Hi Leif e.a.

There is only one radio which has superb keying even on fast QSK and that is
my Ten Tec Paragon. Amazing!

OK. I do not think I have any problem here. I have a good 10A
supply. I can not run at full power, but the problems are not
changing when I change the output power. On 144 MHz the keying is
perfect at all power levels.

It seems the ALC (=driver stage gain) is not something the user is
supposed to adjust. I have also received comments saying that this
radio is known to be problematic on CW.

When set for full break-in it causes terrible keying clicks. This
mode should never be used in IC706MKIIG.
