I want to know how to record and play radio waves? I want to make a universal remote.I have an ir receiver and transmiter. I.I can use it to control my tv and other equipment.I want to also control my dish network in the US. I checked and think that the dish uses 395mhz but i am not sure.How can i replicate a dish remote radio signal.I know it is radio signal and not ir. What part do I need for the arduino?
This is only a partial answer, but should be enough to get you started.

The parts are:


Build a receiver http://www.somerset.net/arm/fm_only_lowtech.html
Tune it to the right frequency
Use it to detect the codes sent from your remote
Build a transmitter http://makezine.com/projects/super-simple-fm-transmitter/
Tune it to the right frequency
Transmit the codes
Success!


Step 3 is probably best done with a scope - you should find someone who has one, who can operate it, because they can be damaged.
