Building Solar-Powered Amateur Radio Beacons for 630 and 10-Meters
By Geir Laastad LA6LU

In the August 2015 issue of TSM, Geir wrote about “Advanced Radio Noise Filtering Using DSP Technologies.” This time Geir puts his electronics know-how to work while he shows us how he built two amateur radio beacons for opposite ends of the amateur HF spectrum: the 630 and 10-meter bands. The site for his beacons is his remote cabin in the woods—far away from everything, which is why his beacons are also powered off the grid. Using QRP Labs Ultimate3 QRSS/WSPR kits, these beacons have to be very rugged to take the abuse Norway’s winters can dish out.

TSM Reviews: AOR DV-1 Wideband Receiver
By Chris Parris

AOR is a brand well known to monitoring enthusiasts. They have a long history of making high-end receivers featuring advanced technology capable of wideband reception from longwave to the high side of UHF. “Federal Wavelengths” columnist, Chris Parris, puts this pedigreed receiver through its paces and finds some welcome pluses and a few disappointing minuses. He especially liked this radio’s ability to seek out weaker digital signals that other radios missed and he found ways to overcome the radio’s anemic audio.

Retro Radio: Finding, Storing and Savoring Vintage Amateur Radio Gear
By Richard Fisher KI6SN

Knowledgeable radio amateurs describe “vintage” transmitters, receivers and transceivers as being somewhat relative—only you know it when you see it. That’s because each of us have our own radio experiences, some dating to decades ago and others more recent. Nostalgia is a many splendored thing. Last month he looked at broadcast-band and shortwave receivers of a rich, bygone era. In this second part, his focus is on collecting, restoring and enjoying commercially manufactured vintage amateur radio equipment. As Richard shows us, restoring these ham band workhorses requires more than just a fondness for days gone buy.

VHF and Above: Sporadic-E Propagation
By Joe Lynch N6CL

From late November to early January, and again in the middle of May through the end of July, sporadic-E propagation appears more often on VHF and above frequencies in the Northern Hemisphere. This type of propagation occurs when there is a sporadic ionization of the E-layer that appears in the late morning and late afternoon local time during those months. But, working meteor-scatter Sporadic-E is not for slow hands, Joe shows you how to work fast to successfully log QSOs using this ephemeral mode. And, for once, it’s not about expensive esoteric antennas!

ATSC Off-Air Local Television: The Programming
By Mike Kohl                                                     

The Golden Age of Television is really here. Never before has there been such an abundance of choices in TV entertainment for the home. Last month, Mike hinted at multiple delivery methods being used to deliver signals. This month he looks at the content provided by local television broadcasters to their local Over-the-Air (OTA) viewers in representative regions of North America. Mike continues to show us all how to “cut the cord,” this month looking at OTA programming rewards. You might be surprised at just how many OTA channels you can find where you live.
