[Elecraft] L-34 Tuning Adjustment on K-2

Thu Jan 3 23:19:02 2002

Is this second crystal mod listed on the web page?  I am also 
interested in this and could not discern which mod you are 
referencing.

Also,  I have been working on my K2 during the holidays and have 
noticed with the cold weather that the lower frequency of the BFO 
seems to be unstable when cold.  The shack is around 60F when I 
get home and turn on the radio.  With the frequency probe in TP2, 
activating the frequency counter and hitting the BAND (-) shows a 
start from a low frequency that is bouncing around until the radio 
warms up where it is stabilizing at the frequency that I recorded 
when I put the K2 together.

Anyone else seen this?  Should I be worried?

I'd suggest you do the second crystal filter modification, which
allows for a more optimal setting of L34 for CW while better
equalizing USB and LSB center pitch. ....
