TSM Reviews: Penntek TR-35

By Thomas Witherspoon K4SWL

The new Penntek TR-35 is a four-band, CW-only, 5-Watt QRP transceiver that’s available both as a kit and as a factory assembled and tested unit. Designed by John Dillon WA3RNC, this rugged and very capable rig weighs just 10.6 ounces and sports a surprising number of features despite its minimalist appearance. Thomas notes, “It’s not complicated, and that’s the point—it’s really a joy to use!”


Howard Hughes’ 1938 Around-the-World Flight

By Scott A. Caldwell

There were fewer more dashing characters on the global scene in 1938 than Howard Hughes. At just 33 years old, he had made a name for himself as a multimillionaire aircraft designer, test pilot, movie director/producer and bon vivantamong Hollywood’s elite. Just one year after Amelia Earhart’s disastrous global flight and one year before the world was plunged into world war, Hughes set off on his own flight with plenty of help from radio amateurs along the way.

The four-day extravaganza was reported breathlessly by the nation’s radio networks, daily newspapers and the many monthly radio magazines.

By William R. Hepburn

While most North American TV stations switched to digital Over-the-Air TV broadcasting in 2009, there are still quite a number of exceptions to the digital rule. TV DX expert, William Hepburn argues that ‘we are currently in the midst of one of the greatest eras for international TV DX. Analog signals from other countries are still around, waiting to be captured by your antenna. He shows us how it’s done.


Amateur Radio and Computers: Part 2

By Cory GB Sickles WA3UVV

In the second part of this series, Cory, examines the progress of computers in the radio shack for both hams and shortwave listeners. Using 5.25-inch floppy disks from software companies long since disappeared, early adopters of computers in the shack were paving the way for developments we now take for granted. Along the way, new transmission modes changed many aspects of operating including previously unheard-of possibilities such as low-power Earth-Moon-Earth contacts.
