[Elecraft] 40 Meter Transmitter Alignment problems

[david-davis@att.net]

Kurt and All:

I should have included this in the first email.

When I test the voltages on transmit at Q7 and Q8 here are the results.

Measured voltages for Q7 are:
B = .638 VDC,  C = -44.6 mVDC,  E = 0.1 mVDC.

Expected voltages for Q7 are:
B = .6 VDC,  C = 13.4 VDC,  E = 0 VDC.

-------------------------------------------------

Measured voltages for Q8:
B = .636 VDC,  C = -46.2 mVDC,  E = 0.1 mVDC.

Expected voltages for Q8 are:
B = .6 VDC,  C = 13.4 VDC,  E = 0 VDC.


As you can see the voltages to the collector on both Q7 and Q8 are not only the 
wrong polarity but way off.  Would this represent a short to ground somewhere?  
Any suggestions?

Thanks
