[Hallicrafters] SX-117 and Strange Happenings.

Just performed a complete alignment of the SX-117 and all went well with
better performance.  Having the proper equipment to perform the alignment is
of great help of course.  Love my URM-25D signal generator.

Anyway, before the alignment, and after this alignment, I noticed I had
inverted SSB and I still have inverted USB and LSB.  I thought the alignment
would solve the problem but it didn't.  In the LSB switch position, I
actually receive USB and in USB I receive in LSB.  I swapped the (2)
crystals, 1.600khz and 1.700 kHz, and all is fine.  However, the sockets the
crystal go in are labeled the other way.  In other words, to get the USB/LSB
correct, I switched the crystal into the opposing sockets.  The 1600khz
crystal in the 1.700khz socket and so forth.  I checked the crystal
frequencies and they are exactly on frequency.

Checking the USB/LSB switching, the correct crystal is being selected.  Now
I have a dilemma where I have physically reversed the crystals into the
incorrect sockets, but the receiver works fine.  Anyone have any ideas on
what's going on here?  Is it possible Hallicrafters labeled the socket
incorrectly or put the socket in backwards.  Could someone have rewired the
switch to socket connection?
