[Hammarlund] Unstable Oscillator adjustments in the HQ-180

[Richard Knoppow]

    At one time I had a long ceramic adjustment tool with slot 
screwdriver ends. I may still have it but it disappeared after moving 
some stuff to storage.  It was very useful. For one thing it would reach 
into equipment that nothing else was quite satisfactory for such as my 
General Radio 1001 signal generator. If the tip broke I could grind it 
back to shape just as with a metal screwdriver.  It was also 
non-reactive, i.e., could be used to adjust oscillators, etc, without 
pulling the frequency.
