Private aircraft in the USA are not required to have any radios for VFR flight into uncontrolled airports. Aircraft voice communications are in the range from 118 to 137 MHz.

Aircraft radios have different requirements than marine radios do. Because they tend to operate well above the ground, they transmit in a frequency band that is "line of sight" limited. From 30,000 feet your line of sight can cover a significant distance, allowing communications at great distances.
Ships on the ocean do not operate this high, yet still need to transmit long distances (up to thousands of miles in some cases) For that reason, a lower frequency band has been designated for oceanic communications. These radio waves tend to bounce off the water, then off the upper atmosphere, and then back, and so on until reaching their destination.
A similar frequency band has been designated for use in AM radios. You can tune an AM radio to a station hundreds or even thousands of miles away and (especially at night) receive a transmission. HAM radios work much the same way.
The spectrum of radio signals is literally infinite. Every wave pattern has unique characteristics. The spectrum has been segmented up and designated for specific uses for a few reasons. One is that certain frequencies are just more useful for certain applications (One of the downsides to those low frequency transmissions is a slow transfer rate...imagine sending an email that took 15 minutes to be sent). And in other cases they are differentiated simply to prevent frequency crossover. FM radios and Aircraft navigation signals transmit on nearly identical frequencies, but there is a clear delineation between them to prevent airplanes from accidentally homing in on radio station (incedentally some airplanes can and have done this to AM stations) rather than on the appropriate navigation facility.
As far as what's required...aircraft are not actually required to have any radios at all. They are very limited in where they can go without radios, but you dont need them. The requirements are the same in Mexico as they are here.

The requirement of radios is determined by the intended operation. Any airspace where communication is required, you must have a radio. All civil aircraft operate on the same frequency range as mentioned above. Marine is different.
If you are flying across the border you need to get a radio license.

For flights in Mexico, you are required by the FAA to obtain a Third Class Radio License

Radio stations for music use AM (Amplitude Modulation) and FM (Frequency Modulation) I uncertain, yet, I thinking Boats and Airplanes the two use VHF (Very intense Frequency). yet, they are in distinctive frequencies stages, this may well be for FCC rules. i will look some greater, yet, one may well be changed to Transmit and get carry of on the frequency of the different. Say, regulate the Boat Radio and the plane no longer choose something. it is greater low-value to in trouble-free terms purchase a boat Radio for the plane or vice-versa.
