The Spectrum Monitor — September, 2017

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?

Remote Operations – ETH083

Remote Operations - ETH083

In this episode we talk with Ria Jairam, N2RJ, again. I had Ria on my podcast back in episode 76 where we talked about Software Defined Radios. This time around, we talk about Remote Operations.

Remote operations has come a long way in the past 20 years or so. I have heard about people having a remote site 10-15 years ago, but their setups is a lot harder to make. Now, you can do it with just a Radio and an internet connection. Well you might need some wires and stuff too but…

Remote Operations using a FlexRadio System

Ria was kind enough to let me use her station last week remotely. Ria lives in New Jersy and I live in Texas. While I was using it I made my first HF contact in probably 15 years to a gentleman in TN and another one from IL. So basically I was talking from Texas to New Jersey to Tennessee and Illinois.

 

Technology has advanced so far and makes working remotely a lot easier. I recently listened to an episode of the Hamradio 360: Workbench podcast where George was talking with Michael VA3MW about his setup. The reason that he did remote operations was because he lived in the city and his noise floor was way up, but he had another piece of property, a family cabin if I’m not mistaken, that he setup his station at and was able to connect remotely to it from his home.

The reasons for operating a station remotely are vast.

  • You live in an HOA or another antenna restricted location.
  • You live in a retirement home but you still want to make those DX contacts.
  • You live somewhere that has a high noise floor and you couldn’t make a contact even if you had an awesome setup
  • Maybe you can’t afford a $1000+ HF setup, you can RENT the use of a remote station.

Neighbors, street lighting, shopping malls plus much more. I have had a few QSOs on SSB when the propagation have been good and other stations have been strong so they have overthrown my QRM.

WAE from the Railroad Station (QRP)

Judy and I rode our bicycles from Andover to the Potter Place railroad station. I operated in the Worked All Europe contest and managed 9 countries in 20 minutes. The weather was perfect and 20 meters was in good shape.

What a day for a bike ride… a perfect August afternoon. It was nearly 80F with a nice breeze. We arrived at Potter Place around 3:00 pm. I tossed a half wave wire over a maple tree on the hill over looking the old station. There was a picnic table directly underneath. I used the KX3 on 20 meters.

The band was full of stations operating in the WAE contest. I had no trouble making contacts. I’ve changed my log to show the countries worked.

13 Aug-17 1945 14.043 9A1AA CW 599 599 Croatia

After nearly a dozen QSOs, I packed up for the return ride. The results from operating QRP out of a backpack with a short wire must be the closest thing to pure magic. Combined with a glorious bike ride… well… it’s fantastic!

Ham Cram Offering Free Extra Course Online

Ham Cram is accepting registrations for an online guided-study Extra Class licensing course. The course begins in late September and is co-sponsored by the Gloucester County Amateur Radio Club, GCARC.

The W1UL ham cram method has four distinguishing characteristics:

  • Incorrect answers are not studied
  • Only those questions most likely to be on the VE test are studied
  • It’s the fastest and most reliable path to a license or upgrade
  • It’s free!

This course differs substantially from the normal Ham-Cram.com independent study license prep because the Extra class pool is 50% larger than the Technician or General Class pools, making associations between question and answers more difficult. In addition the Extra subject material is more challenging.

A required book is offered for free but donations are requested. The donations will be exclusively used to enhance the ham-cram.com website. The purpose of the book is showing pool questions and answers in context.

Here is the normal (non-context) display:

(E0A05) What is one of the potential hazards of using microwaves in the amateur radio bands?

The high gain antennas commonly used can result in high exposure levels

The answer follows the question.

Here is the same question in context:

(E0A05) What is one of the potential hazards of using microwaves in the amateur radio bands?

An antenna creates by taking energy that would normally radiate from the side or back of the antenna and concentrating it in the desired direction. Microwave frequencies have exceptionally short wavelength allowing development of antennas having substantially higher amounts of radiation (gain) raising the effective radiated power in the desired direction.

Contextual usage does not make you an expert but it gives you additional insight into the question and answer pair.
Candidates complete and report on their results of assignments and participate in discussions on a dedicated email reflector. The pace of the course is initially targeted at one subelement (out of 10) per week but actual progress depends upon the pace of candidate assignment completion.

For those with commuting distance of the GCARC clubhouse in Mullica Hill, NJ (across the river from Philadelphia), the course will terminate with a two hour review session immediately followed by a VE test. However, W1UL will conduct a review session and VE test for any club in the ARRL SNJ section or any location within 70 miles of Tuckerton, NJ provided there are at least three candidates, (not all necessarily from the same club), a club furnished location for the review/VE session and the club provides two additional Extra class VEs. For people not in the Southern NJ area the email reflector used for the rest of the course will host the review.

Reserve a virtual seat for the course now since reservations may be limited.

Email urb at ham-cram dot com with reservations request and questions.
