Spectrum Radio
Has anyone systematically searched for animals that "see" outside the spectrum we see?
To find out whether any animals can see way outside our spectrum, like radio waves or something. Please include links so I can read about it.
If you're talking about actual "seeing" rather than just detecting infrared (like pit vipers) or subsonic (like elephants), do a search for bees. Bees' vision is shifted slightly toward the shorter wavelengths, so they can't see red, but they can see ultraviolet; this shows up in the way some flowers are colored, with "honer guides" only bees can see.

How is the radio spectrum used?
The more info you give the better chance of you getting best answer.
Key Points About Radio Spectrum
* Radio communications use radio waves at different frequencies, grouped within bands, that are part of the radio spectrum.
* The Federal Communications Commission (FCC) regulates use of the non-Federal spectrum, including that used by State and local public safety agencies.
* The spectrum is an increasingly scarce resource, and public safety competes with commercial interests for this resource.
* Most recent spectrum allocations intended to help meet increasing public safety spectrum demand include parts of the 700 MHz and 4.9 GHz bands.
* Narrowband channel migration will increase efficient use of the current frequency allocations.
Radio spectrum
The complete range of frequencies from approximately 30 kHz up to more than 300 GHz that can be used for radio communications. Frequencies are often grouped in ranges called bands. Bands of interest to public safety include HF (high frequency), VHF (very high frequency), UHF (ultra high frequency), and most recently SHF (super high frequency). Radio systems operating in the 806–824 MHz and 851–869 MHz portion of the UHF band are often referred to as “800 MHz systems” and are distinguished from systems in the other parts of the UHF band. Frequencies above 1 GHz are often referred to as “microwave” bands. A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies within a specific frequency band (or bands).
Spectrum Allocations/Regulations
Spectrum allocations for State and local public safety are fragmented into many distinct slices of the radio spectrum. Regulation of specific frequencies for Federal agency use occurs within the National Telecommunications and Information Administration, while the FCC regulates the spectrum for non-Federal users.
