[Elecraft] Split DX

[John W2XS]

These are the posted CW offsets (in kHz) that VP6DX is using:

CW 
160m 1827.3 +7
80m 3502.5 +25 
40m 7002.5 +25 
30m 10106.5 +7 
20m 14002.5 +25 
17m 18072.5 +7  
15m 21002.5 +25  
12m 24892.5 +7 
10m 28002.5 +25  
6m 50105 +7 501

They change once in a while depending on conditions but they usually
announce where they are listening.
Many DX stations will simply say "up".  This is where the "split" mode comes
in.  Use VFO A to listen to the DX station.  Use VFO B to find the station
that he is working and get on or near to that frequency, which can be from 1
to 3 kHz above or more. Once you master this technique, you can perfectly
zero beat the station that the DX just worked, or move a little up or down
to get away from the other callers. I find it a lot of fun, and worked VP6DX
last night with 10W on 80m under noisy conditions.

The K2 (and K3) excel in this mode of operation.  Neither the K1 nor the KX1
have this "split" capability.  RIT and XIT may work under some conditions
but it is not nearly as flexible.
