[Elecraft] K2 ...Does High DC Current cause RF power to fold back ?

[Jimithy66]

Am in final testing of a K2 Ver.A kit and transmit output
will not go above 2 watts on an external power meter
and 50 ohm load when keyed or pressing Tune.

"Hi Cur" flashes briefly and power is limited to 2 watts
Display....E = 11.9  and I = 2.0  Keyed     (Un-keyed I=0.22) .

Any idea where to start looking ?

Thanks,

Jim / W1FMR
