[Elecraft] [K3] receive on ssb--DSP problem?

[Scott Monks]

Hi all, 

    I think I am going crazy -- vacation starts Saturday and I will have time to play with my K3 and now it is taunting me!

    I know there have been discussions on loss of receive on SSB, and now something like that is happening to me, but different!  


    I was making some contacts on PSK and went back to CW and SSB to see who was on.  I tuned in a SSB signal that I could see on the P3 screen but the receiver was completely silent.  I switched the mode down to CW and I could hear sounds.
    I figured the software might have gotten corrupted so I reloaded everything--no change.  I have the 2.7, 2.1, 700 and 400 filters--checked with the K3 software and all are activated as given.


    "Playing around" here is what I observed:
-If the DSP is opened to 3.20 the SSB sound comes through normally.

-If a narrower DSP setting is chosen (i.e. 3.0), the sound level drops way down,and at narrower settings (2.7 to 2.1) it goes away (no even background noise or hiss), but if I open CONFIG to CW QRQ and turn it from "off" to "on" to "off" again the sound will come through normally.  If I even touch the Width control at this time the sound drops way down again until I open the DSP to 3.2 again, but this time the sounds are coming thru a "tube".  If I switch to a different band and back again, sound is restored normally at DSP 3.2.

-it is the same with LSB and USB.

-the S-meter is active when the sound is reduced.

-Everything "appears" normal except there is very weak sound on SSB!

-things such as VOX, AGC, etc., do not seem to affect it.


    CW seems to be working normally.  I had been trying to get the APF to work, and now it does (I didn't understand how to turn it on!), but since the above started I went back and checked it to make sure I had not messed something up.  Having Dual PD or APF set does not affect the SSB situation.

Ok, I put a lot of background so maybe it would help make it clear what is happening.  If anyone can give me suggestions or criticize what I might be doing--please, all comments are welcome.  I just want to get things "right" again!

Thanks and 73,
