The 1000D is pretty slow in fast AGC also. In the 1000D, there are 
two parallel capacitors that appear to set the AGC recovery time on 
fast. I tried removing one of the capacitors, but it made only a 
small improvement. Someday I'll look at that again, because it sure 
hampers receiving weak CW during static bursts with the fast AGC 
being so slow.73, Tom W8JI
