It looks like superchannel is available free of charge since v4.3, or maybe I’m getting old and have forgotten that I purchased superchannel licenses for all my routers.
yes, it is.
That is great news. 
Thanks Mikrotik.
Don’t need to buy more superchannel license.
Too bad 4.3 hasn’t nstreme stable 
where or what is this supperchannels?
It’s called “Compliance Testing Mode” and allows you to use any frequency that your wireless card supports. This usually means 5Mhz steps from ~4.9 to ~6GHz and from ~2.3Ghz to ~2.6Ghz
This mode should be used either in controlled environments, for testing, or if you have some special permission from the government to use non-standard frequencies.
All my 2.4 GHz card I tested so far goes from 2.192 - 2.539 GHz.
ok, probably you are right
No, I wasn’t correct. I found one card that goes from 2.312 - 2.732.
It’s the same chipset, but another maker.
Thanks for the great news.
Normis;
Could you guys do this for v3.x aswell ? I need them for my CPEs so badly.
Normis…
Is the truth the Nstreme is not stable in V4.3?
How about V4.3 with R5h, the wds configuration remain the same?
Excellent
/me goes to upgrade
