Hello,

just completed my K2 to the Alinment and Test Part II.
Here i have some problems...
With the VCO test I always measure 8v at R30.
The voltmeter reading does not change at all i tune L30 or the VFO.
Thus I have thought T5 am wrongly wound. But no change after rewound it...

The Troubleshooting in the manual was not a big help.
I measured there the following voltages:

Reference Oscillator Output, Pin 1 of U4:   1.1V
VCO Output, Pin3 of U3:   0.4Vpp with an DC offset of  4v
VCO Buffer output, Pin6 of U3:   0.8Vpp with an DC offset of  4v
R30 left side:   always 8V

Can someone help me?
