That's the most official-looking (free) source of information I could
trun up as well.
Dmitry, you site AS/NZS 4268 as your source - do you have access to
this, and can you confirm that the requirements are closest to DFS-ETSI?
It would be great if someone else with access to the document could ack
this as well, since at first blush this appears to be in contradiction
to Peter's email.
I agree that it doesn't seem to make any sense for Australia and New
Zealand to be different here. So if Australia is specified to use
DFS-ETSI I think New Zealand should be changed to use it as well.
Thanks,
Seth
