Re: RDS & New Vehicles

I ran across some radios that don’t display the 64 character RT field unless it is encoded with RT Plus. If no RT Plus, the RT doesn’t display at all. RT Plus is an add on feature of RT that splits the title and artist into two separate fields.
Just more to add to the many, many standards of radios out there.
I put a Kenwood radio in my truck with a display button. Pressing the button toggles the radio display between Frequency – PS – RT – RT+. This is the most flexible RDS radio I found, nicely displays all the possible fields.

RDS isa standard that every receiver manufacturer interprets differently. The good thing about standards is that there are so many of them...
I have installed several RDS encoders and found that almost no two radios display it the same way.
If you are trying to use dynamic PS, there is even more madness. My old 2007 Ram would dutifully display dynamic PS as well as scrolling or long RT messages via it's INFO button. My new Ram scrolls the PS once and hangs forever on the last 8 characters of the too long PS. My new Ram will show about the first 32 (IIRC) characters of a long or scrolling RT and offers no way to see the rest of it.
One of my clients using a PiraCZ encoder has a vehicle that displays the dynamic PS & RT perfectly and another vehicle displays only the RT... Another shows the scrolling PS but nothing of the RT whether scrolling, long or short.
I would suggest putting test txt in the various fields to ID them on various radios and then play with your txt lengths and locations to find a good compromise (if one exists...).
Be aware that a lot of radios store the PS field until the PI changes...
I am sure that there are a million RDS war stories on the list...
