Hi Kevin,
I found the IC-706 Mk1 to be a good stable receiver on 136kHz but rather
deaf. However it worked well with a with two G0MJF 136kHz pre-amplifiers
and tuning arrangement when used with a small antenna.
It was used in a 137kHz/7010kHz crossband QSO on the 14th October 2003
with the late Laurie Mayhead, G3AQC when I operated as CN2PD from Marrakech.
The Mk1 was a good CW transceiver when fitted with the appropriate CW
filter but pretty awful on SSB.

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.
