There are many ways to test HF antennas ranging from simulation to various antenna analyzers and bridges. However, nothing can replace simply using the antenna to see how it works. …read more Continue reading Testing Antennas with WSPR
The average person’s perception of a ham radio operator, assuming they even know what that means, is more than likely some graybeard huddled over the knobs of a war-surplus transmitter …read more Continue reading Helping Secure Amateur Radio’s Digital Future
[David], DL1DN, is an Amateur Radio enthusiast with a penchant for low-power (QRP) portable operations. Recently he was out and about, and found that 10 m propagation was wide open. Not …read more Continue reading Aluminum Foil 20 cm Antenna for 10 m Operation

If there’s one thing that amateur radio operators are good at, it’s turning just about anything into an antenna. And hams have a long history of portable operations, too, where …read more Continue reading Wind-Up Tape Measure Transformed into Portable Ham Antenna
Ham radio operators can be pretty selective about their gear. Some are old-school tube purists who would never think of touching a rig containing transistors, and others are perfectly happy …read more Continue reading Homemade Panadapter Brings Waterfall to Old Radio
If you read old antenna books, you’ll probably see the idea of phased vertical antennas. These use certain lengths of coax to control the phase of a signal going to …read more Continue reading Directional Antenna 3-Way
[G3OJV] knows the pain of trying to operate a ham radio transmitter on a small lot. His recent video shows how to put up a workable basic HF antenna in …read more Continue reading Ham Antenna Fits Almost Anywhere
