[Elecraft] I.F. shift thoughts

[wayne burdick]

You can obtain a "quantized" version of I.F. shift with the K2, as 
someone else mentioned: just assign up to 4 different BFO frequencies 
when you set up the SSB filters (and use the same bandwidth for each). 
Hitting XFIL would then rotate through your pre-set shifts. The VFO 
will read correctly in all cases because CAL FIL offsets the VCO 
frequency to match each selected BFO setting.

However, this is not a continuous control. We could add a menu entry, 
assignable to PF1 or PF2, that would let you use the VFO knob to get 
continuous I.F. shift. This is actually on the wish list already, but 
it requires a number of fairly complex changes to the firmware. It also 
is one of many functions that we didn't implement because we were out 
of code space. There are newer chips available that do have enough 
space, so all I have to do is finish everything else I'm working on. 
Maybe next year. I think I need an understudy  :)
