[Elecraft] Fw: ESSB

Try to make me understand why you would use ESSB

Using several different K3 and P3 combinations in over the air test, it
appears that when running the K3  in ESSB mode and set to 3KHZ the actual
bandwidth for a full audio range SSB signal is about 3.5 to 3.6 KHz in
width. Set for 4Khz the bandwidth is about 4.6 Khz.  If this is not true
then it appears that the P3 is improperly showing the bandwidth.  In all
the test the K3 receivers were set a 4 Khz  bandwidth. 
 
These same set ups show the standard 2.8 Khz k3 signal to be 2.8 Khz. 
 
Can someone with a white noise generator and a good spectrum analyzer
take a look at a K3 in ESSB mode. I dont want to be using ESSB if I cant
limit my signal width to 3.2 Khz.
When listening to the 2.8 vs the K3  in ESSB set at 3khz there is far
more difference in the quality than I think there should be for just 200
cycles more in bandwidth width the same audio input. 
 
Hope to have someone give it a try and report. Thanks Van W4GIW
