[Elecraft] Intro - just scored a K2

[jerry]

Thanks for the info, Don.

    I looked at the Elecraft site - the upgrade kit seems to exist - but 
I was not able to add it to a shopping cart.  The crystals are 
definitely there.  So is the SSB kit...that's really tempting.

    I should probably wait till the radio gets here.  The upgrade kit 
doesn't cost much, and neither do the crystals, but I'd feel really 
foolish if I looked in the radio, and it was already done.
