed fluctuating PS earlier.

Does your RDS tuner detect RDS CT or have its clock set via RDS?
I suspect Highland FM might be transmitting Clock Time.

I can’t exactly recall a longer 6 line Dynamic PS in use in Australia.
I might need to look again at 101.1 4CBL. This station along with other’s like
Braidwood FM use/used PS to include program names, which could potentially lead to several line Dynamic PS’s. Think Katherine FM included Song Title & Artist in PS field.
SA & NT stations don’t receive too many updates to our RDS FM List.
I think 2TVR-FM is/was still using scrolling PS.
There’s potentially other unaccounted for RDS stations out there with an unknown PS type. Eg 2CBD, 5WOW, etc.
From memory there’s 4 formats for dynamic PS too, discussed here in the past.

The only time it does detect is in the DAB mode I think

Must have been the dug out eye and bloody note I sent to station management, and people say writing letters has no impact.

Yes I have the same Sony radio as you, mine will also only get the clock time from DAB, never from FM.

I can now confirm that no CT is used for 2WKT 107.1.

Not sure why they are still outputting Group 10A for PTYN, when it’s not being utilized. Several other stations like Star FM Central Coast & Radio Blue Mountains do the same thing.

I’ve also made some small changes to the Katoomba entries on our Aussie RDS List.

Can now also confirm that Muswellbrook HPON 103.3 has SkyRacn RDS.

RDS in Bailingup WA.

I think their is a bug in DBCR RT set up. It won’t display at all in my Toyota and only partial on the portable. Correct message on 98.5 and 102.1 is ‘Donnybrook 102.1FM Bailingup 98.5’.

Might require data analysis with RDS Spy to debug or at least a email report to the station’s tech.
So, just to confirm. Does the same problem also exist on 102.1MHz?

Yes, both 102.1 Donnybrook and 98.5 Bailingup appear to be configured the same and therefore behave the same.

I shall post up a screenshot of RDS Spy when I have time. For now 2 things stand out - the default F000 PI code and the use of B group codes (ie 0B and 2B). I’m wondering if any other stations use B group codes and notice display differences on different radios.

Great. Try to provide full Group Content display of Group 2B for me in RDS Spy. I reckon there could be some obscure ASCII character used or some inappropriate ASCII character used as a ‘end of text’ character that some receivers/tuners don’t no how to react to or properly. Just a thought at this stage.

I think the F000 PI code will be okay.
That code appears to be used for Vision in Portland (someone might like to confirm that) & in use by NRJ 93.5 in Noumea.

There’s some stations using Group code 0B. VOX FM do in Wollongong, but they don’t use RT. Same story with 2XX 98.3 in Canberra no RT either. UCFM in Canberra has RT with Group 2A, but also used Group 0B.

Looking at the specs, not sure why DBCR would opt for either groups 0B or 2B as Group 0B doesn’t allow for transmission of AF (it does however transmit PI code twice). With both 98.5 & 102.1 in use it would make sense to use AF capability of Group 0A.

Also Group 2A has double the RT capacity of Group 2B.

On the surface it looks like poor RDS programming by the station.
