AM is not near as good as FM and is plagued by all the electrical noise that would make it almost impossible to listen in your home with a weaker signal. Also an AM transmitter is much more involved to set up. To get the distance people get here on the forum you have to have a house with your own property or large backyard to have an outdoor antenna and you have to dig up half the yard to install the buried radial wires. The antenna and loading coil is more complicated too..
Well, that is true.. to an extent.. but broadcasting AM is not nearly as bad as you make it sound. First off, if listening just in your home in the general vicinity of your transmitter the sound quality is going to be excellent, and electrical noise will actually be pratically non existent as long as your within say a block radius of your transmitter.. then as you get farther away then electrical noise can become gradually more evident..
As for an AM transmitter being more involved to set up.. Again, that’s only partially true.. It can be as simple as applying power, using a basic wire antenna, no ground, set the transmitter on your desk, insert audio and begin transmitting.. With such an install you will most likely exceed the legal range of a part 15 FM transmitter.
Setting up an AM transmitter only becomes an more involved proccess when you decide you wish to improve the performance with a more elaborate install involving a more advanced grounding system and/or antenna system.
If you want to be able to broadcast legally farther than 200 feet (in the US), then choosing AM over FM is a no-brainer.
