I've just started using VaRAC and it is a really great mode as I have been searching for a Keyboard to Keyboard mode that was like my favourite old AMTOR back in the old days.
I'm using a Hermes Lite 2 SDR and it appears to working fine, but I wanted to ask what people do about filtering? At the moment I have one filter set at 600 Hz to give a bit of leeway in case tuning is a bit off.
Do people use a wide filter when monitoring the calling frequnecies and channels either side and then switch to narrow or am I overthinking it?

Have set up VarAC on my Hermes Lite 2 and can receive OK but have not yet tried a QSO and would like help on my filter settings.
There are two places to set filters for DigU and I am a little confused. I have added screenshots of the Offsets and also as an example the settings for a 600Hz filter. I think they are the default settings but would appreciate any help in getting them optimised.
Also when I set the ALC to 30% I have no output power. Unless I set the ALC at 0db I do not get the full power out (5W)
