HAP AC3 Super Channel WiFiWave2 Not working

Can’t set the Wifi1 interface to super channel, I set it to the Desired frequency but there is no no_country_set under the Region Selector which lead to invalid selected channel.

I need it for firmware testing, and I am legalized for it

I’m using 7.8 Router board and Wifi Wave 2 version on the Mikrotik HAP ac3

Just to be clear: 5GHz channel on AC3 = wifi2

What super channel do you refer to ?
80+80 or 160 on 5GHz ?
AC3 uses IPQ-4019 and that chip does not support channels wider then 80MHz

I want to set it to 2.3~ superchannel frequencies

Maybe best you first clarify exactly what your understanding is of superchannel and for which frequency.
As specific as possible.

2.3 is an odd frequency.

No wonder you don’t know! ;-PP

Your device does not support these frequencies only 2.4GHz

Already said so in the first answer…

Mikrotik has older devices that support a wider range of frequencies
