The World of QRP The Fun of Low Power Ham Radio Loren C. Singh, AE7CG Prescott Valley, Arizona What is QRP? — Amateur radio communication using 5 watts or less — Any operating mode: CW, AM, SSB, FM, PSK31, etc. — Smaller, less expensive, more energy-efficient equipment — Homebrew, kit, or manufactured gear QRP in a QRO World — Work the world, 24 x 7 x 365? — “Life is too short for QRP!” — Develop operating skills: patience, skill, determination — Awareness of changing band conditions — Surfing: “Ride the wave of QSB” Results can be surprising!

I’m QRP.” “Well, THIS is what you sound like!” [QRO station decreases power to 2 watts.] “Sounds pretty good to me.” “Thanks for the QSO. I’m QRU.” “Sorry. No copy. You’re very weak.” “Your RST is 559.” “72” This presentation about QRP has just touched upon a few areas. Amateur radio should be fun, and QRP operation can open many avenues for joy, learning, and friendship. The world of QRP shows that the hobby need not be overly complicated, expensive, or beyond comprehension. More can be less, and simplicity can be its own reward — certainly ideas to be considered. 72 & 73, AE7CG .
