About Me

Ron Schwartz
Licensed since 1972. My main interests are CW DX & contests, on HF and VHF. Having fun is more important to me than winning. I build and design towers and antennas, create hardware and software devices to run my large station. I often play with QRP. I am a firm believer in lifelong learning. My hope is that others will enjoy the blog as much as I enjoy writing it.
