Winter Field Day should bring two worlds together
Deliberately stepping away from a comfortable home operating position to practice ham radio in poor conditions is not an idea too many amateurs find appealing, yet it is a situation that radio amateurs should be familiar with before it actually happens.

5 Reasons to get an Amateur Radio (Ham) License
Amateur (Ham) radio is a service and a hobby. People use it every day as a means of communication around town and around the world.

My TenTec Eagle sounds better than my Elecraft KX3
The KX3 is more fatiguing to listen to than the Eagle because it presents more noise in the audio.

80m doublet antenna
Technically, what I have is almost an 80m Doublet – there’s about 18m of wire on each “leg” and I’ve about 20ft of 300-ohm slotted feeder which comes into the Shack and through an FT240-31 choke and then about 30cm of coax to the back of the MFJ-847 tuner.

There is a good prospect of using machine learning image recognition for guessing digital modes. Ideally this would be built in to clients but it might make a good app (using the phone camera to capture the unidentified signal) or a web site where you upload a screen shot.

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.

EME In The ’80s
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.

Keeping an NVIS antenna legal on 60 meters
To compute ERP, antenna gain must be relative to a half-wave dipole antenna. An NVIS antenna has a lot more gain than a dipole.

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….
