Sweden (Again) Rejects DAB

Degen-DE27Digital Radio FM Europe blog is reporting Sweden wants to keep FM radio:

Parliament Confirms Rejection of DAB Radio in Sweden [updated]

Public radio continues on FM and will push for extending its remit to include digital radio online.

The Constitutional Standing Committee (KU) in Riksdagen (the Parliament) has processed the government missive regarding the 2015 National Audit review of digital radio in which the proposal for a transition from FM to DAB+ in 2017-2022 was rejected. After a short debate and without objection from any of the eight political parties Riksdagen today appended the missive to the protocol. This marks the end of 24 years of efforts to replace FM with DAB in Sweden.
Already in June 2015 the Government took the decision to reject the proposal for a digital transition for terrestrial radio. In November this was piggy-backed in the budget proposal to the Parliament.
——————–
This vote in the committee did not come as a big surprise as there has been an increasing skepticism in most parties against closing the FM band. A year ago in the consultation round the proposal was put into question or rejected by most qualified state institutions as PTS the telecom authority, KTH Royal Institute Of Technology, the Armed Forces, the Transport Agency and the Competition Authority as well as organizations as Royal Swedish Academy of Engineering Sciences, Ericsson and the Community Radio Assn.
——————–
KU has been listening to the arguments for DAB+ from the two commercial networks and the public radio Sveriges Radio (SR) as well as critical comments by the Public Service Council. KU notes that the Government in its missive says that it cannot be ruled out that the question of digitalization of terrestrial radio will be on a future agenda. KU is satisfied with the Government plan to observe international developments. However, there was no other comments by the committee other than the missive should be appended to the protocol.
——————–
This marks the end of 24 year period of futile efforts to introduce the DAB technology in Sweden. SR started testing DAB in Stockholm continuous since 1992 and officially went on air 1995 the same year as BBC introduced DAB in the UK.  2005 DAB was rejected for the first time by the social democratic government. Program have been broadcast in an inofficial mode via DAB and DAB+ transmitter in four major cities but few listeners are reported.
 ——————–
Today up to a third of all listening on the public radio channels are on-line. This is much due to the high smartphone usage on 3G/4G LTE networks in Sweden. While forced to leave the DAB agenda SR will now request that the politicians will include its Internet activities in the next public service remit 2018.
——————–
The two commercial radio networks Bauer and MTG still hold licenses to start DAB+ broadcasting later this year. But they are not expected to go DAB alone without having the public radio onboard. 60 % of the radio audience in Sweden is listening to SR. In the consultation round the DAB proposal was rejected by the community radio organisations.

1944 WWII Hallicrafters Shortwave Radio Promo

WWII-HallicraftersInteresting 15 min. video demonstrating the Army Signal Corps using an Hallicrafters SCR-299.

While certainly a promotional piece for Hallicrafters, this has great footage and captures a bit of the excitement of radio expanding into new frontiers. There is a discussion of how the radio was modified for military conditions as well as some innovations which were implemented to make such a system mobile.

As an aside, it never ceases to amaze me how clear and crisp black and white film technology of the time seems somehow better than the color images which replaced it. But that may just be me — a black-and-white guy living in a colorized world!

There is a second part to this video, as well as other WWII-era videos available on YouTube with a bit of searching, and of course don’t forget to check out the SWLing’s Shortwave Radio Archive page for more interesting shortwave audio old and new!

Brilliant Article on RTL-SDR Dongle Uses

sdr-Mario2Frequent contributor Mario Filippi N2HUN has written a brilliant piece for the latest edition of The Spectrum Monitor entitled RTL-SDR: Your Eye To The Wireless World, February 2016. Here is a brief synopsis:

RTL-SDR Dongle: Your Eye to the Wireless World

By Mario Filippi N2HUN

The RTL-SDR dongle has garnered much popularity over the last several years as an inexpensive and effective broadband receiver for the radio enthusiast. Now Mario shows us how the RTL-SDR can be pressed into serving in other ways: as a rudimentary piece of test equipment to explore those countless wireless devices that power our world and make life convenient. You can use it when restoring vintage radios, doing frequency analysis, antenna analysis and a host of troubleshooting activities you may never have thought of.

I highly recommend buying at least the current issue ($3.00 / PDF Download – what a steal!) or better yet, subscribing for a whole year. Every issue gives far more value than the cost ($2.00/issue at the current subscription rate).

Mario’s article explores things I never would have thought of, and he explains how he uses these inexpensive dongles in place of much more expensive equipment. It is truly amazing what these little wonders can do, and Mario just keeps pushing back the envelope of what is possible.

Thanks Mario for a truly inspiring article – yet again you have given us even more rabbit trails to explore!

While Not Directly Radio Related . . .

While not directly radio related, this was too amazing not to share (so forgive me in advance! There is an Arduino involved, if that helps?!)

The video above is of a robot which can solve Rubik’s Cube in about 1 second.

I will not embarrass myself in telling how long it takes me to solve it . . . .

It is, however, easy to see how radio hobbyists could find these Arduino boards quite intriguing!

eBay Find: BANG & OLUFSEN BEOMASTER 900-K

beomaster900-closeWhile quite out of my price range, this is a beautiful piece of radio art nevertheless. (I recommend viewing the close-ups on the listing to really see it.) The receiver/amplifier has Broadcast, Long Wave, Short Wave plus FM, and the ability to reproduce beautiful stereo for its time, according to user reports.These were produced during the mid-sixties until 1970. I miss the artwork involved in many older radios as compared to today’s utilitarian radios. We may have better components and features, but we do not have the beauty or style in many cases.

I’ll be watching with interest to see how this auction ends!

A Review of Multipsk Software for Digital Modes and More

http://ak3q.com/wp-content/uploads/2016/01/MPSK2.jpg

Over the last year or so I have been using a really full-featured digital mode software called Multipsk, and it has become my go-to software for most digital modes. Back in September 2015 I wrote an extensive review of the software for The Spectrum Monitor (TSM) which Owner/Editor Ken Reitz has graciously allowed me to post on my blog at All Things Radio. Thomas has written numerous articles for TSM, and will attest to its emphasis on so many aspects of the radio hobby. If you are not a subscriber already you really do not know what you are missing!

The program boasts over 75 modes, not counting some of the many sub-modes or variations, and new modes are being added all the time. There is a free version and a registered version, with the paid mode costing around $45 (U.S.) The free mode will handle a lot of really great modes, but I confess, it was the additional “professional” modes which really made purchasing the registered version a must for me. Whichever way you go, you will not be disappointed. As I have noted on my blog and in the article itself, I consider the registration fee some of the best money I have ever spent for computer software.

As an added bonus, the free or registered version can be run on as many computers as you have in your home, and multiple instances of the program can be run on the same computer provided they are in separate directories. This is a great feature, and it means there is basically nothing going into the Windows registry file–the program runs right from the directory. My only problem is not having enough antennas to have as many instances of the program running as I would like!

I hope you will take time to read my review and then get the program–I think you will be suitably impressed as I was! (I have it running on XP machines through Win10, so compatibility should not be an issue.)

QSO Today Interview with Bob Heil

Bob-HeilEric over at QSO Today has posted an interview with Bob Heil, the founder of Heil Sound, whose microphones have transformed both the amateur community and the professional recording industry (Heil Sound is the only technology company featured in the Rock and Roll Hall of Fame!)

The interview is about an hour and half long, and I was fascinated with every minute. In addition to talking about how Amateur Radio laid the foundation for his incredible career(s), Bob also talks about the need for Elmers in the hobby and the need to get hams building again. Along the way there are tips about audio for both transmitting and receiving, as well as a bit of discussion concerning the science of phasing – these alone are worth the price of admission!

Here is the info from the QSO Today site:

Bob Heil, K9EID, is no stranger to ham radio, as a pioneer in audio systems, not only for the rock and roll stars in the 60’s and 70’s, but for ham radio as well. As the founder of Heil Sound, Bob’s injection of audio experience and know how has raised the bar of what is acceptable for good sounding voice communications on amateur radio. Bob shares his ham radio story with Eric, 4Z1UG, on this episode of QSO Today.
