TSM Reviews: Yaesu FTM-100 DR: Amateur Friendly Digital Operating
By Mark Haverstock K8MSH
In 2013, Yaesu developed System Fusion, a format that retains backwards compatibility for analog along with FDMA-based digital communications. With the FTM-100DR, Yaesu has managed to create an affordable radio that integrates both analog FM and their C4FM digital modes into one package that accommodates digital users, while still keeping the analog FM crowd connected.
Early Radio Broadcasting: Publicity Stunts and Unusual Broadcasts
By John Schneider W9FGH
In the early years of radio, broadcasters were eager to explore the frontiers of the medium and found themselves in a continual series of “radio firsts,” similar to modern attempts to make it into the Guinness Book of World Records. To attract listeners, early stations sought new ways to make “radio history” by transmitting something that had never been heard before—weddings, broadcasts at sea, in the air, even under the water. In many cases such broadcasts served no purpose but to entertain and fascinate.
Using Weak Signals Software to Reach for the Sky
By Robert Gulley AK3Q
Many have no doubt heard of renowned physicist Joe Taylor K1JT, or at least JT65 or JT9 software. But weak signal mode software has progressed leaps and bounds since the introduction of these modes only a few short years ago, thanks in part to some great contributions from people around the world. The WSJT-X suite of software represents the outgrowth of these modes, and its latest incarnation, v. 1.70, has added even greater capabilities.
FCC Rewrites some Rules for CB/FRS/GMRS/MURS and Amateur Radio
By Ken Reitz KS4ZR
The FCC has recently released its Report and Order (R&O) regarding amendments to Parts 2, 15, 80, 90, 97 and 101 of the Commissions rules concerning, in part, CB, FRS/GMRS and amateur radio. We take a look at how these rules might affect your operating (spoiler alert: there’s still no sound effects or music allowed on CB!).
TV Band Re-packing Report: New Channel Assignments by TV Market
By Mike Kohl
Information has continued to be released by the FCC on the repacking of TV channel frequencies across the US. This has given Mike the opportunity to create some listings by TV market on what the local spectrum should look like at the end of the process. In this installment, TV markets are listed starting with the largest number of viewers in each market. New York, Los Angeles and Chicago top the listings, and this month we cover from Market #1 to #57 (Richmond, Virginia).

TSM Reviews: QRP Labs Ultimate 3S Transmitter Kit
By Mark Haverstock K8MSH
It’s the old radio conundrum: Is the band dead or is it that no one is listening? This month Mark looks at a beacon transmitter kit that lets you see just how active the band really is. The QRP Labs Ultimate 3S transmitter uses Weak Signal Propagation Reporter (WSPR) Frequency Shift-Keying (FSK) transmissions in beacon mode that can be received by receivers around the world set up to send back reports on a central reporting site on the Web. Mark puts this kit through its paces.
Tuning Out? History and Legacy of Longwave Broadcasting in Europe
By Georg Wiessala
Longwave broadcasting seems to be a relic from radio’s infancy. While its future is uncertain, during an era of Internet streaming and satellite beaming, it continues to hang on. Georg examines the history of longwave and explains why countries “disinvesting in AM broadcast radio make a shortsighted decision—losing an important channel for media diplomacy and international communications abroad.”
TSM Reviews: DX Engineering HF Portable TW Antennas
By Joe Lynch N6CL
TSM VHF and Above columnist, Joe Lynch N6CL, lives in a very restrictive neighborhood but, as an active ham on HF, that’s not deterred him from enjoying the radio hobby to its fullest. Joe wanted to see how well DX Engineering’s DXE-TW-2010-P 20 through 10 meters portable antenna would work—given his QTH. Find out why he says these antennas are, “worth the cost, considering the practicality they provide.”
DRM—Digital Radio Mondiale Spectrum within a Spectrum
By John Piliounis SV1OCS
Digital Radio Mondiale (DRM) has been around since 1998 and has slowly found acceptance on HF as well as the FM band. But, the lack of affordable, capable receivers has hampered its success. John Piliounis takes a look at the technical side of this open-sourced, international digital radio format that can coexist with analog signals broadcast from the same tower.
Results of FCC Incentive Auction and Repacking of US TV Spectrum
By Mike Kohl
The results are in from the FCC’s massive TV band incentive auction and now the 39-month process begins in which some stations will go off the air; others will go off the air but join another station in the market to show up on a sub-channel, while others will move from UHF to VHF TV band. Mike explains it all.
