How far you wanted to communicate? Mostly people using 433~900mhz 3DR/Sik radio module (air + ground module). You might wanted to check sample of my schematics setup at my website where i always keep my plane communicate with the ground beyond 13~15km here: http://www.supermotoxl.com/FPV/UAV-models-builds-and-flight-reviews...
we want that drone will coverr 12km distance from base station..so which transreceiver will be capable for this task....and
can u tell us abt specifications of the module
I use this one: http://www.banggood.com/3DR-Radio-Telemetry-Kit-433MHZ-for-MWC-APM-... but you need to do some DIY di-pole antenna for 43mhz
Here the sample of my video using this module transreceiver over 12km straight line: https://www.youtube.com/watch?v=6ORJgMfvUxc
is it compatible with PC..??
