More interesting stuff from the Internet – 8/5/12

Here are some interesting items I’ve gleaned from Google+ and the amateur radio mailing lists that I’m subscribed to:

simple emf probeSimple EMF probe. EMF probes for professional use can be very pricey, but if you just want to get an idea of what’s happening with the electromagnetic fields in your vicinity, you could build this simple probe (see right) and connect it up to your oscilloscope.

Simple tilt-over tower. KD0ZZ has built a very simple tilt-over tower. Not only that, he’s also published the plans for it. If you have any questions, you can join the HamRadioHelpGroup Yahoo Group and ask your questions there.
