Dutch regulator removes broadcaster’s antenna

It is reported the Dutch Radiocommunications Agency dismantled the antenna of a legally operating broadcast station

It appears they thought Vechtdal NL in Ommen on 105.6 MHz was a pirate but the station, an associate of Vechtdal FM, was correctly licenced. The Agency says that something went wrong with the checking of licences.

The antenna was on the watchtower of the State Forestry Besthmenerberg Ommen near Nieuwleusen. It is unclear if the Radiocommunications Agency will pay compensation for the damage.

With switch from AM to FM, some Polynesians now in the dark

(Source: Southgate ARC)

Some inhabitants of French controlled Polynesia are unhappy at the switch over from Medium Wave AM to VHF FM broadcasting

Radio New Zealand reports Radio Polynesie Premiere switched to an all FM service at the beginning of December, leaving pockets of inhabitants in valleys and on remote atolls without any local radio service.

The broadcaster added five FM transmitters to its network of 48 to improve its reach but in an area the size of Europe, the signal fails to reach all communities.

Concern has been expressed that vital weather warnings are no longer heard.

The mayor of Makatea in the Tuamotus Julien Mai said there is a risk to public safety because people have always been advised to have an emergency kit that includes a radio when severe weather strikes.

Norway becomes first country to go “fully digital”

(Source: RadioInfo via Kris Partridge)

11th January 2017 is a historic day for the medium of radio.

Norway becomes the first country in the world to move towards fully digital radio transmissions. As a result of this, the national FM network will be switched off.

The FM networks will be switched off region by region, starting in Nordland 11th January. The event will take place in Bodø and the final switch-off will be done at 11.11 pm CET.

The heads of NRK radio and commercial radio will be in Bodø to represent the Norwegian radio industry. Also, head of BBC radio, Helen Boaden, and head of radio at EBU, Graham Dixon, will attend.

An international seminar for European broadcasters will be held the day before the historic move to FM switch-off and an international press-conference will be broadcast on radio.no at 2 pm CET.

The final program will be published nearer to the event.

Brian FM: a post-disaster FM radio station in New Zealand

Radio ‘nutters’ move in to help shaken Kaikoura

A fortnight after the Kaikoura earthquake, most of the businesses along West End, the town’s main street, are still closed – the interiors darkened, some shopfronts cordoned off.

But the door of one of those shopfronts is open, and from it, the strains of Brian FM come floating out.

Who’s Brian?

“I have no idea,” Chris Diack says.

“People are wanting to walk in and talk to Brian all the time and there’s no Brian – there’s Chris and Robert.”

Mr Diack and his offsider, Robert Jeffares, have been broadcasting from their makeshift studio for a week now, after convincing the owner of a local frequency that was not being used to let them take over.

The content is mostly “parish pump information”, says Mr Diack – the level of detail the rest of the country might not need to hear but which is invaluable to locals trying to find out where their next hot shower might be coming from.

“The water’s off, you can’t use the toilets, if you need to use the toilets use the portaloos, and where are they … Four Square’s open at midday, get along there and get some milk, bread and butter… You couldn’t buy butter for love nor money in Kaikoura.”

In between broadcasting the minutiae of post-quake life, they conduct interviews with the district mayor, civil defence, the Salvation Army, and errant RNZ reporters who wander in to the studio.[…]

Aeronautical SDR: Ivan’s in-flight FM spectrum captures

Aircraft-Jet-Boeing-VOLMET

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

Thomas, not sure if this is something relevant but airlines now state it is OK to use an am/fm radio on board aircraft.

Not much possibilities for AM unfortunately but on a recent flight from Ft Lauderdale to Dallas and Albuquerque I hooked up an SDRPlay receiver to a 3 inch stick antenna and recorded a few stations I was able to pick up along the way.

The first video is posted here:

I did take a few more videos flying between JFK and MIA as well.

I used the following equipment:

fm_dx

1. 13 inch laptop that I also use for work
2. SDRPlay receiver
3. Old scanner antenna that I happened to have
4. SDRUno software to drive the radio
5. Screen recorder that comes with the Win 10 Xbox app
6. Windows movie maker to stitch the individual clips together and annotate

If needed, the size of the setup above can shrink further if a smaller laptop/tablet is used and an RTL dongle instead of SDRPlay.

You will also need to equip yourself with a window seat. Otherwise, signals are significantly weaker.

I did not place the antenna in a special position, just next to me on the seat where it could not be noticed by other passengers. I uploaded a few more videos from my weekly shuttle flights between MIA an JFK.

Wow!  Thanks so much, for sharing this, Ivan.

I’ve always packed a simple FM-capable radio in my one, compact carry on bag and typically try a little FM DX travel while in flight. I was never aware there was a restriction on using an FM receiver in flight, but I’ve always kept my radio listening very discrete so it’s never been a problem.

I love the idea of doing in-flight FM spectrum captures! It would be fun to watch signals on the spectrum shift and change as the flight progresses. Very cool, Ivan!
