hi hans not much to say on this one but I thought id let you know anyway.

on stereo tool it has an option to display RDS with some transmitters....well i got it to work with one of the cheap transmitters pretty well no problems tuck a while to get the volume right and all that but in the end it works fine.

if your interested in what make the transmitter was .... http://ecx.images-amazon.com/images/I/31cEtOmQwWL.jpg ..so yea some cheapish ones do work lol.

im just having fun changing the name on my radio with funny things lol. it was fun. :)

sorry I don't have a diagram for this transmitter . don't know much about it .

my radio come up with RDS on the display and I can put what I want to on the display using stereo tool.

how ever this worked I have no idea but trust me it does its just as much as a surprise to you as it is to me.

you HAVE got to get the volume right for this to work. and it is 49% on my sounds card......asus xonar.

i swear on my life it worked.

if you look on the wall you can see that green LCD like thing that's the transmitter with the front missing ( with the small black wire ) ( the transmitter come from a site called ask direct a while a go.)

freq 88.1fm

192khz on sounds card set
windows 7 64
the transmitter was stereo not mono.


( had to use an other site to host the pics but it was on my profile thankfully)

(the radio is a Roberts 202 WIFI DAB FM was not cheap )

sorry about the image quality.

I cant get much more proof than that ....I don't know all that much about the transmitter (its old) ( i do know it was discontinued not to long ago and i had to rush to get it )

all i can say is it works.. in fact next time I get on with hans on a video call ill show you then.

yes i know my wall is a mess. last nights coffee.


WHAT IS MPH.? in the modulator?

sorry i got happy with the colours>.

Thanks thats awesome!

I guess I could get one of these cards for our radio station, its cheap as chips ($120nzd)

Though it says in your first picture Asus D1 audio center?

Least I'm not the only Russell around here :)

(Asus D1 audio center) yea thats the control panel for the sound card..so you can change stuff like the EQ volume sample rate and all loads of other stuff.

basicly a control panel

MAX THIS CARD WILL DO IS.......192KHZ @ 24BIT . MINIMUM 44.1 HKZ @ 16BIT


one more thing it turns out that the groove ride touch is not the only transmitter that works with RDS....there is a another one that i have called a Belkin Tunecast 3 ( the new one with the OLED display) that all-so works.....you just have to get the volume right...

the last transmitter was a Belkin - TuneCast 2 Mobile.. i coiud not get that one to work with RDS.

I watched the photo and want to make a couple of comments.
1. Bendpass filter ON!
2.Priemfazis ON!
In general, it is almost impossible. Just what kind of miracle came in the RDS signal on modulator. Need to find a scheme where you can place the transmitter to signal MPX.
Luck!

If RDS was made after stereo (which I presume it is), it sounds and judging by the photos, very possible

As for sending an MPX signal to the unit directly, dunno if its possible (not without hardware hacks), because it would be going through the hardware stereo coder (even though it is switched to mono) but then it might be filtering out stuff that could interfere with the pilot tone, however.. Since I know jack-diddly-squat about it, it could very much pass-through an MPX signal, but don't quote me on that

However, it looks like the stereo coder is primitive enough to not filter RDS data in this unit, so thats cool ;)

Likely to remove a filter 15 kHz, which is on the audio input. Therefore, the signal passes without a problem but a question of the full stereo encoding is not!
RDS accidentally runs into the modulator and the pilot signal is not and is 100%. The pilot signal is generated stereo encoder transmitter ....
