RDS working flawlessly through cheap chinese HLLY xmitter

[alcyone]

I have a cheap 5w HLLY transmitter with RDS working flawlessly, scrolling text and all. No modification was required. I guess this can work with any transmitter.

Nice. How are you getting the RDS signal into the transmitter?
I never had any luck running it in through the main audio because of phase issues.

Kage, I am running 2 instances of Stereo Tool. 7.50 for audio processing and 5.02 to handle the RDS. 5.02 has a much simpler interface and is easier to figure out. In 5.02 I have the RDS Volume turned all the way down to 0.50%. I can't hear the pilot tone. I use a dummy input (muted mic from my webcam) and output to the same sound card outputting the processed audio. Windows volume level set to 72.

Use a bat or cmd file so they don't conflict:

set USERPROFILE=C:\Second\
"C:\Program Files (x86)\Stereo Tool 2\StereoTool.exe"

I can hear artifacts inside the "studio" aka living room when RDS is enabled. There's a sort of pulsating electronics sound. But outside the studio - dead air is just dead air. No weird sounds. No buzzing, no nothing. Except text that displays instantly.


There is no effect on the final audio output.

Apologies as my reply was somewhat rushed. The command is to run a second instance of stereo tool so that the configurations don't conflict with each other. You can create a .bat or .cmd file with the above lines. I use task scheduler to automatically launch them and run them hidden from view.
