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.

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.
