Fw: [Elecraft] K1 crystals

Fri Mar 1 03:19:00 2002

David:         I remember when the discussion came out about this mod.
I was building my first K-1 at the time.
I ask at that time if this mod could be applicable to the K-1 as like
you,  I wanted to build mine right rather than changing it later.
I remember the answers I got were along the line that there was a
diffenence in the 2 rigs wherein the K-2 would realize an advantage
but the K-1 would not.  I'm sure you can take a look in the archives
and find those threads.  I would also expect that some of the folks
here will be able to quote those threads and give you the reasons why
the K-1 won't be affected by the mod.
Just to long ago and its too late at night for me to recall.
Anyway,  I can tell you that the answer I got at the time
was a resounding "  No,  it won't help  "
I'll be watching other responses to your question to see if anything
has changed in recent months.
