Ham Satellites

Since the early 1960’s, Amateur Radio’s people have had their own ham satellites and use everything from large earth-stations to small, hand-held antennas to relay satellite signals around the world.

Meteors and the Moon – WSJT

WSJT is a computer program for VHF/UHF communication using state of the art digital techniques.  It can decode fraction-of-a-second signals reflected from ionized meteor trails, as well as steady signals more than 10 dB weaker than those required for conventional CW.  One of its operating modes, JT65, is particularly optimized for amateur EME (Earth-Moon-Earth) communications.  [...]

D-Star

What is D-STAR?
D-STAR is a new ham radio standard which, when made into a system, offers both digital voice and data communication. It connects repeater sites over microwave links and the Internet and forms a wide area ham radio network. The DSTAR system provides a new capability and functionality to the ham radio world and [...]

APRS

Sure your dashboard GPS might tell you where you are. But how about seeing and tracking where other people are located in real time?
Long-time packeteer Bob Bruninga, WB4APR, developed the Automatic Packet Reporting System (APRS), which allows packet radio to track real-time events. It deviates markedly from the usual message- and text-transfer activity. Instead, APRS [...]

NBEMS

 
Having realized the shortcomings of current emergency messaging systems, including those that utilize voice, CW, or email robots, a ham operator, Skip Teller, KH6TY, saw the need for fast, reliable, emergency message transfer that would not be subject to any errors in translation from the spoken word to the written word, or from Morse Code [...]

Green Radio ? -We do that!

Larry D. Barr, K5WLF, is a long-time proponent of renewable energy use, has lived off-grid in the past and is the owner of Rebel Wolf Energy Systems, a renewable energy (RE) consulting and design company. So, it was only natural that he’d look for ways to combine his passion for RE [...]

MiMo & Mike Kassner

What’s MiMo ?
 
Multiple Input/Multiple Output - Pronounced “my-mo,”
it is the use of multiple transmitters and receivers (multiple antennas) on wireless devices for improved performance. When two transmitters and two or more receivers are used, two simultaneous data streams can be sent, which double the data rate. Multiple receivers alone allow greater distances between devices. The IEEE [...]

SDR – Download a new radio? Sure!

Download a new radio?  Yes, we do that!
 
 

Since the beginning of radio itself, signals arrived at antennas and were processed by bits of hardware so that the information they carried could be understood by human beings. A century ago, the hardware amounted to little more than crystals and coils of wire. Vacuum tubes followed, which [...]

SETI – Project ARGUS

Is anyone out there?

Project Argus is still going strong after a decade, and hams are
driving the technical developments. 135 Project Argus stations are
operating in 26 countries around the world.
What Is Project Argus?
Perhaps the most ambitious microwave SETI project ever undertaken without Government equipment or funding, Project Argus is an effort to deploy and coordinate roughly [...]
