Hi ...

It's correct. XR9 (and SR9) uses a 2.4GHz chipset downconverted to 902 ... 928MHz.

There's a frequency conversion table for both, despite ROS shows the correct 900MHz frequency for SR9 (but not for XR9 that still using 2.4GHz notation)

2442 = 922MHz (5 & 10MHz channels)
2437 = 917MHz (5, 10 & 20MHz channels)
2432 = 912MHz (5, 10 & 20MHz channels)
2427 = 907MHz (5 & 10 MHz channels)

Left them at default power because if you use card rates there's some ghost signals 20MHz above and below the desired frequency, making clients try sometimes to connect to this signal, which is aprox -20dBc when compared to the main one.

Regards;
