There were a number of changes to the rules agreed at the recent IARU Conference. The main change is that there are separate sections for single-location and roving stations. Also the band multipliers have changed. Full details here: https://storage.iaru-r1.org/index.php/s ... Conference
I have retired as IARU R1 ATV Contest Manager (after 7 years). I'll post details of my successor as soon as the name is confirmed.
