The Spectrum Monitor — January, 2017

Stories you’ll find in our January, 2017 issue:

Living the Shortwave Broadcasting Dream at WTWW
By Keith Baker KB1SF/VA3KSF

Ted Randall WB8PUM is a lucky guy. Every day he gets to play radio with some pretty big transmitters and some very large antennas. What’s more, his whole family gets to play too. And at night, after work, he gets to play some more! Keith Baker tells us all about the radio engineer behind the mic at the “QSO Radio Show,” Tuesday evenings on 5.085 MHz shortwave.

SteppIR BigIR MK IV: Going to Great Lengths
By Mark Haverstock K8MSH

In limited spaces, the vertical has become the go-to antenna for many installations. They seem like a perfect solution; footprints are small, and simple radial systems are easy to hide in the turf. Verticals also exhibit lower angles of radiation, making them perfect for DX work. The SteppIR BigIR stands out as an alternative, providing a system that will mechanically create a quarter wave vertical on any of the major ham bands–even MARS frequencies.

Going Mobile with SDR
By Robert Gulley AK3Q

There are a number of reasons to go mobile with an SDR, not the least of which is the adventure factor! Every new place offers new listening opportunities; it is a bit like fingerprints in that no two locations are exactly the same. Every location offers something different, and with the wide-ranging capabilities of the SDR there are always new things to hear. Robert shows us what to bring along, how to hook up to power and an antenna. It’s easier than you might think!

The Extra Punch of SSB on CB
By Cory Sickles

In recent months, Cory has spent a good deal of time on the VHF and UHF aspects of Citizens Band, but CB is thought of more for what goes on at 27 MHz. To be sure, the core HF allocation is where the majority of CB users start and where they stay. As a simple option to enter the two-way radio hobby, it’s hard to beat. But that doesn’t mean the world of CB has to be limited to 4 watts of amplitude modulation. Cory explains what happens when CB goes SSB.

Basics of Motorized Satellite Reception: Part 1
By Mike Kohl

Free-to-Air satellite-TV enthusiasts get the most out of their systems, whether they’re Ku-only or C/Ku-Band big-dish systems, when they are motorized. But, moving small dishes or big dishes requires the right sort of motor and proper connections. Mike shows us how it’s done in Part 1.

Klingenfuss Utility Monitoring Book
By Bob Grove W8JHD

For several decades, Joerg Klingenfuss has been the consummate publisher of radio frequency directories on a global basis. His latest offerings include frequency guides, databases and CDs, code books, signal sound CDs, a frequency list for the Perseus SDR, screen-shots on a USB stick, and Internet web pages. Bob Grove takes a look at this extensive new collection.

Unlike today’s widespread JT65B usage on eme, where signals can be many db into the noise and inaudible by ear, eme contacts could only be completed by actually copying signals that you could hear with your ears. This usually required big antennas and lots of power.

FX-9A Revisted

Got the radio back after repairs and after a short test I am happy to say that it is receiving 100 times better then it was when I first got the unit. Thanks to Frankie at Windcamp for all of his help, he is a super person to deal with.
http://www.windcamp-gear.com

I was told by Frankie when it was shipped away and on the bench that there was a bad solder connection and a virtual switch issue, what-ever that might be in English.

I am happy to say that the radio came back new and working well on all bands. Receive is like many of the other videos I have watched on the internet.
I will have more updates and videos of the unit in action after the holidays.

Merry Christmas and A Happy New Year one and all….

The Spectrum Monitor — December, 2016

Stories you’ll find in our December, 2016 issue:

The Coast Guard Cutter Courier: “A Cold War-era Battleship without Guns”
By John Schneider W9FGH

The Voice of America operated a unique shipboard radio broadcasting facility on the medium wave and shortwave bands in the Mediterranean Sea from 1952 to 1964. The US Coast Guard Cutter Courier was a seagoing Cold War shipboard broadcaster, which preceded the famous pirate radio ships of the 1960s and 70s and was the home to the most powerful transmitter ever operated aboard a ship. But, it was not always smooth sailing. There were complications with the 900-foot balloon-tethered medium wave antenna and constant jamming from Russian-based transmitters.

Experiences of a (Relatively) Young Ham with Vintage Radios
By W. Eric McFadden WD8RIF

While the author has been a licensed ham for 38 years, he’s relatively young. And, since most of his operating gear is modern, he’s fairly new to vintage radio. He writes that he wanted to experience what the hobby was like for earlier generations and he felt the contagion of many of his close amateur radio friends who are quite into vacuum tube-era gear. He’s apparently a quick study because now he has some good-looking vintage gear in his shack, including a Heathkit HW-16 and a Drake 2-NT transmitter and 2-C receiver as well as tube-fired 6-meter gear. He’s definitely hooked!

Beware the Mods: Drake 2NT Transmitter
By Rich Post KB8TAD

Longtime vintage radio guru, Rich Post KB8TAD, helps Eric McFadden restore his Drake 2-NT transmitter and shows the rest of us some of the things he does to give vintage radio gear new life. Here’s a hint: It’s not easy and it helps to have good diagnostic equipment, skills to operate that equipment and many decades of understanding the variables of tube-technology.

Shortwave Listening with the “Old-Timers”
By Eric Beheim

Growing up in the 1950s and listening to his grandfather’s 1936 23-tube Scott All-Wave console shortwave radio was a pretty good start for young Eric Beheim. That’s why today, Eric likes to listen to the shortwave bands on number of vintage shortwave radios, including a 1936 Hallicrafters S-20R Sky Champion and a 1942 Zenith model 7G605 Transoceanic “Clipper” among others. Listening is not as easy as you might think. Eric writes, “Most older radios lack the sensitivity, selectivity, and stability that we take for granted in our modern sets. But that’s what makes monitoring with the ‘old timers’ both challenging and exciting.”

A Salute to the Esteemed Regenerative Receiver
By Richard Fisher KI6SN

Fifty years ago, a teenage Richard Fisher, sporting his Novice call, WN1DWL, found he was at loose ends during his high school winter break. What better way to pass the time than to build a regenerative receiver that he could use to cover the ham bands from 160 through 10 meters? It was a project financially within reach of “a broke 16 year-old.” Years later, while he still had the rig, it had fallen victim to the ravages of time and “parts scrounging.” Now, Richard thought, what better way to celebrate the 50th anniversary of that little radio than to restore it to its full regenerative glory?
