Traditional AM/FM radio is still around, but with a dwindling audience. The graph below, from online statistic site Statista, shows the average daily media use in the US over the past four years. Radio usage, represented by the green trend line, has been steadily declining.



Do radio stations pay for music?


Royalties and Radio:

Public performances generate performance royalties for songwriters, which are collected by the PROs (ASCAP, BMI, or SESAC). In the US, terrestrial broadcasters (AM or FM stations) do not pay performers or sound recording copyright owners; they only pay the songwriters.



How much power does a radio antenna receive?


For commercial broadcast antennas they use an array of vertical dipoles, so they won’t emit up or down, but mostly into horizontal plane. The antenna gain will be at least 2 or more, I assume 3x. So the field is likely about 0.7mW x 3 = 2mW/m2 at my location.



How many amps does a ham radio use?


That noise interferes with your ability to hear the other station’s signal. One place to go for them is Ham Radio Outlet—they have quite a few to choose from. Essentially, you want a 13.8 vdc power supply of at least 20 amps, because that’s what your 100-watt HF rig will draw on transmit.



How many watts does a CB radio use?


Although the FCC limits CB radios to a standard 4 Watts of power, there is an exception. If you want the best range, you may want a radio with single sideband (SSB) capability. SSB radios, such as the Cobra 148 GTL transmit at approximately 12 Watts, or three times the normal power.
