    I have tried to find a list of what frequency each channel are using or is it the same frequency and just different channel for MySensors?
    I know it is 2,4GHz.

      Here is what I found from a Google search:

      The range is 2.400 to 2.525 Ghz which is 2400 to 2525 MHz (MegaHz). The nRF24L01 channel spacing is 1 Mhz which gives 125 possible channels numbered 0 .. 124.

      Source

      I can not guarantee that this source is reliable but it seems reasonable.

          @mfalkvidd
          Thanks

          #define MY_RF24_CHANNEL X, where X is the number to the left below

          0 => 2400 Mhz (RF24 channel 1)
          1 => 2401 Mhz (RF24 channel 2)
          76 => 2476 Mhz (RF24 channel 77) standard
          83 => 2483 Mhz (RF24 channel 84)
          124 => 2524 Mhz (RF24 channel 125)
          125 => 2525 Mhz (RF24 channel 126)

          Below is the Control Channel for WiFi and frequency.

          12, 13, 14 not available in all countries

          1 GHz = 1000 MHz
