[Elecraft] SSB output overshoot

G'day,

When I run the K2/100 into my Acom 1000 I usually set the requested power 
to about 30 - 35W.  I seldom drive the amp more than 400 - 500W output.

On CW all is fine but on SSB I notice there is a severe overshoot on the 
output for the first syllable after changing to TX and after a few seconds 
pause in talking.  With the K2/100 barefoot at 30W requested, on CW the RF 
bar is steady on 3 but on SSB it overshoots to 4-5 before settling at 3. 
At present the K2 is set up as twins with the KPA100 co-located with the 
KAT100.

Anyone else noticed this?  It would be interesting to put a scope on the 
output to monitor what happens to the RF level, unfortunately I don't have 
one.

On 40M SSB problem is particularly severe, CW no problem.

Regards,

Mike VP8NO
