SSB issue K3

[Mark Pride]

Just installed the KPA3 module, went from 10 watts to 100 watts - good.

On CW, full power out, no problem.

On SSB, initial voice peak drives power out to the max (100 w) but within moments, the power drops way down to say, 10 or 15 watts, then randomly spikes back up but not as a function of voice peaks.  Is there a setting I should change to get that constant SSB power out?  Seems there is something fundamentally wrong with the SSB mode on this particular radio.

I have another K3 that has been in use for several years (no problems) and made the settings the same on both but still SSB power levels vary all over the place with the new K3.

Some advice from experts here please?  Thanks in advance!


Regards,
Mark, K1RX

Did you perform a high power wattmeter calibration and TX Gain
calibration after installing the KPA3?

Have you tried the transmit power calibration procedure on your newer
K3?  I can tell you from experience that it is an essential item on a
K3 owner's list of things to do before going on the air with a new
KPA3.
