Urban HF Noise
Over the past 30 years, HF radio noise in urban areas has steadily increased. S6-S9 noise levels are common, which makes it hard to listen to the signals we want to receive.

Radio controlled pacemakers are easily hacked
Doctors use RF signals to adjust pacemakers so that instead of slicing a patient open, they can change the pacemakers parameters which in turn avoids unnecessary surgery.

Adding ethernet lightning protection to the shack
The whole idea with isolation is to reduce the vulnerability of the on-board Flex-6700’s Ethernet adapter to stray static or electrical charge energizing a CAT6e cable.

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).
