The K3 does have ALC output, but you shouldn't use it.  Using ALC on
any amplifier, with any rig will usually cause transmitted signal
problems.

Just tune the amp with the recommended drive and put it on standby
when not using it (don't forget to reset the power if you turned it up
after tuning).

I use an Alpha 87A and have never used the ALC on it in the 7 years
I've owned it.  Alpha recommends that it not be used.
