QRP - Why Five Watts of Morse Outperform a Hundred Watts of Voice Amateur radio's low-power cult is not nostalgia; it is physics. A Morse signal concentrates its energy so tightly that milliwatts can cross oceans that swallow much bigger voice signals. Bandwidth is the secret Voice needs roughly 2,400 Hz of spectrum; a Morse signal needs about 100 Hz. The narrower the receiver listens, the less noise it hears - so the tiny CW signal stands out while the loud voice fades into static. The 5-watt challenge QRP operators cap their power at 5 watts and log intercontinental contacts as a sport. Their patron technology is the oldest in radio: dots and dashes, designed for a bad wire in 1844 and still winning on bad bands today.
