The new Alpha 8100 likewise has no connection for ALC input.

Quoting from the manual for the Ten Tec Titan 425:
"Today, most solid state transceivers provide no connection for ALC input
and it is entirely unnecessary to make any external ALC connection to
these rigs. The ALC input jack is used primarily with tube-type
transmitters/transceivers having a negative going ALC system."
The Ten Tec Hercules II has NO connection for ALC at all.
Indeed, I've seen comments from "authorities" saying that using ALC is
more likely to INCREASE splatter, because it doesn't kick in until the amp
is overdriven.
I've never used ALC with my Titans, and the serious contesters near me
tell my signal is clean. I've use an Omni V, TS-850, and FT-1000MP with
them. I DID get complaints when I drove a Titan with a K2/100, because
that transceiver has more phase noise on transmit. My neighbors don't
notice it at 100 watts, but they do when it's amplified 12 dB. I'm told
the new K3 is MUCH better in that regard.
