31 builds, newest firstUsing WSPR technology for digital ham communication
For maximizing reliable digital communication range using WSPR technology today, you should prioritize higher transmitted power and careful antenna selection over simply optimizing the bandwidth; whil…
Understanding how ham radio repeaters work
A repeater does not simply boost your signal; it is a complex transceiving station that captures an incoming signal, processes it—typically adding tones or passing through preambles—and then re-transm…
Operating on the 10 meter band for amateur radio
Operating on the 10 meter band today requires understanding a complex balance between modern digital efficiency and traditional high-power DXing; while the general maximum transmitter power for US ama…
Using DMR technology in amateur radio communications
For reliable, modern networking across varying distances, a combination of DMR paired with traditional narrowband modes like SSB remains the most robust choice; however, if forced to choose only one t…
Learning about ham radio frequency bands
The biggest mistake newcomers make when starting to learn about amateur radio bands is assuming that the frequency allocated dictates the type of signal or complexity of operation, often leading them …
