No, he did not, but he was certainly important in radio's growth and development. Edwin Howard Armstrong invented what we today know as FM radio. (Early radio used only the AM process to add sound to a radio wave.) Armstrong's invention improved the quality of the sound and made radio less likely to be affected by static.
FM broadcasting is a broadcast technology invented by Edwin Armstrong that used Frequency Modulation (FM) to provide high fidelity sound over broadcast radio
The FM radio was invented in 1933. It was invented by the inventor Edwin Howard Armstrong. He invented the frequency that allows radios to work.
According to a recent book (Early FM Radio, by Frost), modern FM wasn't invented all at once, but evolved with the help of dozens of other people besides Armstrong. But Armstrong was the first to significantly widen the frequency swing. A hand-drawn sketch indicates that he hit on that idea in the summer of 1932. During the following January he filed two patent applications for wide-band FM, one of which has a similar sketch. On December 26, 1933, he was awarded four patents for FM radio (The other two were applied for in 1927 and 1930, but weren't for wide-band). He discovered in early 1934 that his invention was almost free of static.Armstrong took a few more years to give FM high fidelity, but by 1938 or 1939 he had improved FM to the point that it was our FM radio, minus the stereo sound.
AM radio is KHz FM radio is MHz AM radio can cover the world. FM radio can cover a county. AM radio is excellent in communication. FM radio is completely worthless, except for good sound quality. AM radio doesn't have as good sound quality as FM. FM is much higher on the radio spectrum than AM.
Edwin Howard Armstrong invented several things, but he is best known for inventing what we today know as FM radio. (Early radio was only on the AM band.) Armstrong's invention improved the quality of the sound and made radio less likely to be affected by static.

he did not invent anything but he was the first man to land on the moon

A radio that receives Frequency Modulated (FM) transmissions.
The main difference between AM and FM radio is the dial-in number and the amount of static each receive. AM radio preceded FM radio, with FM becoming popular in the 1950s.
Frequency ModulationFM broadcasting is a broadcast technology invented by Edwin Armstrong that used Frequency Modulation (FM) to provide high fidelity sound over broadcast radioFrequency Modulated and Amplitude Modulation :) The way a signal is transmitted.
One of the main differences between satellite radio and FM radio is that there is a cost for satellite and FM is free. Satellite radio also does not operate using the same numerical AM and FM channels as FM radio.
