Matt,

If tuning L1 and L2 do not procuce peaks within about 3 turns from the top
there is something wrong.  The most probable thing is that the capacitors in
the bandpass circuit are the wrong value.  Check C5 and C7 (100 pf - 101),
C4 and C8 (820 pf - 821) and C6 (4.7 pf).  My first guess is that you may
have the 82 pf (marked 820) capacitors in the C4 and C8 positions.

73,
Don W3FPR
