Agree with Marco. Variable levels per mode.
The original poster, Pietro, referred to VHF as a band, and I phrased my answer to basically say "It will do what you want it to do between HF and VHF"
Mode-based levels have come in handy for me on both my 817nd and my 897d. DIG level on HF ssb, PKT level on VHF/UHF pkt pkt9600 mostly.
