How to Change frequency

I have BH modul of P9 series with 2.4 mhz frequency but it’s frequency changed to 5.7 mhz so i want to change the other modules frequency to 5.7 mhz

please help me :?: :oops:

are you saying that a 2.4 radio changed itself to a 5.7?

are you sure the 2.4 isnt actally a 5.7 and just mislabeled? ie have you ever used it in a 2.4 link?

No My P9 radio is dual band so it can be changed to 5.7 ghz , it is not mislabeled

Dual 2.4 and 5.7? This can not be, the antenna and the radio are different.
