If I set a CM9 or an SR5 to a tx power of 1, will they transmit at 1 db?
Yes, you will get such output power.
I can set it to 1, but will I actually get 1 db? Someone on the Part 15 Mikrotik list pointed me to a post on here talking about how the Atheros chipsets have a relative tx power field vs. an absolute field. IE: If 10 happens to be 10 dbm, then 15 is not 15 dbm. What’s the lowest I can go with these cards? I’m trying to find a way to use high gain dishes in the 5.250 - 5.725 bands.
Also, will Mikrotik release the requirement for the special frequency license for 5.4 GHz now that it is in\has been released in the US?
