Hello All,
I have the Band decoder working and now
working on the ALC , it seems to work , but it's slow to react , Is this normal??
The Amp goes to 1200 watts at first then back to 840 watts ???
Thank everyone for all your help.

Yes, it's normal.  The K3's External ALC is slow acting, but the
Quadra's output WILL settle down to 1000 watts provided you have
calibrated the Quadra's ALC for 1000 watts output.  This will vary by
band, but as long as the variance results in an output of less than 1000
watts and not more, you're ok.  The receiving station will not notice
the difference.

On CW the slow-acting ALC is not a problem.

On SSB you will want to make sure the MIC gain is adjusted so you aren't
over-driving the Quadra.  Depending on your microphone, a MIC setting as
low as 2 may be normal, with minimal if any compression needed.

If you haven't yet looked at them, you might want to read two documents
on the N0SS website . . .

Let me know if I can help further.
