Mike,

If you can describe that more as a "click" rather than a "birdie", I can
offer a solution - run CAL PLL again - be certain the 4 MHz oscillator
is set first and the bottom cover is in place.  You also may want to
re-flow the soldering on RF Board U4 before doing the CAL PLL.  With the
repetitive frequencies involved, it sounds like more of a PLL problem
than a birdie.
