[Elecraft] K2 no receive . . . where to start?

[Mike Geddes]

Thanks for all of the good advice!  The readers and contributers to this 
reflector are a great resource and a wealth of good information.  I think I 
discovered the problem, and it is rather simple. For some reason I had 
reversed some of the 1SV149 diodes, specifically D30, D31, D32, D33, and 
D29. Kind of a bonehead thing to do, not sure how it happened.  I have a 
theory . . . . after I stuff the board with a qty of components, I use blue 
masking tape to secure the parts prior to flipping the board over (in my pc 
board holder) and soldering. These could have fallen out, and I was careless 
sticking them back in prior to soldering.  Or . . . I could have just stuck 
the little buggers in the wrong way in the first place!  You have to pay 
attention to those thin TO-92 packages.  Anyway . . . pulled a lead off of 
one when removing it so will order a couple more and see how it works.

Thanks again for your help.

Finishing up K2 6042 today.  Have fine output on all bands, but no receive! 
I did use another HF rig to create signal for alignment . . . and I did hear 
that.  I can also hear SPOT, so think amp is okay. But nothing from antenna. 
For reference, I connected my K1 to same antenna and receive was fine.  I 
checked voltage at anode of D6 on the K2 and it is fine.  Not sure where to 
go from here. Any suggestions?

Thanks and  73,
