[Fwd: Re: [Elecraft] ESSB Problem 40m]

[Ken K3IU]

Hi Steve:

I just did the following test and got  the same output from USB and LSB. 
Using latest beta firmware. K3 #202. Filters: AM; 2.8k; 1.8k; 400 Hz; 200 Hz

ESSB enabled - 4.0 Bandwidth
Band - 40 M
Mic set at 12
Comp set at 24
Power set at 100
Mode LSB
2 Tone - ON
Tap XMIT
Power out to Dummy load indicated on Diamond SX200 power meter - 80 watts
Switch to USB
Tap XMIT
Power out - 80 watts.
2 Tone - Off

Using a mic (Heil/Elecraft Pro-Set) plugged into back panel, the output 
on both sidebands appears approximately equal as best I can tell. 
Whistling into mic produces about 100 watts, both sidebands.

No problem here like you describe.

73,
Ken K3IU
