VarAC - HF discussion forum

I have read: We can use two instances of varac one in hf and another in vhf but some users not are active all the day or weekends. but the idea is report those users to the hf via the main station who is active full time. This is because one user not always is a person, it can be a entity with callsign who opens on office times and use local radios like vhf uhf.
