TSM Reviews: Icom IC-7610
By Mark Haverstock K8MSH

At Hamvention 2017, we got our first official peek at the IC-7610. It was billed as the next big thing in amateur radio transceivers, containing a more advanced set of features than the IC-7300. And, it’s loaded: An Ethernet port to run the radio remotely; an onboard RS-BA1 server means no PC or software is required; left and right speaker outputs; USB 2.0 and 3.0 ports; built-in RTTY/PSK on-screen decoder and encoder; TX memory means you can do basic QSO or contest operations without using an external device or software. And that’s just to start! Mark puts this rig through its paces.

‘De-Frankensteining’ Electricity: Life and Work of Michael Faraday and Joseph Henry
By Georg Wiessala

There are significant parallels between the lives and careers of Michael Faraday and Joseph Henry: They lived in times when gases and electricity fascinated people and were among the first to work by scientific method, through controlled experiments and experimental science. More generally, both researchers were born in poverty and seriously troubling family backgrounds. Both were apprenticed at a young age, both became eminent scientists and outstanding science communicators, educators and lecturers. Georg examines the lives of these two giants of electricity.

Facing the Challenge of Making Ends Meet at Nonprofit Radio Stations
By Richard Fisher KI6SN

The world of Low Power FM (LPFM) radio is a far cry from the well-heeled world of their distant cousins—powerful noncommercial radio stations in big cities. Instead of feasting on highly organized quarterly fundraisers that can bring in hundreds of thousands of dollars, LPFMs can often be heard pleading for day-to-day funds to fix air conditioners, CD players, even transmitters. Richard looks into this seldom reported part of American radio.

Yaesu FTM-3207DR
By Cory GB Sickles WA3UVV

While prototypes of the FTM-3207 were shown at the Dayton Hamvention in 2017, it was not until nearly the end of the year that the radios started shipping. This happened for several reasons – not the least of which was the reveal of System Fusion II – with new features, a new repeater and upgraded firmware for existing radios. Understandably, upgrading and enhancing the “System” part of System Fusion took precedence over the release of a new radio. The upside is that when the FTM-3207 was released, it had some unexpected and welcome new features making it fully System Fusion II- ready and then some. Cory takes a look at the Yaesu FTM-3207 and speculates on the future of Digital Voice on the VHF/UHF amateur bands.

Channel Master’s New Over-the-Air TV Tuner/DVR with Interactive On-Screen Guide
By Ken Reitz KS4ZR

The landscape has been ripe for a digital OTA-TV tuner with recording capabilities and interactive guide. Channel Master has previously released similar products, which we have reviewed in years past, but in order to compete with TiVo or an Over-the-Top (OTT) device such as Roku and deliver a more cable/satellite-type viewing experience, Internet connectivity would be required. That brought the company to launch its latest effort in March—the CM-7600 Stream+ Media Player, an OTA-TV/Internet set-top box. We take a look at how this new Channel Master product works today.
