Radio Data System (RDS)

Not privy to all the information but I know its a point of contention.

I’m not sure if this is new, or if we’ve overlooked this, but I can see 101.7 2UUS has an AF of 88.3 and 99.1, so I’ve updated that on the spreadsheet

Shame 88.3 fm has been off air for a while.

You could probably argue ever since WSFM become less Western Sydney in it’s focus that it shouldn’t be entitled to it anymore anyway…

Probably be better off re-purposing that frequency for another community license or something else more local.

Yes, in theory CADA should get 99.1 with AF.

I’d personally like Breeze/Rebel to have the freq and move to somewhere up around Colo area :slightly_smiling_face: ,

They are probably even worse at being a local station for the Blue Mountains / Nepean than WS is for Western Sydney.

Yeah “in theory”. I think WS FM lost the western sydney tag given the location of transmission is the same as the Sydney wide station. At least Cada the reception is noticeably better in western sydney (except when you are at Emu Plains).

They also pop up on my TEF as well, displaying with AF-B.
In RDS Spy & SDR Console only the filler frequency of 101.7MHz AF-B list #5 displays.
If I reset the AF in RDS SPY I can see 88.3 & 99.1 populate for a second in AF Method A table, then disappear, so the AF 's exist, but some code in group 0A I guess nulls these later frequencies in the AF List? I’d have to go revisit this again, bury myself in a book & decode the ones & zeros to determine why. Maybe another day. :grin:
Briefly; some of the AF data not completely removed from their RDS encoder.

After many years of RDS CT (Clock Time) slippage on the Triple M/SUNA TMC network it appears that the CT slippage problem has now finally been corrected.
Clock Time slippage was around two minutes slow when last looked, but now perfect. :clap: :grinning:

Nice to see how many stations have RDS now. My car radio picked up more than 40 stations with RDS in Sydney:

RDS was also received from 2BS, but on my car radio, only their RT appears and not their PS. 94.1 also gets RDS from both Wollongong and Gosford, but I was parked in a spot where the two stations where audible at the same time, so no clear RDS decode.

Long PS (LPS) has been added to Breeze & Rebel @ Canungra, Chinchilla, Gold Coast, Goondiwindi, Kooralbyn, Logan, Stanthorpe, Tenterfield & Wide Bay.

As the name implies, RDS LPS broadcasts a longer, friendlier station description than the standard 8 character limited PS.

PS: BreezeWB
LPS: Breeze 102.5 Wide Bay

Radios supporting LPS typically replace the PS display with LPS.

Well done @AJ1 & Team. :clap:

Look forward to seeing the in vehicle results of this & just how many modern new vehicles can accommodate Long PS. :slight_smile:

Fascinating pioneering RDS work in this part of the world AJ. So :sunglasses:

I can see a little of the Group 15A data in the Group Analyser of RDS Spy, but unsurprisingly nothing either in RDS SPY or SDR Console GUI to display the data output of Group 15A (Long PS).

That’s awesome thanks. Definitely makes it better to spell out Wide Bay. People know Wide Bay but don’t necessarily associate it with WB :smiley:

BTW car reception of Breeze is great across Wide Bay. Even south from Maryborough on the coast road towards Rainbow Beach as I often take that way instead of the Bruce. You only really lose Breeze when approaching Gympie.

For those with a TEF6686 portable Arduino radio, the lead developer of the firmware has added ‘Long PS’ support. Sjef used MPX off-air recordings of Breeze & Rebel GC for the LPS development/debugging.

It’s in fw v2.10 RC3 on Discord (OpenRadio Community). Enjoy.

Heres a demo:

As you can see it take a second with the normal PS for it to get the long PS

Thanks @AJ
With the new fw v2.10 & above for the TEF, I guess the user might need to be careful in distinguishing between ‘Scrolling’ Dynamic PS & LPS. (There are four different ways (methodologies) to display Dynamic PS). Tagging: @Parex11
I suspect Scrolling Dynamic PS might appear jumpy on the PS display of the TEF & still limited to the display of 8 characters at a time vs the 10 or 11 characters we can see on the video for LPS? :thinking: A flag for LPS might be nice for the next TEF firmware release? :thinking:

Can’t think of which broadcasters might still use ‘Scrolling’ Dynamic PS in Australia. ‘Sounds of the Mountains’ in Tumut, NSW did or does - highly discouraged (& annoying) of course.

Possibly some car radios are going to scroll LPS (but not static PS), which may be annoying, though not as much as Dynamic PS.

Hopefully most car radios that are new enough to support LPS have a large enough display to avoid LPS scolling.

As LPS is part of the RDS1 standard on the 57 kHz subcarrier, it will be interesting to hear reports of how many radios support it.

Yes you would think (or hope) so.

Hopefully those in Media Spy in the areas concerned can check out their vehicle radios & ask their friends & family or spread the word & you/we get some feedback in this.

I think LPS was a later enactment of the RDS1 standard, not sure what year it was introduced though. :thinking:

What would be awesome is if they added a RDS2 Flag up the top under the Advanced RDS section

Hmmm i never knew that :thinking:

Guess I better drag out my Personal Windoze laptop as my Work Computer blocks the update software and my main computer here at home I am typing this on is a M2 Mac Mini

The TEF6686 can’t see RDS2 sub carriers. It’s an RDS1 only chip.
