About our Kits - -

4SQRP designs are the result of thousands of hours of engineering time in service to the QRP community.

We pride ourselves on having the most unique and original kits available anywhere.

We make full design documentation freely available on our website as a service to builders and experimenters.

We do ask that if a design is borrowed for use in a kit or in a publication that proper attribution is made to the original designer.

About our History - -

The Four State QRP Group was formed in 2003 for the purpose of promoting the operation and construction of ow power amateur radio equipment. Incorporated as a non-profit organization, there no dues for membership. Rather, operating expenses of the club are generated through sales of QRP radio kits, which are designed, kitted, and sold by club volunteers to fund our annual conference, OzarkCon, which is held in Branson, MO each April.

Originally, the Four State QRP group was comprised of members residing in the states of Arkansas, Oklahoma, Missouri and Kansas. There is no regional requirement for membership though, and today, we proudly claim members from across the US and many DX countries. The original 4SQRP name has been retained due to its worldwide name recognition.

As of September 2026, we are 3698 members strong and growing. Please explore our pages and if you would like to join in the fun, please click the membership button at the left.

DX shipping will be quoted on an individual basis.
Please contact us for an estimated shipping cost.
