The output power of the XPS RF modules is 100mW EIRP.
The over-air system that the XtremeLink system uses is unique from all others, It uses 5MHz of bandwidth for its spread spectrum transmissions. Spektrum uses 1MHz. Futaba uses 100KHz. JR DMSS uses the exact same over-air system we do (it was adopted by JR), but the packet data is different.
You can program the settings of any of the XtremeLink products using the XDP.
Your assumption about the power difference is incorrect. -30dbM to -22dBM is 8dBm, every 6dBm is double the power output. Our system is 100mW EIRP, and Spektrum is 200mW EIRP. You have to be measuring the power output at the antenna connector to determine the true output power. Antenna angle itself can reduce the range to nearly 0%. Point the tip of the antenna at your spectrum analyzer and you will understand what I mean. It's difficult to try to determine much from a simple analyzer just holding a transmitter.
As stated previously, receiver sensitivity is what determines the range. A built-in (PCB) antenna is probably in the -89dBi to -91dBi sensitivity range, maybe less. Our Nano receiver is -102dBi and the RFU is -107dBi.
