SDRplay has added sample IQ files to their website

Many thanks to Mike Ladd at SDRplay who notes that they have added a new IQ Demo Files page to the SDRplay website.

Here’s the intro:

IQ Demo Files

Here you can find off air IQ recordings for you to check your SDRuno and related software settings for a variety of different situations.

If you don’t already have an RSP, because these demo files have been recorded using an RSPdx, you can get to see and hear exactly how SDRuno works in conjunction with an RSPdx. Simply download a copy of SDRuno from https://www.sdrplay.com/sdruno/ and follow the instructions below to select the WAV file input using one of the IQ files below. (Please note these are not traditional audio “WAV” files – the WAV format is used as a wrapper to contain these very large data files (100s of MBytes) containing the stream of data normally exchanged over the USB cable between RSP and computer)

If you have an RSP and are configuring software for specific types of signal decoding, we have included a number of sample IQ demo recordings you can use to check your setup before looking for real world signals.

Ron reminds us that MFJ still offers a shortwave radio kit

Following up on our recent MFJ post, SWLing Post contributor, Ron, writes:

Another thing about MFJ is they still offer the MFJ-8100 as a kit or built. This is the only regenerative receiver available as far as I know.

Mr. Jue and his guys did a couple of tweaks like limiting band coverage to insure stability, using 1/8 inch 3.5mm stereo phone jacks and use an LM386 audio IC to drive headphones or speaker.

The whole thing is in a metal enclosure to minimize hand capacitance found in most regens.

The QRP crowd likes to use the 8100 with flea power CW rigs, it’s that good.

And it’s been in production far longer than the Heathkit GR-81 or any of the Knight Kit regens, too.

Thank you for sharing that, Ron! I had completely forgotten about this little kit when someone recently asked about the availability of Ten-Tec regen receiver kits (that are, sadly, no longer on the market to my knowledge)! I might have to grab one of these kits–looks like a fun one to build.

Click here to check out the MFJ-8100K.

By the way, I also believe the NM0S Ozark Patrol regen kit is still available from the Four State QRP Group. Click here to check out the product page. It doesn’t have a metal enclosure like the MFJ, but it’s also a fun kit to build.

Hurricane Watch Net to Activate as Paulette Bears Down on Bermuda

The Hurricane Watch Net (HWN) has announced plans to activate today (Sunday, September 13) at 2100 UTC on both 14.325 MHz and 7.268 MHz as Hurricane Paulette is predicted to make landfall on Bermuda early on September 14 as a Category 2 storm. HWN Manager Bobby Graves, KB5HAV, noted that activation plans are subject to change as weather forecasts unfold.

As of 1500 UTC on Sunday, Hurricane Paulette was moving to the northwest toward Bermuda at about 14 MPH, with strong winds, storm surge, and heavy rain expected to begin there by evening, the National Hurricane Center (NHC) reported. A hurricane warning is in effect for Bermuda. Paulette was some 240 miles southeast of Bermuda, with maximum sustained winds of 80 MPH.

“Monday morning, after landfall, we will do what we can to gather weather data and damage reports while operating on both 20 and 40 meters,” Graves said. “Once we’ve completed operations for Paulette, we will switch gears and begin operations for Sally immediately.

The HWN will be on 20 meters during daylight hours, switching to 40 meters in the evening, although propagation could dictate going to 40 meters during daylight as well.

Tropical Storm Sally is forecast to become a Category 1 Hurricane on September 14, with landfall expected on the evening of September 15, somewhere along the coast of Mississippi.

“Of course, should the forecast track be adjusted to the left or right of the current track, landfall timing and location will change,” Graves noted. “Everyone in the forecast path of Sally should follow the directions of local emergency management.

[…]WX4NHC at the NHC will also activate on Sunday, September 13, at 2100 UTC for Paulette and Sally and will remain activated until 1900 on Tuesday, September 15, monitoring and gathering reports from the HWN on 14.325 and 7.268 MHz and via the VoIP-WX Net on Echolink WXtalk 7203 Conference and IRLP 9219.

TuneIn ruling may lead to a more restrictive future for UK smart speaker and Internet radio users

Many thanks to SWLing Post contributor, David, who writes:

I live in the UK and, like many of your readers and contributors, one of the aspects of the radio hobby I enjoy is ‘content DXing’. As of yesterday [September 9, 2020], all of the US-based classical music stations and even some European news outlets are no longer available through TuneIn.

This appears to be because of a court ruling which identifies TuneIn as a ‘broadcaster & communicator’ rather than – as TuneIn itself claims – an indexer of available stations.

I’m assuming Direct Streams from each station are still available but I can’t help but worry that station aggregators might also be in the firing line at some stage.

Thank you for sharing this, David.

Implications Beyond TuneIn?

At first blush, one might think this ruling only applies to TuneIn users, but it certainly sets the stage for further law suits since TuneIn isn’t the only “audio guide service” accessible in the UK.

Check out this article David shared from November 2019 when the ruling originally took place:

In 2017, Sony and Warner sued US-based radio service TuneIn, claiming the company infringed its copyrights in the UK. A judgment handed down today by the High Court states that while TuneIn does not offer content itself, the provision of hyperlinks to content not officially licensed in the UK constitutes a communication to the public and is therefore infringement.

TuneIn is one of the most prominent and recognizable providers of radio content in the world.

Available for free or on a premium basis, the service offers access to well over 100,000 radio stations and millions of podcasts. It doesn’t provide this content itself but acts as an indexer (“audio guide service”, according to TuneIn) for those looking to access third-party streams.

In 2017 it emerged that Sony Music UK and Warner Music UK had sued the US-based company in the UK, claiming that since many of the TuneIn-indexed stations are unlicensed to play music in the region, linking to them amounts to infringement of the labels’ copyrights.

Today, the High Court of England Wales handed down its decision and it doesn’t look good for TuneIn. The judgment begins by stating the opposing positions of the labels and TuneIn, which are particularly familiar in these types of disputes concerning hyperlinking.

“The claimants say that a finding for the defendant will fatally undermine copyright. The defendant says that a finding for the claimants will break the internet,” Justice Birss writes.

The labels argued that TuneIn needs a license, an assertion “strongly disputed” by TuneIn. The company argued that it does not “store any music, and merely provides users of TuneIn Radio with hyperlinks to works which have already been made freely available on the internet without any geographic or other restriction.”

In other words, TuneIn presents itself as not unlike Google search but instead of indexing websites, it indexes and links to radio streams. However, Justice Birss declared the service to be “much more than that”, in part due to its curation and search features.

“I find therefore that the activity of TuneIn does amount to an act of communication of the relevant works; and also that that act of communication is to a ‘public’, in the sense of being to an indeterminate and fairly large number of persons,” he writes.[]

Indeed, this is essentially what all station aggregators do: they index, curate, and make streaming audio content readily available via Internet media devices like WiFi Radios.

While most WiFi radio station aggregators don’t have the app and web browser-based following and popularity of TuneIn, they do offer the “curation and search features” which lead Justice Birss to side with Sony and Warner.

UK Sonos Users Affected

David also points out complaints from Sonos users in the UK who have been directly affected by the TuneIn ruling. One Sonos owner commented:

Dear Sonos: can you see the enormity of the damage that’s been inflicted to your product? A major feature of the product has been devalued – at least for UK customers. Internet radio is 90% of what I use Sonos for; 80% of my listening is non-UK. Stopped working overnight. And you seem to be just as surprised as I am. How come you didn’t see this coming? You send me an email whenever you have something new to sell. Why didn’t you send me an email to warn me that this predictable event was going to hit me? You don’t seem to have a mitigation plan. You don’t have a how-to-workaround or this-is-what-we-are-doing-to-fix-it article in an prominent place on your web site.

Note that it’s not only TuneIn that’s now broken but also Sonos Radio. “Sonos Radio is an Internet radio service, exclusively available on Sonos. It features 60,000 radio stations from around the world”, it says on the tin. No it doesn’t anymore. They are still all there but they don’t work when you click on them.

From Sonos’s vantage point, TuneIn may be a separate entity. But that’s irrelevant from my point of view. I want the functionality that the product promises.

OK there may be some workarounds. I’m sure I’ll find them. But the fact remains that a major feature of the product no longer “just works”. It can still be “made to work”, but that takes a certain level of cyber-literacy.

I’m willing to bet UK users of other streaming media devices and smart speakers–especially devices from companies who aren’t in the business of directly streaming copyrighted music–will eventually have a smaller selection of international content.

Is there a work around?

Surely. But it could require heavy use of a VPN or similar service to trick TuneIn, Sonos, or other Internet devices into believing they’re physically located outside the UK. This may only be a temporary fix, however. Both Netflix and Amazon Video streaming services, for example, began effectively blocking most of the major VPNs a few years ago.

Have you been affected?

To be clear: I’m no expert in streaming media law, so what I’ve presented here are the basics and user reports. These are my own opinions and assumptions about where this ruling could lead.

If you live in the UK and have been directly affected by this ruling, we’d appreciate your comments.
