Antennas : Moxon- Reversible 40 Meter Moxon
new
- The author wants a compact, switchable antenna for 40-meter ham radio. They compare 3 designs: rectangle, short-tipped W6NL, and T-hat. All work well electrically, but mechanics matter for a large antenna. The rectangle needs strong support, while the T-hat is sturdier with slightly longer elements. The T-hat design wins for now, but the author will focus on its mechanical details next.

- Reducing RFI from PoE Devices
new
- Hams can be annoyed by noise from PoE cameras and access points. These devices and their long cables act like antennas, picking up and spreading unwanted radio signals. By wrapping ferrites around the cable will reduce this noise. It won't silence it completely, but it can make a big difference.
