That said, we will be playing with this in DSP code to see if it's
worth the trouble.
In theory it should be worth the trouble as the distortion (other than
any increased background noise) should be less than typical "hard"
clipping with a non-phase equalized filter (for the K3, that's the
KFL
Hi Bob,
It was an interesting article as are the QEX articles by the same author.
That QST article concludes that the RF amplifier likely won't be +thermally+
strained by the CESSB, as if means that amplifier stages are operating further
towards the higher efficiency point. Normal SSB has lower
The finals could handle it, just as they handle full-carrier modes like RTTY
and FM. The bigger problem, specifically described in the article, is the power
supply. Many operators who use SSB or CW only, not full-carrier modes, are
using power supplies that are barely adequate. They can handle 2
The recent article in February QST describing the CESSB mode is of
interest. Just wondering if that mode can or will be added to the code
operating the K3S? Also, wondering if the higher duty cycle of the
CESSB mode will exceed the ratings of the PA stage and that of the
KPA500? From what I
