Make a Donation
We are humbled by how many of you ask for a way to donate and support our mission to provide high-quality resources for the amateur radio community. We appreciate your support and couldn’t do it without you!
SignalStuff exists so we can work on our real passion projects: HamStudy.org, ExamTools, and our new HamBook, a complete license manual that is 100% free online. All SignalStuff sales go to paying for development, hosting, and other necessary expenses that keep the lights on.
Thank you for your support!
We created HamStudy to help aspiring hams and those wanting to progress in
the hobby get ready for their license exams.
Whether you're a complete beginner or an experienced ham, this free series of comprehensive
study guides is designed to help you earn your amateur radio license or upgrade to the next
level.
ExamTools gives VE teams the software they need to
administer exams with integrity and efficiency,
both in-person and remotely, computerized or on paper.
We sell Amateur Radio antenna products such as our popular Super-Elastic Signal
Stick™ to fund software development and keep our software tools available for everyone.
