[Elecraft] I changed K2 R98 to 1K - not good?

[Don Wilhelm]

Kieth,

The proper procedure is to temporarily use a pot in place of R98 to
determine the maximum value your K2 can tolerate without loss of power
(especially on 10 meters).  Then measure the pot and replace R98 with the
next lower standard value.

The internal gain of each K2 is a bit different, so the proper value must be
determined emperically for each K2.
