This site documents my radio experiments and setup. See the navigation bar for sections and links to documentation.
I will occasionally blog interesting topics I find related to ham-radio.
Peter put together two Heltec V3 radios with 2 directional antennas, then mounted it to the top of his 50’ tower to create a Meshtastic relay station for long-range repeating.
lcamtuf put together an excellent primer on how radios work. Their goal was to “provide an introduction to radio that’s free of ham jargon and advanced math” and I think they succeeded. It’s well worth a review, even if you’re an experienced ham.
The video below is one of the excellent demos in the article:
W2AEW put together an excellent discussion of CW on his youtube channel. His video teaches how to calculate the occupied bandwidth (OBW) of a morse conversation.
Manoel shared his efforts to get M17 working on ICOM IC-F5060 mobile radios and IC-F3162 HTs.
This is a really cool effort. More hardware that can run M17 the better!
Tavis shared his work to use a low-cost solar light as a waterproof enclosure with RAK baseboards.
Hackaday shared a video from the National VOA Museum of Broadcasting about the history of the 500kW WLW AM broadcast transmitter. WLW was sometimes called “the nation’s channel” because it was so powerful you could hear it in most of the United States.
The tubes in this transmitter are amazing!
