TSM Reviews: FlexRadio 6400M All-Mode HF+6 Transceiver

By Mark Haverstock K8MSH

     While computer control has become integrated into amateur radio transceivers in recent years, there is still a substantial faction of amateur radio operators who want to hold onto the traditional buttons and knobs of their radios. FlexRadio’s new additions to the Signature Series give amateurs both options. The base Flex 6400 model is computer controlled, but they’ve also created an M version (M for Maestro) with traditional knobs, buttons and a touch display screen as well. The 6400M is an improved version of the 6300, with better specs, processors, and costs $500 less—at a price tag of $2000. It borrows features from both the 6300 and 6500 (both of which were recently discontinued). Note that the 6400 and 6400M models are identical, with the exception of the Maestro control interface. But, you’ll need to find a little extra table space at the operator’s position—it is bigger than a breadbox, with both the basic 6400 and the M versions have the same footprint and measure 7 x 14 x 13.125 inches. Mark unpacks the details of this modern and very capable HF+6 transceiver 


Giving Undersea Cable its Just Deserts – 160 Years Past Due

By Richard Fisher KI6SN

     Marconi got the hoopla for the first trans-Atlantic wireless communication. His transmission of the Morse letter S sped through the airwaves between the Canadian maritime province of Newfoundland and Cornwall, England, in the waning days of 1901. But 43 years earlier – in 1858 – it was New York businessman Cyrus Field who was the impetus behind the remarkable achievement of the first telegraphy Communications between two continents—Newfoundland to Ireland—under the sea. Why no such accolades for Cyrus in reciting the technological achievements in communication of the mid-19th and early-20th centuries, 160 years ago, no less? Richard dives deep to find an amazing web of undersea cables stretching around the entire globe—an vital part of modern communications.


TSM Reviews: Yaesu FTM-750DR VHF/UHF Transceiver

By Cory GB Sickles WA3UVV 

     Yaesu recently introduced and is now shipping another System Fusion transceiver - the FTM-7250 mobile. As this month’s installment of Digitally Speaking covers connectors and genders, perhaps the simplest way to describe the ‘7250 is for you to imagine that the FTM-3200 (VHF) and FTM-3207 (UHF) monobanders got together and had a baby. With the April release of the FTM-7250, Yaesu now offers a total of eight radios, with an even split between entry-level transceivers with “core” features and those with advanced-level feature sets. Think about that for a moment. Eight radios, plus two repeaters and two different networking concepts. That’s a fairly diverse selection of equipment – not to mention the various means of third-party support for this DV methodology – that is only four years old, from the time of its full release.


Free-to-Air Satellite-TV List Update

By Mike Kohl

     Free-to-Air (FTA) satellite-TV enthusiasts sometimes have a challenge keeping track of satellite names and positions. Throughout the years aerospace companies merge, creating new names for their fleet, or launch a new series of satellites, reflecting advances in technology. This month, Mike has created an updated list for North American FTA viewers covering eastern Atlantic arc satellites from 1.0 degrees West longitude, across our domestic satellite arc, and extending to 166 East, which can be received by those with a 3 to 4 meter C-band dish from unobstructed locations on the West Coast. In addition to updating the list of names to reflect mergers and acquisitions in the industry and new satellites replacing old, Mike gives you tips on aligning fixed and steerable dishes.
