We promote Amateur (Ham) Radio to the public in Richardson TX and the surrounding North Texas area as a useful, life-long hobby. We also serve the Richardson TX community by providing self-supporting special event, severe weather and emergency communication capabilities and networks.
Our club is comprised of over 350 amateur radio operators in Richardson, North Dallas, the surrounding communities, around Texas and even out of state, with a wide range of radio and technology interests and skills. We provide our members with many opportunities to maximize knowledge and enjoyment of amateur radio through fun, fellowship and unique learning experiences. Our members include hams ranging from teenagers to radio pioneers in their 80s! The Richardson Wireless Klub has been an ARRL affiliated club since 1952 and is a 501(c)(3) non-profit organization.
Latest RWK General Meeting Announcement & Recording
- General Meeting – May 2023
Our program this month is Antenna Analyzers – What’s Really Going On by RWK Member Kevin Grantham N5KRG. Smart Hams use antenna analyzers every day to save work while building and tuning antennas – but few know what’s going on inside the analyzer box? Kevin will attempt to get us “in the know” on these useful devices. We will also have a sampling of various antenna analyzers to look at before the meeting – If you have a favorite analyzer, bring it and show it off.

Our program this month is Making Ferrite Toroid Baluns for Dummies by John Portune W6NBC. Few hams know how to select a toroid and know how many turns on it to make a 1:1, 4:1 or 9:1 balun. The radio books are only confusing. John will present the 3 simple steps using very little math and a free on-line calculator. There is no mystery here.
