JMPX v2 stereo encoder with RDS. Currenly playing song title sent with FM transmitter

- Using JMPX v2 (FM stereo encoder with RDS support) to send currently playing song title via RDS so listeners can see what the currently playing song is.
JMPX is a software implementation of an FM stereo encoder, version 2 supports RDS. In this video it is shown that the currently playing song title can be sent to an RDS compatible receiver (a cell phone in this case) along with the station name. jontio.zapto.org/hda1/paradis... - Наука та технологія
wonderfull :D
thanks
Hello, love the software, especially the new version with the Digital SCA, my question / feature request is how can we update radiotext from a basic notepad text file? if this is not yet possible, could you please add it? i have a hardware encoder for the analog FM signal, but i transmit a different program on the digital SCA and need the text to reflect that, thank you from Rockin' Robert C of103.9 Experience FM in the US.
This seems to be a common request. Yes it should be something to be added. I did add 5A group that can be sent this way as someone commissioned me to do it. I'll put it on my to do list but it might be a long long time before I get around to doing it.
Hi, with a car-lighter transmitter work?
Not without hardware modification. You would have to open the transmitter up and get it to transmit mono, then bypass the low frequency and preemphasis section. It would be interesting to try. My guess is those car-lighter transmitters use a single chip that is pretty integrated so might be impossible. Still I'd be very interested if anyone has done this.
MPX contains L+R , L-R and pilot as one signal. Why did you hook left and right channels to FM mono transmitter?
That hardware transmitter used to be a stereo one but I disabled the stereo input so only one channel is being used. I assume that I plugged in both channels as I didn't know what one was the channel that modulated the signal and what one did nothing.
Awesome app!
thanks

Hello Jonti ... Please i have questions i want to ask.
I have a standard studio gadgets with Dspx encore audio processor and Eleanors transmitter .. But my station doesnt have RDS. I come across your software JMPX v2, and in your video you show us how to set it up, so should i install the JMPx software in the system i use in broadcasting in the studio ? which sound card will i now pick as all audio from the studio is routed to the audio processor and to the transmitter ... Looking forward to hearing from you ... If you are kind enough to drop your skype username i will love to chat with you and show you my gadgets and how you can help me set up the RDS
I'm not sure how you system is exactly setup. I would think what ever component is doing the stereo to MPX encoding in your system is where JMPX should be placed. A soundcard with a good SNR rating that can do 192kHz and an external card I've found better. Using a Raspberry Pi with one of the 192Khz DACs seems to be a popular option but setting things up seems to be a bit tricky for some.
What computer are you using?
windows 7 circa 2014 brand Onda. Really liked this computer.
very good software :) but one question how possible to add a dynamic PS because name of my station is big then 8 charracters thanks LOve station 12
I haven't added any facility for dynamic PS strings. I don't know if there is an official way of displaying more than 8 characters. I assume you are wanting to flip between two different PS string. You could add something like that to the code but it could have a strange effect on the receiving radio's display of the PS. A PS string is not necessarily transmitted in sequential order so to the end user looking at his or her radio it could look odd and confusing.
thanks @Jonti Olds
i mean my station name is LOVE STATION SO HOW I WILL PUT IT ?
LIKE AIROMATE DOES IT
I've not used Airomate so I'm not sure how they do it. When I have some spare time I'll have a look at how they do it and see if it's something that could be implemented into JMPX. I know RT can be more than 8 chars but I was not aware that PS could be. Anyway, I'll have a look.
So your using an external sound card?
I did yes but you don't have to
Hi, I am using Radio Dj. How can i send de Radio Text (RT) from de JMPX. Thank you, have a good year.
I'm not sure what Radio Dj is and haven't used it. Did a search and seems to be a windows program. I'm not sure.
can i use RT instead of PS to show full name ?in JMPX
Yes you can. Put your name in the RT line edit and uncheck "update RT with music title". As I recall RT can cope with about 32 char. You can put whatever you like in RT.
thanks bro i will test and reply back :)
Hola funciona con tarjeta Sound Blaster?
As long as it can do 96,000 or 192,000 bits per second I can only assume it should
Hello, could you please help me run Linux/UBUNTU. It does not find audio output .TKS
That's tricky. On Linux I build from scratch and if an error happens it's usually a missing dependency so I install the missing thing and try again. I keep doing that till it's compiled.
Hi!
Could you help me compiling a Windows build of JMPX? No experience with this kind of stuff and you are my last hope :D
That would take me quite a while to write down how to do it. Things change all the time documenting the process can be a frustrating thing as something that worked last year might fail next year. The basic process if you use MSYS2 to install everything (qtcreater qmake qt5), there might be rtaudio, jack etc to install to. When you get an error it's usually because something it needs is not installed.
good evening
My name is Eli
I would like to help
I installed JMPX
but does not generate the RDS signal
only pilot signal .
my audio card is 192kHz
but it does not generate the rds .
What OS are you using? Sometimes you may have a sound card that can do 192kHz but the OS sets the actual sample rate to 96kHz. It could be something else but I think that is likely. If you are using Window I suggest you use spectrumlab and set the sample rate to 192kHz and create a tone around 60kHz and see if the soundcard actually produces it.
Good morning Jon.
I'm Eli, I work with electronics.
I can not install JMPX on ubuntu. Could you help me?
Can you send me the procedure or another way to install it?
I tried to compile the file in ubuntu but it appears that the file does not exist.
./jmpxencoder
File does not exist
But he is not enough.
Thank you if you can help.
I can only assume it's a file permission issue in Ubuntu. I also suggest you get the latest version of the software using 'git clone github.com/jontio/JMPX' as I believe I have change the name of the executable in Linux to JMPX
Good evening.
I tried but it always appears file or directory not found when I run the ./JMPX command in the terminal
I gave permission to all files
where did you get the transmitter
For this video I made a single transister transmitter ( github.com/jontio/JMPX/wiki/One-Transistor-Transmitter-Test-example ). The stability was awful but it worked well enough for the quick test. I wouldn't recoment using this transmitter though.
@@jontiolds it connects to usb port or microphone ?
@@jontiolds sorry that i about transmitter with head jack3.5
How to make the ps more than 8 characters?
8 chars for the ps is defined in the specs I followed and can't be greater with the protocol I used.
hola amigo como puedo hacer para que cambie el titulo de la cancion automaticamente
Q: "hello friend how can I change the title of the song automatically"
On Linux it uses Dbus and mpris so most audio players will do that for you. On windows I can't remember how I did it but I think it looked at window titles for various applications such as media monkey, vlc and windows media player to figure out what was playing.
can be RDS title song from notepad
+amri muhtasyim Currently you can change the RDS text either from the options menu or from players such as VLC, Mediamonkey etc. So no, you can't use notepad to change the song title.
nice video can i send to fm in dab+ home radio's with virtual dj
No this is MPX and an analog transmission format.
Jonti hello again we have two problem the first is the software it self dont save settings after shut down second yess the RT work ok but the speed is high in scrolling if u can updat for theses suggestion and i would like an option start with window thanks HUG
Everything seems to save correctly for me after I shut down the application, have you unchecked "Update RT with music title"?. Maybe it's a problem with flipping between RT A and RT B. Try powering off the receiver then turning it back on again and see what happens.
The scrolling speed for RT on a radio is controlled by the radio itself I believe. I don't think think I have any control over that.
I'm not sure what you mean by "an option start with window". It starts with a window.
