Stories you’ll find in our September, 2017 issue:
Icom IC-R8600 All-Band All-Mode Software Defined Receiver
By Bob Grove W8JHD
To say that Bob Grove, a longtime radio reviewer, is impressed with this new offering from Icom, is a severe understatement. Bob writes, “With the release of this Software Defined Receiver, analog receiver design is relegated to history. Never before have so many features and options been offered in one general-coverage receiver. No wonder it comes with a 93-page, 8 x 10-inch instruction manual!”
Electrical Pioneers: The Life and Times of Guglielmo Marconi and Ernst Alexanderson
By Georg Wiessala
Regular TSM contributor, Georg Wiessala, explores the lives of two of radio’s legendary pioneers. He notes, “It is hard to imagine in our own age just how groundbreaking, confusing and inspirational the work of the early radio pioneers was in theirs, at a time when even the Eiffel Tower became a radio mast. However, our era of borderless communication and technological advance carries with it echoes of the ‘globalization’ of earlier times, as the 19th Century turned into the 20th.”
Rocky Mountain Ham Radio Inc., the Dayton Hamvention 2016 Club of the Year
By Wayne Heinen N0POH
RM Ham, as Rocky Mountain Ham Radio, Inc., is known, is a different kind of amateur radio group—it’s not a club where you fill out an application, pay your dues and join. You can only become a member by participating with the group and over time, if you pitch in on a regular basis, you get an invitation to have your name added to the roster. The exclusive nature of this club is actually its greatest strength. Wayne explains the incredible things this group of hams have accomplished and how your club can benefit from their organizational skills.
Impact of the FCC’s TV-Band Repack
By Mike Kohl
Despite the reported $1.75 billion set aside by Congress to pay winners in the spectrum auction, there are many surprises awaiting the FCC that perhaps should have been expected in advance. Not the least of which forces the FCC to go back to congress to ask for enough money to affect band repack changes. Radio stations, low-power TV translators, even amateur radio clubs will be affected by changes mandated by the FCC. Mike explains the process currently changing the landscape of America’s TV band that will continue taking place over the next three years.

Just how do they do it?
The Banggood portable BF-UV8D retails on eBay for just £14.25 with free shipping to the UK from China. In all honesty, just how can anyone compete?
This is a 5W RF 400-480MHz transceiver and comes complete with charger, back clip, antenna and battery. If I was Yaesu, Icom and Kenwood I’d throw in the towel now. Once the Chinese really wake up, the Japanese manufacturers have no chance of surviving. The Japanese will be driven more and more to niche markets, then die. I cannot see them staying around in the amateur market for too long.
At the moment the Japanese have quality on their side, but the Chinese will soon be as good. At the moment it seems everything, just about, is made in China. Recently I bought some Olympus binoculars – these said “Made in China”. The Chinese seem to be able to make most things at prices that simply cannot be matched.
20 years from now we’ll be living in a very different world.
You can buy a 433MHz module for just over £1 with free shipping from China!!
They make profits too, so how do they do it?
