I presume this shuts down 8T, which also takes out the driver and 
pre-driver stages, and the PA bias, although the case for eliminating 
the last one, from the DC input figure, might be marginal.

Into a dummy load on 80m I get about 800mW maximum permitted output 
using that method.  I think that contest's rules just aren't K2 friendly!
