Are we limited in range by sensitivity or by noise?
At 72mhz, both man made and atmospheric noise can have an effect along with receiver sensitivity. There are also other specifications which all play a part.
I am a bit confused why transmitter and receiver manufactures don't publish specifications on their equipment. At least I have never seen any. That way we can compare receivers and transmitters intelligently.
I would also like to see an article that compares receiver specifications. And then puts the receiver and transmitter on test equipment and report the findings. I hear guys often mention that one type of receiver works better than others especially in these domes when there are a lot of electric flyer's, flying in close to each other. Lets see some real specs!
