Here are some items of note from my inbox:
- My partner in crime down at WA2HOM, Ovide, K8EV, is working with Professor Ray, who does science shows for kids down at the Ann Arbor Hands-On Museum, to develop a show about radio. In researching this, Ovide happened across the Happy Scientist’s experiment on AM and FM radio waves. There are a bunch of other interesting experiments on the site, but you have to subscribe to the site, in other words pay, to view them.
- openEMS is a free and open electromagnetic field solver using the FDTD method. Matlab or Octave are used as an easy and flexible scripting interface. I haven’t yet tried this out, but it sounds like a neat tool to play around with.
- TheRadioBoard is a forum for the homemade radio builder. There are forums for crystal radio builders, tube radio builders, and solid state radio builders, as well as a swap forum and antenna forum.
