That's been my (admittedly rather dated) experience with switchers. That =
and they don't (didn't?) have the instantaneous current reserve capacity =
of a linear and would go into 'overdrive' and/or do funny things if =
rapid/sudden demands were placed on them (e.g. CW xmitting).

Since my K2 is solar/battery powered I hadn't thought of the necessity =
of weight/size considerations when traveling. I have a little Yaesu FP-4 =
4amp linear PS I can easily carry with me anyway.

Expense, size, weight & efficiency aside I think I'll stick with linears =
in my shack ;)
