Welcome to AA6E.net
This site is dedicated to Amateur 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 (PSK31 and others), SSB voice, and narrowband FM.
Amateur Radio publications by Martin Ewing, AA6E:
- Tiny Python Panadapter (QST, April, 2014, pp 33-38) This project describes Python software that will produce a panadapter display from the I/Q audio IF available from some receivers. Click link for further info.
- A Software-Based Remote Receiver Solution (QEX, Jan/Feb, 2014, pp 3-6). This is a project to support a remote receiving station using an inexpensive Linux computer along with a base station PC. Click link for further info.
- ABC's of Software Defined Radio -- Why your next radio will be SDR, ARRL, 2012. A book showing how modern communications radios are put together, and how they're almost all basically SDR these days, even if they're not marketed that way. SDR and DSP technology is the economical way to build flexible radios with good performance.
- “SRL QS1R Software Defined Receiver”, Product Review, QST, September, 2010, pp 41-44.
- 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.
