[Elecraft] Intro - just scored a K2

[Don Wilhelm]

Jerry,

If you want to upgrade that K2, download the K2ATOB instructions from 
the Elecraft website.
Then look at the first page to see the full list of upgrades - download 
the instructions for each of them.

Armed with that documentation, you can physically examine the K2 to see 
which upgrades have been installed.
Physical exam is the only way it can be done.

Elecraft still has the upgrade kits.

In addition to those upgrades, a big improvement in the IF filtering can 
be accomplished by changing to the better upgraded crystals.  Elecraft 
sells a kit of either 7 (base K2 only) or 14 crystals (for both the base 
K2 and the KSB2 adapter.

73,
Don W3FPR
