[Milsurplus] BC-342 Xtal filter question, Birthday radio...

[Philip Atchley]

Hello all,
The re-capping of the BC-342 has begun.  I did the power supply the other
day.  Yesterday I did the RF section (the three bathtubs under the shield
plate).  Since this is a working unit I'm testing it after each section is
completed to make sure everything is working at each stage.

However, there is one section of the radio that doesn't seem to be working
properly.  The Xtal phasing has absolutely no effect on the selectivity.
When turned to the "out" position it has greater sensitivity as the manual
says it should, but switching it in gives the same selectivity (as evidenced
by the 5KHz heterodynes in the SWL ranges), just lower gain.  Rotating the
control through it's range has no effect either, other than the end stop
increasing the gain.  Does this sound like a bad Xtal?  (Oh Oh!)

This set was made in 1943, so I call it my "Birthday Radio" since that's the
same year I was born!  That alone makes it worth keeping 8^)
