Jim, Dave and others,
My "opened" IC706 Mk2 performs the same as JIm's Mk2g from 500 kHz
down. Output waveforms [CW] deteriorate badly from sinusoidal when
one attempts to maximise power output. Also, the overall efficiency
is very low.
I only use my Mk2 as a driver and run it as lightly as possible. It
keys well and throws a clean stable signal through the VK2DDI Grabber
on the other side of the Tasman [on 508.1 kHz.]
Perhaps I should add that it is a poor LF receiver - lack of
sensitivity and some "birdies". It is OK at 500kHz but still
relatively insensitive.
