[Elecraft] K2 BFO Test fails

[kruegerbenny]

So, hello again.

First of all i want to excuse but I give you some false informations. The
8.x MHz signal I measured was/is at Pin 7, not Pin 6 of U11. I did the test
with grounding L33/X3/X4 and there's some interesting behaviour (at Pin 7):
When I ground L33/X3/X4, the measured signal is about 7.7MHz. By removing
the jumper(to ground), the frequency changes to 4.9MHz. 

After that, I changed the order of instructions:
Now I connect the probe at P7(U11) and then ground L33/X3/X4. The result:
Before grounding 8.02MHz, after grounding 4.9MHz (also when I remove the
jumper)
