Same here. I have to overload a little ALC and CMP and it solves almost all the problem, but it continues. Before the k3 i owned an Icom 7700 and with the correct ALC and CMP it had a very stable SSB Power.
I am sure it can be solved with a firmware update. El 28/03/2010 20:30, Jan Erik Holm escribió: > Doesn´t seem to be a fix.
