Adjusting Frequency by 0.2 MHz

Dear Renzo Mischianti, I am developing a product using the E220-900t22s LoRa module, and I have been greatly benefiting from your writings. Thank you for your continuous help. I need to use frequencies such as 922.1 MHz, 922.3 MHz, 922.5 MHz, etc., but it seems that the current program only allows setting frequencies like 922.125 MHz, 923.125 MHz, 924.125 MHz, and so on. Is there a way to perform more detailed frequency adjustments? #define DEVICE_CHAN (72) // Communication channel 0x48(72) 850.125 + 72 = 922.125 MHz
