QRP Amateur Radio Club International


QRP ARCI is a club for low power enthusiasts worldwide.

We produce a professional quality magazine (QRP Quarterly), organize an annual conference at Dayton ('Four Days In May' or FDIM), and sponsor various QRP contests and awards.

Our aim is to promote QRP and a variety of related activites. Many of our members enjoy home construction, kit building, antenna experimentation, backpacking and portable operation. Minimalist radios built in small tins are very popular but we also enjoy the very latest high performance radios such as the Elecraft KX3, the new SDR rigs, and great kits like the QCX from QRP Labs, kits from 4 States QRP Group, and the uBitx rigs. 

QRP-ARCI is an affiliated Club of the American Radio Relay League

Let us know if we can promote your club, group, kit or product.
