What would folks think about running the FTDX-5KMP
in Class A to drive the SPE Amp ?

I measured occupied bandwidth of an FTDX5000 after the Sept 2014 firmware update in both normal and Class A modes. The FTDX5000 is pretty clean on SSB either way, Class A is only slightly better. It's wide on CW, mostly due, I believe, to carelessness about keying waveshape and to the overly fast keying slope.

Measured data is here.
