Radio Data System (RDS)

Oops, must have mistyped. It was actually ore94.7. And yes, this was seen on 94.7.

A small enhancement to the PI Code Worksheet of our Aus/NZ RDS List (Google Sheets) for users.

Have added ā€˜Quick Navigation Hyperlinksā€™ to numerous PI codes (or more specifically to cells) evenly distributed throughout the length of almost 1000 PI codes/transmitter entries in the worksheet.
The purpose of this change is to avoid the time consuming scrolling action when searching for PI codes within the Worksheet for viewing or editing.
Some small GUI colour formatting changes of WkSheet 11 too (later than posted below).

A reminder in our Worksheet above, we have a column titled ā€˜PI CHECKā€™ that lists the date the PI code was last confirmed for a specific transmitter (frequency & site).
Within the sheet thereā€™s several entries that donā€™t have a date for the last time a PI code was last checked or confirmed & some entries that havenā€™t been checked or confirmed for some years. If anyone has both time & ability to confirm any missing or old PI Check dates please consider updating these entry dates based on your actual confirmed listening/dxing or RDS Encoder access. Some PI codes have a habit of changing. See below.

For any PI code changes please let us all know via this RDS thread.

For anyone without Google Sheets editing experience please note all observations here in this forum & Iā€™ll add to the list as time permits.

While watching this video (that shows a lot of what data US stations send out), I remembered that some stations here are/were meant to send traffic data for certain carsā€™s navigation systems/GPS units. Do they still do, or has it been phased out (and nobody noticed)?

Yes still alive & well across the cites & some major regional centres here.

In Australia the prominent provider is Intelematics. Still going in all Aus cap cities and some regional centres as far as Iā€™m aware. As more cars have always-on data connections, this sort of RDS traffic data will likely decline in usage.

C91.3 Macathur (Sydney, NSW) is doing some weird stuff on their RDS.

Itā€™s displaying & transmitting the dreaded ASCII NUL character in the Radio Text display in the Basic RDS Decoder of RDS Spy. This looks to be slowing down their RDS decoding, but is decoding correctly in the Radio Text Logger. (See below)

I wonder if anyone is having any RT text display issues in their vehicles? :thinking:

The other thing thatā€™s new to C91.3 is the cancer that is the usage of RDS RT for advertising.
The SE Qld RDS RT advertising usage contagion has spread to Sydney. :slightly_frowning_face:

UPDATE: The above NUL character generation appears to be originating from the VK2SWL webserver as I noted it also on 100.9 Connect FM from the same webserver, but is okay from my SDR. :thinking:

The site details listed on that web server for C91.3 are wrong, itā€™s on Mt Hercules Rd, but Iā€™m pretty sure itā€™s either known as Mt Razorback or Razorback Range, as itā€™s the same site as the TXA DTV translator site. Also itā€™s not Vertical, they have a backup Vertical antenna on the old, smaller tower, but its main antenna was changed to a mixed antenna on the taller tower many years ago.
Oh & I donā€™t think itā€™s 1kW either, I think itā€™s higher than that.

It was 1 kW vertical back when WIN3 was operational from the Nose as the elderstatesfolks on here would recall. However itā€™s not that easy to receive in tropo from down here, requiring a good level of enhancement to make an impression. Alive 90.5 outperforms it for example, so may only be running 1 kW.

ACMA has it licensed for 1kW at Razorback Range.

Yes noted that too. An ā€˜FM Listā€™ input error by someone.
Can someone here with user/editing access to FM List please login & correct this error.

Iā€™ve taken another look at the ACMA R&TV Handbook & RRF & they still list as 1kW, Vertical.
Perhaps the WIN tech or station havenā€™t advised ACMA.
I note the licence expires on Jul 31st, 2025. Perhaps the ACMA records will be updated then with the correct polarisation/power info?
:man_shrugging:
Thanks for the headsup @RFBurns :+1:

Which surprises me because the 200 watt 2MCR 100.3 community station is received almost as well as 91.3 where I amā€¦ unless they are over spec as well! (and as they are at Razorback too).

WS 88.3 is weaker than both of those.

Same here I get a much better signal for 2MCR than I do for C91.3, maybe it a slight height advantage of the 2MCR site and less blocked by the Acacia Gardens ridge??

Iā€™ll pull the correct details together for this one and submit an update request on FMList, just to confirm - the record in the ACMA spreadsheet is the correct stuff to send over?

Yes it is

2MCR is also more readily received in Bungendore than C91.3.

:thinking:

@RF Burns said the antenna was now a Mixed Polarisation array.
The ACMA records show Vertical polarisation @ 60m.
I do see a 4 bay Mixed polarisation colinear array on Google Street View at ~60m, verifying what @RFBurns said so the polarisation should be updated to Mixed.
The ā€˜simpleā€™ TX site name as @RF Burns suggested could either be Razorback Range or Mt.Razorback.
The power is probably approximately correct at 1kW per ACMA records, but I donā€™t honestly know. The reality of such things are known by the onsite engineers like RF Burns.

ACMA will fully know what the true details are, they wouldā€™ve approved the antenna change, the WIN techs wouldnā€™t have had to notify ACMA, they wouldā€™ve told them what they want, but couldnā€™t have made any changes until ACMA approved.

I canā€™t find my site photos right now so have taken this from Google Maps Street View, the original Vertical antennas are circled in Yellow (now backup), the current (main) antennas are circled in Red, with the DTV UHF antennas just above.

The C91.3 Mixed antennas were installed somewhere around the same time as the DTV translator site was built, which is about 10 years ago now, so theyā€™re not exactly new, I think the new taller tower was built for the mixed antenna array & then the DTV used that, not the other way around, but the taller tower was built prior to the DTV site, Iā€™m just not sure if it was specifically built for C91.3 or the DTV antennas.

88.9 2RSR ā€˜Radio Skid Rowā€™ now using Long PS.
I think this might have occurred today.

No RT, but it was there much earlier today.
Just RDS Groups 0A & 15A.

I wonder if any ā€˜newā€™ vehicles can decode this?
Feedback would be great.
I believe 2RSR might well be the first confirmed Australian community broadcaster to experiment with Long PS. The first Australian broadcaster being Rebel FM/The Breeze.
