[Hallicrafters] SX-111 Calib. Sig. success

[Waldo Magnuson]

    I must share my success with you.  Earlier I asked for help on why 
my calibration signal wasn't working on my SX-111.  I got suggestions 
on how to test the crystal (signal gen. and oscilloscope and look for 
resonance), and after I obtained another 100 KHz crystal (in a HC-13/U 
holder), I asked for help on how to mount it in a glass octal tube.
    I placed a bad octal tube in very hot water and after a few minutes 
I was able to twist the glass bulb from the base.  Then I used a dremil 
tool and cut the glass about 1/4 in. from the bottom of the bulb.  I 
connected the crystal holder between pins 3 and 7 and then glued the 
glass over the crystal.  Plugged in and now the calibration signal is 
loud and strong and the appearance is great.
    Thanks for all of the help, suggestions, and encouragement.
