I've completed the tests and alignment in Part II of the RF board. All
resistances and voltages are within given ranges. Everything seems to work
except that when I tune through a signal (CW or BC) in CW mode on 40 meters,
the pitch of the received signal doesn't change. The signal pops up when it
hits the first filter skirt, doesn't vary in pitch as I tune accross it, and it
disappears on hitting the other skirt. In SPOT mode, I hear the sidetone, but
nothing varies. I did the VCO/BFO signal tracing bit, and all voltages are
within tolerance.
Any ideas?
