ARRL is the national association of amateur radio in the US. Founded in 1914 by Hiram Percy Maxim as The American Radio Relay League, ARRL is a noncommercial organisation of radio amateurs. ARRL’s underpinnings as Amateur Radio’s witness, partner and forum are defined by five pillars: Public Service, Advocacy, Education, Technology, and Membership.


FT-817 Filter Module

The LASERBEAM-817 Module has been designed to specifically compliment the FT-817. It has a new filter line-up, optimised gain for this application, revised switching and a filter select LED. The LASERBEAM-817 improves on the performance of the stock ceramic SSB filter and has a superior shape-factor when compared to the aftermarket Collins Mechanical Filters.



The WSPRlite is a special test transmitter that sends a signal to a worldwide network of receiving stations. When used with the web-based DXplorer system, it's a powerful way to evaluate antenna performance. Going way beyond antenna modelling or antenna analyzers, this unique system allows you to see how your antenna is performing in its actual location and in real-time. This type of analysis has never been possible before.
