[Elecraft] BFO test frequency out of range

[Craig Marscin]

Hi everyone!

I have been building SN 4078, and all has gone smoothly so far.  The 
radio is finished and works (except for the problem below) as do the SSB 
and DSP options.  I have been chasing one problem for a while however.  
When I did the BFO test the BFO Low Freq came in as 4911.23 which is 
ok.  The high freq was only 4915.77, a bit short from the 4916.3 it is 
supposed to be.  I have replaced C173 and C174 with diffrent caps (same 
value), confermed L33 is working properly and isn't shorted to 
anything.  I even removed it from its spot (kept it hooked up) and it 
didn't make a sizeable change.  The voltages at U11 pin six was 5.89 and 
pin seven was 5.3 which are within tolerance.  The DC voltages 
everywhere else seem reasonable.  The AC voltages anywhere I could 
measure seemed reasonable.  One intresting thing to note is the BFO 
chrystals seem to be the wrong frequency.  They are labled ECS V 
4.9136-S Korea G3.  This is diffrent then what the instruction manual 
states they should be labled.  The remaining chrystals on the board, 
except the VFO, are ECS V 4.9136 -S Korea J3.  A little diffrent labling 
but same frequency.  I have confirmed the rest of the chrystals on the 
board are correct.  I could be totally off track with the chrystal 
idea...  Can anyone confirm it or give me ideas as to what I might have 
done wrong?

I love this radio, but when I transmit on the upper sideband it doesn't 
suppress the carrier at all (lower sideband is fine).  I believe this 
problem is the result of the problem above since I couldn't set the USB 
filters correctly.

Thanks
