Guess time will tell (again). Please try once more, and I sincerely apologize for your wasted effort previously. My new web site have such horrendously gigantic upload/download quotas that I don't think I'll EVER exceed them, so have at it! 73, Tom N0SS _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Well we are moving right along. Just got to the Second aliignment and test
section na dthe 4 mhz osc calibration went fine. The PLL reference range test looked good and the range was right in the middle of the road. But when I plugged the freq probe in TP1 and did a cal factor to check the VCO is says 000000. I am going though all my assembly now to make sure I did not miss anything. Can anyone think of any common mistakes I might be overlooking? Thanks and 73, Rich _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

Hi
The most common problem is with the is T5. Make sure it is wound right and the leads are stripped properly.

Rich,
Be certain the frequency counter probe is still working by plugging it into TP3 again, then -- Check T5 to be certain you have well tinned leads and good solder joints. Then check the orientation of D13. Check soldering on all components shown in the schematic VFO section (RF board sheet 1 of 4), and while you are at it, check the components for proper values. If all the above is correct, the VFO should oscillate (and produce an indication on the frequency counter). Try the probe on pin 3 of U3 to see if you get anything there, if so, you should have a good frequency reading at TP1 unless U3 is not working correctly. 73, Don W3FPR ----- Original Message ----- > Well we are moving right along.

This group is awesome :)
Yea I was being stupid !! Was so particular about winding the torroids and then when I installed T5 reversed it. So now I have a signal.. Thanks Don, Don and Tom !
