The rules for this specify a limit of 10 watts DC input.  Is there
any sensible way of calculating a, non-zero,  absolute lower bound for
the power consumed by the K2 driver and exciter, so as to be able to
honestly say that the PA DC input is less than 10 watts without
limiting the total current to 750 to 800 mA to make the whole
transceiver transmit mode DC input be under 10 watts. Assume a K2
with the standard output transformer windings.

Would this method work?

Put the K2 into test mode (see manual page 100) and measure the key down TX
input power (disables PA).

Your maximum allowed input power is 10W plus the figure measured.

Paul M1PAF.

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!
