That number is the 'frequency' of the radio waves transmitted by that station ...the number of times the wave wiggles in one second. "102 megahertz" means102 million every second.Right now, in your room and in the air around you, there are thousands of radiosignals from AM and FM broadcast stations, police cars, taxis, ambulances, cellphones, airplanes calling the air-traffic controllers, TV stations on the groundand TV satellites in space, GPS satellites, and RADARs watching for rainstorms.The only way your radio is able to pick out the one you want to hear and discardall the others is to separate them according to their frequencies. If there arefour radio transmitters all close enough to you and all on the same frequency,then your radio can't separate them, and you hear them all at the same time.That's why there are never two TV stations in the same city on the same channel,or two radio stations on the same number.
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the signal.
Each note has a specific frequency. The frequency is defined by the wavelengths produced by the sound. Just as FM radio stations each have specific frequencies (ie: 96.5), musical notes are the same. Think of an image of a wavelength. The more squiggles, the higher the frequency, and the higher the pitch.
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
AM = amplitude modulated. FM = frequency modulated.

if the 103 is the radio station is 103, that means it is broadcasting with a wave frequency or 103 megaHertz provided it is an Fm station. If it is an AM station, then it would be 103 kiloHertz.

RF = Radio Frequency
49 mhz means 49 megahertz, which is a measure of frequency in waves. What this mean is that the wave form repeats itself 49,000,000 times each second.
Radio Frequency Identity Tags.
This would mean the operating frequency, in hertz or megahertz of the chips in the random access memory. Common values are between 100mHz and 800mHz. Newer computers generally have memory frequencies of 400mHz or more.
FM means frequency modulation, and AM means amplitude modulation.
