re: K1 frequency range

[rlpend]

If I exchange C2 with C2a to expand frequency coverage to c. 150 khz
will I need to re-peak all the filters and re-calibrate the receiver?
Thanks.

P.S.: the backlight kit is a wonderful addition to the K1.

I just made this change.  No need to re-peak the filters or re-calibrate the
frequency readout.  I did, however, have to adjust the turns on the VFO
coil, to get the VFO range in spec.  I don't remember if I had to expand or
compress the turns.  I am happy with the result.  I get about 170 khz tuning
range.  Thats an average of 17 khz per turn.  Not bad.   And the backlite is
a nice touch.
