[Elecraft] Power control on 50MHz

[Roger Dixon]

On all other bands, increasing the power level goes in 0.1W steps up 12watts
and then in one watt steps above this.

I'm sure this used to happen on 50MHz as well.  However, now the power
increases in 0.1W steps to 8 watts and then jumps to 13W before increasing
in 1W steps.  So I can't set an output level between 8 and 13 watts, which
is just what I need for the amplifier!!!!  

Any ideas as to what I can have done to achieve this "feature" ?
