Problem resolved. I finally remembered how to tune the Vara HF Modem to the Radio. Had first VarAC QSO and several others today. Thanks.

Now that ICOM 9100 is controlling Rig, any ICOM 9100 Users with Filters and ALC Settings?

Sorry NOW controlling Rig! Problem solved Irad.

Looks like I had the wrong Com Port Selected. Looked at Com Port from other Digital Modes CAT Control and had wrong port by default for the ICOM 9100. Var AC not controlling rig! Thanks

Okay, thanks for the feedback. Will get back to you.

Have ICOM 9100 working fine with Vara HF. However, cannot transmit from rig with Vara AC. Perhaps ICOM 9100 Vara AC Users or others may have CAT control fix. Open to any ideas.
