The World of QRP

The Fun of Low Power Ham Radio

Loren C. Singh, AE7CG

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!

“Please increase your power.”

“I can’t. 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.
