I built a telemetry pair for a friend. An idea I used to have for a really long time, but I had lack of interest to do it only for myself.
All the system is based on arduino pro mini and NRF24L01 Transceiver module. (on the very beggining I had problems with the code on the atmega328 on the TX side and so I was forced to use atmega2560 for TX which was quite heavy for that application. After the code optimized runs fine on the atmega328)
The data that is transmitted at this point :
Speed (km/h)
Altitude(m)
Temperature (internal) (Celsius)
Battery Voltage of the battery of the plane (up to 4s battery) .
Here is on the field test
I am interested in increasing the range of the system , so will need a different TX/RX module instead of NRF24L01.
Can you suggest me a more powerful data link pair ?

What range have you got now and what range do you want?
Have you considered the high-power nRF24s with the external antennas?
Hello, the maximum range I have reached using NRF24L01 + PA + LNA is 2kM line of sight with stationary modules , in the wilderness.
In a moving airplane i have reached so far 1kM LOS but did not reach the limit of the range.
The range that I want is 10kM but i do not need high data rate or transceiver modules (just a transmitter and a receiver)

Actually is 1km not 2.

Lower frequency devices tend to have longer ranges. Directional antennas can also make a big difference - but they are probably only practical for stationary installations.
My guess is that your requirement for 10km range will be difficult to meet with wireless equipment that does not require a licence.

Licence? ow come on, yes I know you need to have one to use the device..etc but u can build our own
station that can get up to 10km of course you will be in trouble if you get high at 10km without a FAA
permission or even without permission will be your own risk if a commercial airplane will fly around.
As I know this guys are from greece and in greece there is many places that you can fly without
licence or permission, they got high mountains and non of commercial airplane fly close to mountains
and they can get 2km without any risk getting in trouble or because they don't have licence.
yes I know you need to have one to use the device..etc
I already explained more than needed
But I don't think you need a licence to use a standard Radio RC Airplane module/controller you can modify it
and a parabolic antenna/reflector a better antenna and you get from a cheap 20$ 1km radio up to 3~5km.
I want to make an arduino telemetry system that will send me data from a plane and for example if my speed is over lets say 50km will activate a mp3 file that will say "Over Speed" and so on. can you show me the code and explain how you made it. Whore you able to get a better distance?
