US Navy-Marine Corps MARS Program to End
Blog Editor: This has been a long time coming. I have discussed this on this blog and other venues several times over the years. DoD should now do the smart things and combine AF and AR MARS into one service auxiliary. Failure to do so is fraud, waste and abuse of valuable HF frequency resources and the taxpayers money. As a former members it pains me to see this organization fold. Fair winds and following seas to all who served in NMCM.
From the ARRL website:
The US Department of Defense is phasing out the US Navy-Marine Corps Military Auxiliary Radio System (MARS) program. Its operational mission will transition to the other MARS service branches by the end of September.
The head of the US Navy-Marine Corps MARS program in Williamsburg, Virginia, made the announcement. The Navy-Marine Corps MARS program also supports the US Coast Guard as well as the Federal Emergency Management Agency, the US Department of Homeland Security, and local emergency management agencies.
A US Department of Defense-sponsored program, MARS branches are separately managed by their respective military service branches. MARS volunteers are Amateur Radio operators who provide auxiliary or emergency communications to local, national, and international emergency and safety organizations, as an adjunct to normal communications.

New Summer 2015 International Shortwave Broadcast Guide Now Available at Amazon
Teak Publishing is proud to announce the publication of their 9th e-book on Amazon.com -- Summer 2015 International Shortwave Broadcast Guide
So why should you listen to shortwave radio? Quite simply shortwave radio is your window to the world.
Excellent Shortwave Introduction and Program Guide by Don K3PRN
Excellent, very reasonable guide to shortwave radio. As a long time shortwave listener, the listing of all shortwave stations by UTC time is very useful to me. I had previously a shortwave website that listed only English broadcasts rather than an all station listing with the language that will be broadcast. I would highly recommend this e book for all new shortwave listeners and those that interested in a very portable listing of all stations by UTC. I only hope that this will be updated twice a year for many more years.
Five Stars by Kindle Customer
Came on time. packaged right, looks as shown and works as advertised.
So why should you listen to shortwave radio? Quite simply shortwave radio is your window to the world.
The best source of global information continues to
be shortwave radio. Throughout the world, shortwave remains the most readily
available and affordable means of communication and information. It lets you
listen to voices from around the world. You'll also learn about the lives and
concerns of people from all walks of life, from soldiers, to farmers, to
retired scholars. Shortwave radio provides nearly instantaneous coverage of
news and events from around the world.
Shortwave listening, or SWLing, is the hobby of
listening to shortwave radio broadcasts located on frequencies between 1700 kHz
and 30 MHz, also known as HF or the High Frequencies bands.
If you live in the U.S., you can easily listen to
shortwave broadcast stations from countries like North/South Korea, Iran, Australia,
Cuba, China, New Zealand, Pakistan, India, Japan, England, Egypt, Tunisia,
Oman, Saudi Arabia, Kuwait, United States and many other counties if you have a
shortwave receiver, and you know when and where to listen!
That when and where to listen is covered
comprehensively in the pages of a new edition of the International Shortwave Broadcast
Guide.
The International Shortwave Broadcast Guide (Summer
2015 edition), by Amazon bestselling author Gayle Van Horn, W4GVH, is
that all important information resource you need to tap into the worldwide
shortwave broadcast radio spectrum. It is a 24-hour station/frequency guide to “all”
the known stations currently broadcasting on shortwave radio at time of
publication. This unique shortwave resource is the “only” publication in the
world that offers a by-hour schedule that includes all language services,
frequencies and world target areas for each broadcast station. There are new
chapters that cover basic shortwave radio listening and Who’s Who in the
Shortwave Radio Spectrum. Also extensive work has been done to improve the
readability of this edition on the various Kindle platforms.
The International
Shortwave Broadcast Guide (Summer 2015 edition) is now available for
purchase worldwide from Amazon.com at http://www.amazon.com/dp/B00X8BIF0K. The price for this latest edition is still US$4.99. Since this book is
being released internationally, Amazon customers in the United Kingdom,
Germany, France Spain, Italy, Japan, India, Canada, Brazil, Mexico and
Australia can order this electronic book (e-Book) from Amazon websites directly
servicing these countries. All other countries can use the regular Amazon.com
website.
This new e-publication edition is an expanded
version of the English shortwave broadcast guide formerly printed in the pages
of Monitoring Times magazine for over 20 years. This one of a
kind e-book is now being published twice a year to correspond with station
seasonal time and frequency changes.
If you enjoy listening or monitoring HF shortwave
stations, and you miss the monthly English frequency listings formerly published
in the late Monitoring Times magazine, and multilingual station
listing in the old MTXpress electronic magazine, this valuable
tool will now be your new guide to listening to the world.
Frequency updates
between editions will be posted on her Shortwave
Central blog at: http://mt-shortwave.blogspot.com/.
And, the good news is
that you do not need to own a Kindle reader to read Amazon e-book publications.
You can read any Kindle book with Amazon’s free reading apps.
There are free Kindle
reading apps for the Kindle Cloud Reader, Smartphones (iPhone, iTouch, Android,
Windows Phone and Blackberry); computer platforms (Windows XP, Vista, 7 and 8
and Mac); Tablets (iPad, Android and Windows 8), and, of course, all of the
Kindle family of readers including the Kindle Fire series. A Kindle e-book
allows you to buy your book once and read it anywhere. You can find additional
details on these apps by checking out this link to the Amazon website at www.amazon.com/gp/feature.html?ie=UTF8&docId=1000493771.

The International Shortwave Broadcast Guide
will have wide appeal to shortwave radio hobbyists, amateur radio operators,
educators, foreign language students, news agencies, news buffs and many more interested
in listening to a global view of news and events as they happen.
If you are an amateur radio operator or shortwave
radio enthusiasts, and want to hear what is happening outside the ham bands on
that transceiver or portable shortwave radio in your shack, then this new
e-book from Teak Publishing is a must in your radio reference library.
Here are a few of the
public comments from radio hobbyists who purchased the first three editions of
this Amazon e-book.
Excellent Shortwave Introduction and Program Guide by Don K3PRN
Excellent, very reasonable guide to shortwave radio. As a long time shortwave listener, the listing of all shortwave stations by UTC time is very useful to me. I had previously a shortwave website that listed only English broadcasts rather than an all station listing with the language that will be broadcast. I would highly recommend this e book for all new shortwave listeners and those that interested in a very portable listing of all stations by UTC. I only hope that this will be updated twice a year for many more years.
Good Product by Radio Freq
Since
Monitoring Times stopped publishing shortwave radio schedules, there has been a
dearth of resources for radio-heads. This guide nicely fulfills gap. It is very
comprehensive.
It is nice someone is dedicated to SWL by Robert K.
Mallory
Very concise and well
organized. Not much to choose from these days, it is nice someone is dedicated
to SWL.
Shortwave Broadcast
Guide by
Kindle Customer
Since Monitoring
Times is no longer in publication, this guide is required for the dedicated
shortwave listener. There is information provided that I have found nowhere
else. It will be a welcome addition to any listener's equipment. Gayle Van Horn
has been publishing this research for many years and the followers are
numerous, from beginners to professionals. The author's work is accurate,
concise and thorough. If you have a shortwave radio, you need this publication
as much as a set of earphones. There is none better.
Very Good Source for
Shortwave Stations Broadcast Schedules by Kenneth Windyka
I've got to admit up front that I don't have a
strong interest in this part of the hobby. HOWEVER, Gayle Van Horn makes it
easy to determine what one can hear on the short wave bands during a particular
time period (in GMT time sorted format). I also like the internet reference
available, so that one can listen to programs via the internet even if its' not
possible via the shortwave radio.
NJ Shortwave listener
hears International Frequencies with new guide help by Stanley E Rozewski,
Jr.
This e-book is complete and accurate in presenting
a low cost SW frequency guide and important must read topics for the new or
experienced user. I liked the easy reading format, and understandable frequency
guide. I will order the second edition next year.
This is my go-to-first
reference
by Mary C Larson
When I turn on the shortwave receiver and want to
find out what's on and where to look, Van Horn's handy frequency guide is a
smart place to begin. The format is not unlike the one Monitoring Times
(R.I.P.) used each month. Presumably, updated ISBGs will be published twice per
year, but you can check for the updates on her blog, (mt-shortwave.blogspot.com).
Good value by DrP
This is an excellent well-written book that is very
affordable when compared to encyclopedic guides, e.g., the WRTH. Much the same
information is included. The first part is a nice introduction to SW listening
pitched to the beginner. Included is an informative section on purchasing a
radio spanning low-end <$100 models up through the most advanced
transceivers. The bulk of the book contains a list of world-wide SW
broadcasters, organized by frequency band. This makes it ideal for browsing one
band at a time, but much less so if you want to search for broadcasts from a
particular country.
I like this one by Charles
I have only had a brief chance to scan through this
book. From what I have seen of it I will enjoy getting in to it.
Shortwave Is Not Quite Dead by James Tedford
(Bothell, WA United States)
It was barely breathing as of late, but there is
still a lot you can hear on shortwave radio. You need more than a little
dedication, and a better-than-adequate radio to hear what remains on the HF
bands, but if you have those, you will be rewarded with a lot of interesting
audio programming. This book is a good guide to what is currently available
over the international airwaves.
