After a week still no sign of channel 701 again, so maybe they did make a mistake with the countries planned for accessing it.
If it turns up I'll try to remember to edit that in, since few will be interested.
Either they're trying to fix this now, or there's other problems with 701 itself.
Overnight there were some very weird issues going on with the service, and this morning I found 701 had been removed. (Haven't checked if it's back.)
(Info in advance - those who can't find it in the future, it may instead be 'cos you're not set up for Hi Band.)
Channel 701 (from Mozambique) is new and correct, was "announced" by Thinus (in the press). The rest are very likely as you describe, a bad technical glitch when they enabled 701.
