Dave,
Haven't used it on mine, but your numbers don't match this guy's,
right? You cant get the ALC to activate at all?

Something might be wrong...
Also I *seem* to recall somewhere in the dusty corners of my mind that
there's a menu setting that swaps the ALC pin from being an ALC to
something else... seems like it was a toggle...
There seems to be more "chatter" out there about ALC modifications to
the FT-847 since I last looked on Google. Stuff like this:

Did you buy yours used, or have you had it since new? Someone may have
dorked with it.
