K3 SSB Setup?

Curt Knight
Aloha,

I built my new K3 SN 469 over last weekend and I have been having a lot of
fun with it on CW, but I'm still not sure that I have it configured properly
for SSB.  I have the latest firmware, I am using a Proset-K2, and I have the
mic input set for front panel, high gain, and bias on.  I have configured
the filters and I have done ref cal by zero beat with WWVH.

When I try to do the mic gain, compression, and ALC setting steps on manual
page 26, I find that while the ALC attack is very fast, the decay is very
slow.  So I speak into the microphone and get my 6 ALC bars immediately,
then it takes maybe 3-4 seconds for the bars to slowly disappear.  Is this
normal?  I haven't found a front panel mic gain and compression combination
yet that gives me what looks like a normal bounce on my power meter.  I must
be missing something in the configuration.  I haven't tried it on the air
yet; I will recruit some local help later in the week to give me a listen.

And concerning the ref cal.  I did get the 1 ppm reference, and I tried to
follow the ref cal steps on page 47, "method 3" but when I tap 1 according
to the instructions the display doesn't change at all.  Is this method not
implemented yet?

thanks,

Curt AH6RE

A number of people have commented about the (apparent) lack of average  
power with SSB processing in the present implementation. Wayne and  
Lyle, the firmware guys, have stated that they want to review current  
behavior of the processor and make changes as necessary.

Imho, the modulation is very good for casual QSOs but is lacking for  
contest situations. This is also the opinion of several other OMs in  
southern Germany.

Curt,
Tx SSB.This is normal. SSB tx signal from K3 is good
but I understand that in the future there will be some
improvement (firmware).
I have adjusted compresion to 25 and than  MIC
gain to the point that there is no distortion.
That way I can get more dynamic signal (good average
power). I'm using external receiver to monitor the
audio during this adjustment.
