The SX1262… the radio range in the datasheet cover from 100 to 1000 mhz roughly. All available devices seem to be centered frequently on 433, 868 or 915.
I know there is a hardware and optimization aspect to have different frequency selected but other then that. What stops me from building a simple module that does an okay job any software selected freq even if not optimized for a specific band. And what is the compromise in terms of Sensitivity ? Radiated power ? 10% ? 50%?
