I've just installed two copies of VARA HF (Tx and Monitor) and VarAC on a Windows 10 PC connected to a K3S. I purchased a license for VARA and pasted the call and reg string into the Tx settings (the monitor's settings are greyed out).
However, I'm still getting warnings that VARA is in evaluation mode. Is this because the monitor VARA does not have a reg string? I suppose I could edit the .ini manually, but I'd like to check first.
