[R-390] R-390A Dead Band

[Craig C Heaton]

Ed,

Looking at the Y2K manual; the 14mHz position on the MC knob is also common
with the 31 MC position. Y41 a 17 MHZ crystal is common to both, so if this
crystal is bad, 14 & 31 should be dead. 

If only 14 mHz is dead or lacking in sensitivity, could be a silver mica in
one of the RF cans in that octave.

Hi Folks,
     Is there one weak component that can typically be held accountable for
a dead band segment?  My 390A seems to be a fairly hot performer, except for
the 14 mHz band, which is dead.  Perhaps a crystal, or something else?
Thanks for any hints.
