I can easily configure freq of module between 430 - 500 MHz.
Used and suggested registers values as above which is succesfully working:
0x07 => 0x6c //434MHz
0x08 => 0x80
0x09 => 0x00

But When I set the registers according to 915 MHz.Module Cant Trasmitting.I do not see anything in the frequency analyzer.
0x07 => 0xe4 //915MHz
0x08 => 0xc0
0x09 ?> 0x00

I do not change anything except the registers above when I change freq. from 430 Mhz to 915Mhz.
What is the reason for this?
Could it be related to the antenna?
