Molecules in the retina respond to particular wavelengths of electromagnetic radiation - what we think of as visible light - and this is how we can see. Insects can see further into the EM spectrum than we can. Is it conceivable that an organ could evolve which has molecules, crystals or whatever that can transmit and receive radio wavelengths?

Is it possible? Maybe. Is it probable? Not at all.
The problem is that to evolve, a radio wave sense would have to start from somewhere and be useful somehow. Eyes started with light-sensitive cells, but I'm not aware of any radio-wave-sensitive cells at all. Such cells may not even be possible because of the wavelenth. Radio waves would also have to convey some useful information so that such cells - if they appear - would be selected for. Aside from human-made radio broadcasts, that is not the case. Unlike light, radio waves are practically useless for getting relevant information about the environment. Transmitting radio waves would obviously be pointless before there was something to receive them, so you'd need a receiver organ first.
All in all, I don't think radio wave sense would ever evolve naturally in any Earth-like environment, simply because it wouldn't confer any survival advantage in the early evolutionary stages.

With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people. I start getting more concern about my future as well as my family after watching the response of our Government for the people that affected by hurricane Katrina.
According to recent studies made by World Bank, the coming crisis will be far worse than initially predicted. So if you're already preparing for the crisis (or haven't started yet) make sure you watch this video at http://www.familysurvival.tv and discover the 4 BIG issues you'll have to deal with when the crisis hits, and how to solve them fast (before the disaster strikes your town!) without spending $1,000s on overrated items and useless survival books.

advantageous it extremely is as others have pronounced besides the reality that a minimum of one have been given the order incorrect. The electromagnetic spectrum going from longer wavelengths to shorted is going Radiowaves > Microwaves > Infrared > considered ordinary (pink-violet) > Ultraviolet > X-rays > Gamma rays. they're all composed of photons. As somebody else pronounced there on the instantaneous are no longer any sparkling divides between them - the diversities are human labels - no longer some thing greater - to make the element, evaluate that distinctive animals have distinctive barriers on what ordinary is considered to them - many birds and bugs can see extremely precise in to the ultraviolet and have coats and markings that take place under a blacklight.

Sure, why not? Bats have evolved sonar. From a practical standpoint, in terms of the length of resonant antennas, I think the radio waves would have to be microwaves. I believe pit viper snakes have pits which are sensitive to infrared radiation, so your idea is not unrealistic.

I think so....people have been known to pick up radio stations with their braces !!! a long time ago...remember....when kids had LOTS of silver in their mouths ! Our ears would have to "adapt", but , I think humans are going through changes as a species right now. Something is happening. Kids are bigger and smarter than even 30 years ago. And, there is a lot of "unused space" in our brains. Maybe we have a long way to go as humans. But, in reality, I think you are on to something.

Well, kinda.
Radio wavelengths get so tremendously big, that there is very little reason for animals to use them
Whales need to communicate over long distances, so it would be useful to them. But beyond that, it just wouldn't be any advantage for most animals. So not subject to evolution.
