Foxx Tone Machine RF

[I am the Walrus]

 I just finished up the FTM and I'm very happy with it. It is much more usable than the Tyco pedal I built a while ago. I especially like the octave effect with D3 and D4 lifted off the board. (as suggested by Mark Hammer) The only problem is I'm picking up RF on it. Any ideas how to cure this issue?

  Thanks.

Move it away of RF transmiter, perhaps..??

Is it in a metal box?

Box connected to circuit ground? (Usually through jacks.)

This is a very high-gain plan with lots of naked diode junctions. It begs to pick-up radio.
