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.
What else can I help you with?
Did Edwin Armstrong invent the radio?
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.
When did Edwin Armstrong invent radio?
Edwin Armstrong did not invent radio, however he invented several improvements to radio.1913, the regenerative circuit (making oscillators possible, making the earlier sparkgap radios obsolete)1917 to 1919, superheterodyne radio receivers1921, super-regenerative radio receiversmiddle 1920s, frequency modulationEdwin Armstrong received 42 patents in total.
Were radios invented in 1914?
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.
How did Edwin Armstrong invent the FM radio?
Edwin Armstrong invented FM radio in the 1930s by developing frequency modulation as a method to improve audio quality over AM radio. He discovered that varying the frequency of the carrier wave, rather than its amplitude, reduced noise and static interference, producing clearer sound. His work involved extensive experimentation and the creation of the first FM transmitter and receiver. Armstrong's innovations laid the foundation for modern FM broadcasting and significantly advanced radio technology.
Who discovered FM loop?
The FM (Frequency Modulation) loop was developed by Edwin Howard Armstrong, an American inventor and electrical engineer. He introduced frequency modulation in the 1930s, which significantly improved the quality of radio transmission by reducing static and interference. Armstrong's work laid the foundation for modern FM radio broadcasting.
What did Edwin Armstrong invent?
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.

Did Edwin Howard Armstrong win any prizes?
In 1917, he received the Institute of Radio Engineers Medal of Honor. In 1919, the French government gave him the Legion of Honor. In 1941, he received the Franklin Medal. In 1942, he received the AIEE's Edison Medal.
Who made the radio and when was it made?
Guglielmo Marconi is credited with the invention of the radio in the late 19th century. He successfully transmitted radio signals across the Atlantic Ocean in 1901, marking a significant milestone in the development of wireless communication.
