ESSB Problem 40m

[N4LQ-2]

When using ESSB, any bandwidth, on 40 meters, LSB output power drops about
50% compared to USB. Turning off ESSB gives 100% power in either mode.
I reloaded the latest firmware, 2.23, no change.
20 meters is 100% output on either sideband.
Suggestions?

I just checked mine on 40 meters and all is normal.  Output is the same for
ESSB on or off,  USB or LSB.  I used a mic plugged into the front of the
radio.

I thought the problem had gone away however I discovered I had the ESS
option turned off instead. I need someone to test this. You must be on 40
meters, LSB in ESSB mode. Compare upper and lower SSB power outputs. I see
about 50% power in LSB. When I whistle in the mic, the power jumps quickly
to 100w then quickly decreases to 50w. Not so in USB.

i also see the same problem. i thought that for some reason the TXGN HP setting was messed up. I checked this setting and confirmed it was ok. My K3 also shows the same symptoms on 40 meters.
