TSM Review: Yaesu FTDX 101D

By Mark Haverstock K8MSH

During the last decade, on average, Yaesu has marketed a new HF transceiver almost every year. Finally, they got on the SDR bandwagon with their latest model, the FTDX 101D, which pays homage to founder Sako Hasegawa JA1MP. It also commemorates the classic FT-101 series, a very successful and popular Yaesu transceiver sold from 1970 to 1985. This new model offers features and performance hams of that era only dreamed of. Mark walks us through the details of this feature-packed model that boasts some very impressive numbers.


TSM Reviews: MFJ-1026 Deluxe Noise-Canceling Signal Enhancer

By Bob Grove W8JHD

Electrical and electronic devices saturate civilized society. It’s no wonder that the side effects of their electromagnetic radiation compete with radio communication. There are several approaches to avoid this interference.

Bob explains how it works and how well it works.


Othernet Free Satellite Radio/Text Service Update

By Kenneth Barbi

Over the past three years we have kept up with an ambitious project designed to provide free access to information for those millions not served by traditional Internet Service Providers. Using an inexpensive hardware platform called Dreamcatcher, data can be downlinked via two Ku-band satellites—one covering North America and one covering much of Europe and the UK. While it’s not a two-way Internet experience, it’s a project that has possibilities and provides real-world hands-on activities for electronic tinkerers.

Crystal Clear: How a 1922 Circular Brought the Wonderment of Radio to the Farm

By Richard Fisher KI6SN

In 1922 the federal government wanted the millions of rural farm families to have access to the first wave of electronic information available in the 20th Century—otherwise known as radio. To do so they knew farmers would have to build their own receivers and learn how to use them, so the US Department of Commerce published a booklet known as Circular No. 120 explaining exactly how it was to be done. Following those instructions, Richard built this state-of-the art 1922 crystal set and made it work. You can too.
