[1000mp] Question about SSB AB2 mode

[Hans Remeeus]

Hello Randy,

I never noticed excessive heat with reduced power in Class-AB2.

Yes, with CW and RTTY in Class-A there will be more heat with reduced power
as well as it is with SSB.

Always be very careful with excessive heat! It can damage your PA very
easily.
