 Is there a legacy rationale for 150W?

Hi John.

Several years ago I persuaded Jim, N3BB to raise the issue w/ the CAC
(ARRLContest Advisory Committee).  They had already been considering the
change, and then voted unanimously to recommend 100w as the LP limit for
ARRL contests (the power applies to Sweepstakes, DX Contests, 160m plus RR
etc).

But the A in CAC is just that. .ARRL management rejected the idea, claiming
that 150w was good because it encouraged ops to upgrade their stations.  I
suspect that the manufacturers didn't like the change. But who knows.

In about 2003 I derived an equation relating power to score for the ARRL CW
Sweeps:  the difference between 150 and 100 watts is a significant 3% or
thereabouts.

No vested interest for me -- I have an FT-1000MP and for the most part
believe that ARRL does a first rate job of running the contests.

73 and best wishes for a Happy and Prosperous 2014 to all.
