It doesn’t help a whole lot if you attempt to get on the air, and nobody hears you. Even if I have the very best equipment that money can buy, including a great antenna, and even though I feel certain everybody this side of Richland county can hear me, it’s still possible that they can’t. If you’re talking on simplex, your antenna could be oriented incorrectly, you might have a loose or corroded connection, you might not be speaking close enough to the microphone, or your battery is on its last breath. If you’re trying to talk through a repeater,Read More →

Just about every modern ham radio has two operating modes: Memory (also known as Channel) mode and VFO (also known as Frequency) mode. Memory or Channel mode is merely a set of memory channels that have a number of frequencies stored in them, along with the appropriate settings for each, such as offset, tone, and power level. You select each by simply scrolling through the stored channels. VFO or Frequency mode, however, doesn’t quite work the same way, and it’s often convenient to understand how to work it. VFO stands for variable-frequency oscillator, which simply means that this mode willRead More →

The new 60-meter frequencies approved by the FCC in December will become available to amateurs as of February 13, 2026, along with new power restrictions on those frequencies. It’s a bit confusing, as different rules apply to different segments of the band. The changes result from the FCC’s action to approve a worldwide 60-meter amateur allocation made by the World Radiocommunication Conference in 2015 (WRC-15). See https://tinyurl.com/mt8p8jpa. As of February 13, FCC-licensed amateur operators holding General Class or higher licenses may operate on a secondary basis anywhere between 5351.5 and 5366.5 kHz, subject to a maximum bandwidth of 2.8 kHzRead More →

Your ham radio station is a system of equipment and antennas. To operate properly, each piece of equipment expects certain signals and settings at each of its connectors and controls. You can trace many station problems to those signals and settings, often without using any test equipment more sophisticated than a voltmeter. Most station problems fall into two categories: RF and operational. RF problems are things such as high SWR, no signals, and reports of poor signal quality. Operational problems include not turning on (or off) properly, not keying (or keying inappropriately), or no communications between pieces of equipment. RFRead More →

A group of students at Cornell University is seeking participation from radio amateurs who are equipped with satellite stations for help in listening for signals from a retroreflective laser sail that is scheduled to be deployed later this week. The sail is currently attached to a 1U CubeSat that was launched early Tuesday, December 2, 2025, from the International Space Station, but will separate and become its own free-flying spacecraft equipped with four tiny “ChipSat” flight computers that will transmit telemetry data back to Earth. This is the first flight of their ChipSats, and it is this data that theRead More →
