Cloth patch featuring a design of the official flag of the American Radio Relay League (ARRL). Size 4'' x 2.5''.

The ARRL flag was adopted in 1980 based on a design by Ralph Holberg, N4RX. There are 15 horizontal stripes, red and white, and one vertical red stripe at the hoist, all suggesting the stripes of the US and Canadian flags. The horizontal red stripes spell “QST” in Morse code, a “dah” stripe being three times as wide as a “dit” stripe.
