[Elecraft] Need a little SMD help!

Hank,

If you cannot get local help with it, I have successfully used the 
following technique to remove SMD ICs, and it should work with the diodes.

Push a length of enameled wire (largest gauge that will fit - usually 
#26 or #28) under the pin, grasp both ends of the wire, then heat the 
lead and solder pad while pulling on the wire.  Once the wire slips 
through, the lead will no longer be in contact with the pad - do 2 that 
way and the 3rd one is a snap.

73,
Don W3FPR

I guess the new robust parts are warranty, but replacing them isn't!
