[Elecraft] K3 - DSP IF Width Increment

[Alexandr Kobranov]

I am afraid that any changes of any steps of anything (from 50Hz to 25 
or 10Hz) have to do something with changes of DSP granularity to 10Hz 
declared by Wayne as part of some leter f/w updates.

So we have to keep all ideas for that time after this change....
