The ALC action in the Orions is not meant to be user adjustable. Not that
there isn't an adjustment, and if there is, I suspect it would be found in
the A5 section, schematic 81911_2 which is available on the RF Squared web
site. R179 is a power-set control, and R19 is unlabeled, but may effect the
ALC operation.

Since you do have a mic gain in the Orion, you might have a CW drive
control and can use each on the appropriate mode to minimize exciter ALC
action and so develop a cleaner signal, but without as much compression
punch that lots of ALC action also provides. I predict that if the CW
equivalent of mic gain is turned down until there is very little ALC
action that the clicks will go away and that the rise time will be that
set, not shorter.
