Updated Raspberry Pi image for SDRplay software defined radios

(Source: SDRplay via Jon Hudson)

SDRplay is pleased to announce the availability of an updated Raspberry Pi3 image: This release (V0.4) is a complete image for the Raspberry Pi 3 with a range of pre-built applications for SDRplay devices.

Please note the following:

1. This software is made available purely for the convenience of users to save them from having to build the software themselves from source code.
2. All software apart from ADS-B is provided by third party developers and SDRplay can take no responsibility for any faults or bugs and is unable to provide support. For any support for these applications, we recommend that users contact the original authors.
3. Where the RSPduo is supported by applications, it can only be used in single tuner mode.
4. Whilst this should work with all RPi3s, we have only tested with RPi3 B+ and that will provide the best performance.

List of known issues:

SoapyRemote

Will only work over LAN connections and locally. It will not work over Wide Area Networks

CubicSDR
Will only support the RSPduo in single tuner mode

Gnu Radio
No known issues

GQRX
Some limitations with tuner hardware control
Audio only via USB and HDMI audio
CPU load is quite high and may cause audio stuttering

ADS-B
RSPduo not currently supported
Port B is the default port for the RSP2

Qt-DAB
Will only support the RSPduo in single tuner mode

TCP Server – This is a fork of the RTL-SDR (TCP) server developed by F4HH. This software should work with any client that supports the RTL-SDR (TCP) server software with some limitations. This software should be viewed as being for experimental purposes.
RSP2 works only on port A
RSPduo not supported
Maximum sample rate limited to 3.2 MHz
Some limitations with RSP1A RF gain control

Heartland America’s Grundig Executive Satellit deals

Many thanks to SWLing Post contributor, John Figliozzi, who writes:

I figure you’re the best source to get word of this out. Heartland America (1-800-229-2901) (www.heartlandamerica.com) is selling refurbished Grundig Executive Satellit receivers for $129.99 (MSRP $229.99).

The ad states “Factory serviced to meet original quality standards – may have slight cosmetic blemishes”.

It is Item No. 1Z-94828.

I have one of these I bought earlier this year on a similar deal from Heartland America. It works and plays perfectly and if there is a blemish, I’ve yet to find it. This is an excellent portable at a bargain price.

Excellent, John!  Thanks for the tip!

If elected, Labor commits to provide $2 million to restore ABC shortwave radio

Many thanks to SWLing Post contributor, Ian P, who shares the following story and interview via ABC News Northern Territory Country Hour. I strongly suggest listening to the full seven plus minute interview via the embedded audio player below:

If elected next year, Federal Labor says it will provide the ABC with $2 million in funding to help re-establish shortwave radio services across the Northern Territory.

The ABC controversially switched off its shortwave service in January 2017, and defended the decision by saying it would “only affect a very, very small amount of people” and save taxpayers up to $1.9 million.

The decision was heavily criticised by industry groups such as the NT Cattlemen’s Association (NTCA) and the NT Seafood Council.

NTCA president Chris Nott welcomed today’s announcement by Labor and said the ABC’s decision was short-sighted.

“What people take for granted in the cities is a luxury for those of us in the bush,” Mr Nott said.

“We rely on the HF shortwave radio transmitters because we don’t have mobile and data coverage for AM and FM radio stations.

“The ABC can expand its modern day platforms all it likes but the truth is we don’t all have access to it and the ABC did not care at all about the impact of its decision.”

Federal Member for Solomon Luke Gosling, said the axing of shortwave had angered a lot of people and community groups.

“Many thousands will benefit from this [bringing back shortwave],” he told the Country Hour.

“I was lobbied by a really large cross-section of the community that spends time in remote areas and when shortwave was cut there was a lot of angst, so it will be a good thing to bring it back to keep people on the land and waters connected.”

Many thanks, Ian!

SWLing Post Contest Question #2: A chance to win a piece of broadcasting history!

RCA Window from MI-7330

Last week, we announced a new contest to celebrate the SWLing Post‘s 10th Anniversary.

The prize is an amazing piece of broadcast history: a 75 year old round plate glass window that was fitted in the central main door of the RCA senders at the Woofferton, UK, transmitting site in 1943. This prize was generously donated by SWLing contributor and friend, Dave Porter (G4OYX).

Please read our original contest post (click here) which describes how you can enter to win.

The original post also contains the first of five contest questions which count as individual entries in the contest.

And now for our second question and second possible contest entry…

Radio Deal: Eton Field BT for historically low price of $70.99

Many thanks to SWLing Post reader, Christian, who writes:

Hi Thomas. Amazon have dropped the price of the Field BT yet again. This time to $70.99 shipped! This is now the lowest price I’ve ever seen for the Field BT. Perhaps they’re discontinuing the model? It’s a fine radio (very sensitive) with amazing audio. I paid a bit more for mine when it was on sale but I still think it was a good price. As I always say, this is Amazon so there’s no way to know how long this price will hold. I’m considering another one as a Christmas gift.

Thank you, Christian!

Alexa can now look up broadcast schedules with the Shortwave Signals skill!

Many thanks to SWLing Post contributor, Mark Hirst, who writes:

I’m pleased to announce that my Alexa skill has been approved by Amazon and is now available in the following countries:

Australia, Canada, the United States, and the United Kingdom.

Because single word skills are reserved for organisations and brand names, the skill name had to change and is now called ‘Shortwave Signals‘.

I’ve uploaded a video this morning with the finished skill in action:

Click here to view on YouTube.

Amazing, Mark! Thank you for developing this Alexa skill!

I’ve been beta testing Mark’s Alexa skill and have been very happy with the results. It makes for a nice hands-free way of checking broadcast schedules while in the shack. And it seems like only yesterday when Mark was tinkering around with the idea to create this skill.

Bravo for making Shortwave Signals a reality, Mark!

If you own an Echo or Alexa-enabled device, simply open the Alexa App and search for the Shortwave Signals skill to activate it.

We only have one Amazon Echo device in our house–the one I evaluated for my WiFi radio primer a couple years ago. As Black Friday approaches, I’m going to keep my eye on the Amazon Echo Dot for my radio room–the 2nd generation units are quite inexpensive (as low as $29.99 for a certified refurbished unit).

Contribute equipment to restore an authentic WWII B-17F heavy

Many thanks to SWLing Post contributor, Charlie Liberto (W4MEC), who shares the following:

Perhaps you could post somewhere a general call for anything WW II related that went into a B17F.

This website: http://hangarthirteen.org/ under the ‘Parts Drive‘ menu, lists the many things that will be sought after for the next few years. There might be those who monitor your site that have some of this just stored away, not knowing what to do with it or what will happen to it.

Ray is basically taking what was remaining, inspected, and approved as air worthy from this ditched plane, and building the aircraft to hook all the pieces together.

WOW! What an amazing project, Charlie!

I must say, Lucky Thirteen is in good hands.

Hangar Thirteen has chosen the best vintage radio restoration expert for the job! I’ve known Charlie for many years and not only is he an expert at restoring vintage gear, but he’s passionate about WWII era Signal Corps equipment. He brought my BC-348Q to life and patiently showed me how to align it. He also restored my Minerva Tropic Master and helped me fix the 3rd band selection on my beloved Scott Marine SLRM.

Charlie, I’ll certainly keep an eye out for the these components when I visit hamfests and will contribute anything I find or might have tucked away.

Post readers: If you happen to have any items needed in their list, please consider contributing it to the project and help this B-17F eventually have a fully-functional radio position. Of course, Hangar Thirteen is also in need of other aircraft parts–click here to check out that list.
