I have set up a test environment with stereotool.
I use the following components:
MAirlist 6.2 software
Sound card Behringer FCA1616
I installed the plug-in. In Mairlist I set up an encoder with the plug-in and selected a channel in the sound card. It is fed directly into the transmitter (BW TX50) from the sound card. I also get a signal on the transmitter.
Under FM transmitter I have switched on under General:
I also switched on BS412.
Input gain is 0.0 db (100%)
Target level 0.00 dBr
MPX deviation 60 kHz
but no matter what I put in there, nothing changes. I always measure the transmitter with much higher values. e.g. Mod. Power 2.3 or Deviation goes out over 75kHz.
Can anyone tell me what I am doing wrong?
That sound card only goes to 96 kHz... does not perform mpx very well, not stereo separation and no RDS...
