[Discuss-gnuradio] Trouble resampling FM MPX signal.

[Jordan Johnson]

I have an MPX generator, Stereo Tool (http://www.stereotool.com/) that records a 192khz wav. In it, is mono, pilot, Stereo, and RDS. The only thing missing an an FM modulator. Trying the Frequency Modulator and WBFM Transmit, I have had zero luck re-producing the original signal on any FM reciever. The audio is slow, too fast, the pilot (or RDS hash, not sure which) is clearly audisble and it looks horribly malformed in the FFT.

So....

What I am expecting:

- Input 192khz-wide baseband signal containing unmodulated FM mono, stereo pilot, Stereo, and RDBS signal. 

- Have signal modulated for FM
- Work

What I get:

- None of the above.

How to reproduce.

- Use Stereo Tool and record "FM Transmitter" output to a WAV file. Use WAV file for input.

The sample rate for the FM signal is 192 and the project is 288khz. This is thwe final peice of a long-going project so any help here is appreciated.
