Compared to the TS850, the IC706 is stone deaf at 136 kHz and below.
Just MHO (but not only mine).

Whilst, I don't disagree with this. The much cheaper IC-706 can be made to
work well on 136kHz. It certainly needs an LF pre-amp (build, or buy from
G0MRF) for optimum performance. However, it has 1Hz tuning steps and my Mk1
is VERY stable indeed after a few seconds warm up. This makes it useful for,
say 30s or 60s dot QRSS where long term stability of better than +/- 0.05Hz
is needed. No problems with birdies or intermod. One disadvantage is that
you can't turn off the AGC.
