Welcome to AA6E.net

This site is dedicated to Amateur ("ham) Radio and related topics at AA6E, Branford, Connecticut, USA. (So what is Amateur Radio?)

AA6E can currently operate in the 80, 40, 30, 20, 17, 15, 12, 10, 6, and 2 Meter and 70 centimeter Amateur bands (3.5 to 450 MHz), at power levels from 5 to 1500 Watts. Operating modes include CW (Morse Code), digital keyboard modes (JT65, PSK31 and others), SSB voice, narrowband FM, and more.

In ham radio, we often identify by our callsign. AA6E is the alter ego of Martin Ewing. You can see some biographical data here.

Radio Astronomy and Amateur Radio

We have recently started up a discussion group for folks who have a professional background in astronomy, particularly radio astronomy, and also in Amateur Radio. If you happen to fall into this happy group, please sign yourself up and join us at

Other Topics

  • Tiny Computers. Using small boards to run large (typically Linux-based) software applications is an interesting and relatively inexpensive pursuit. We are using the Beagleboard, Raspberry Pi, and similar boards. Arduinos and PICs are fine for smaller applications, but the Linux-capable boards offer ARM processors with mass storage and a rich selection of peripherals.
  • Saga of the ISPs. We have struggled with a number of Internet Service Providers and tried to resolved some engineering problems, particularly with the AT&T U-verse service we installed in Sept., 2010. We asked is it compatible with Amateur Radio? Does it even work reliably without ham interference? Well, the quick answer is no, it's not compatible with HF operation below 10 MHz at 100 W or more, at least not without major effort. So now the story is about Comcast, DOCSIS 3.x, etc.
  • GPS in the Shack, Adventures in time-keeping, time-tagging, and watching for continental drift.
