Two observations:

1) The spectra are rather disappointing. I see a bunch of stereo pilot
harmonics, much like the Rohm chips. There are also some other friends
nearby. However, they don't say what they're using for a spec an. Probably
not an HP.

2) There's not much in the way of a ground plane on their one-sided (!)
board. It's a wonder that it works at all, and this could possibly explain
the lousy spectral performance.

Did you notice:
