[Elecraft] K1 RIT/XIT range

[Steve Lawrence]

I've played with adding capacitance across C7 in my K1 to increase the 
RIT/XIT range.

Here are approximate results:

as built: +3.8/-3.5
+26pf +6.4/-4.9
+35pf +6.8/-6.7
+50pf +7.7/-6.4
+56pf +8.3/-6.3
+64pf +8.5/-6.4

The above was accomplished with relatively long lead lengths clipped 
in. Values were measured on a cap meter prior to connecting.

Notes:

1) Above 50pf, the increase is marginal.
2) The "flying" leads in these tests changed the VFO range so that 
permanent installation of a replacement or additional cap will likely 
require readjustment of L1 turns spacing.

Anyone have other results?
