Default Spektrum Air Module Output Power

Dany, hi

I believe some countries have a limit of 100mW on the output power of DSM transmitters (that must also include modules I presume) and the likes of the USA allows 1W output. Is there any way of telling the TX output of my module other than putting it on an RF watt meter. I can't seem to find any info in the manual.

Thanks.

As he listens to the Mission Impossible theme music !

Good Luck to you, it seems to be a closely guarded secret. I have asked Paul Beard through unofficial and official channels to see the actual test results for the European standard....... still waiting..

You could check the relative RF output yourself if you had access to a microwave RF power meter at 2.4 GHZ. Keep in mind that the connection between the DX-7 and the meter would have to be minimized due to high losses in cable and connectors used. I would be interested in knowing the results of any measurements. I personally do not see how RF output is not relative to range calculations. If it were between 100 and 200 milliwatts, the 100 MW difference just between those 2 outputs would be a difference of 3 Decibels in signal strengh and a significant difference in signal strength at the receiver.

Range is far more dependant on other factors such as the installation in the model. Regardless, range of the system is line of sight.
