I may be confused, but I think that this week the only places in the vicinity of which VHF radio must be carried and used are 'registered' or 'certified' aerodromes.
Northam isn't registered or certified.
There are plenty of places that are marked as aerodromes on aeronautical charts but aren't registered or certified.
If you think everyone in the vicinity of a place that's marked as an aerodrome on an aeronautical chart has a radio, please think again and check ERSA.
