The Army's SCR-300 backpack radio, also known as the "Walkie-Talkie," revolutionized communication during World War II. T/5 Harvey, a radioman with the 10th Mountain Division, used the radio in combat in Italy. Despite intense gunfire, Harvey managed to maintain his position and send out contact reports. The flexible attachment of the radio allowed him to maintain an upright position for better reception. The field telephone, relying on wire, was not portable enough for quick communication. The invention of wireless radios revolutionized communication during the war.
The U.S. Army Signal Corps began a design initiative to create a portable AM frequency radio, known as "Walkie-Talkies." The SCR-194 and 195 backpack radios were successful but heavy and had tuning and reliability issues. In 1940, Motorola-manufacturing company Galvin Manufacturing Corporation developed the "Handie-Talkie" SCR-536 handheld two-way AM radio. Engineer Daniel Noble convinced Signal Corps members that FM technology was better for their new radio. The SCR-300 was designed to be battery-operated, weigh no more than 35 pounds, and be water-resistant. The project was approved and produced two prototypes by spring 1942.

The SCR-300, developed by Galvin, was a portable radio designed for the Army during World War II. Initially limited to GIs, it was easy to operate and had a simple circuit called Automatic Frequency Control. The SCR-300 was crucial for communication between infantry companies and battalion headquarters, and was used by Army and Marine units in an island-hopping campaign against Imperial Japan's forces in the South Pacific. The radios were shipped to the infantry and other branches of the U.S. military, and Galvin employed a fungus-prevention technique to protect the electronic parts from moisture damage. The radios were shipped to infantry and other branches of the U.S. military, and replacement batteries were made a high-priority supply item. The ruggedness of the SCR-300 was largely due to its durable parts, such as the cable, rubber grommets, hinged seal covers, a strong steel outer case, and a compact circuit board construction.

During World War II, the SCR-300 radios were effective in combat, allowing battalion and company leaders to communicate instantly about tactical demands and operations. The "Walkie-Talkie" provided Marines with close-quarters firepower against Japanese strongpoints and caves. The radio set, developed by Galvin Manufacturing Corporation, saved many American and Allied lives. However, the SCR-300 radio could not connect to USAAF planes flying overhead due to the lack of FM modulated radios. Liaison radios, like the AN/ARC-44, were introduced in the 1950s.

*I'd love see a video or two on the operational side of WWII radio. What frequencies were used for what purposes? How did the Allies and the Axis deal with their signals interfering with one another? Were their gentleman's agreements that said, "We use 6.0-6.2 MHz and you get 6.2-6.4 MHz or was it a free-for-all? Did the two sides occasionally converse? The number of radio operators from WWII must be going down rapidly, so finding out first hand is important. I can add one tidbit. Hans von Luck's Panzer Command says that in North Africa they had an agreed on time and frequency to exchange the names of new prisoners. That spared both sides the burden of launching a massive search if someone went missing in the desert.*

The text at the bottom is inaccurate and more distracting than helpful.

Weird pronunciation of, of all words, antenna.

Clickbait, not about the radio, downvote.
