Pirate Radio Recordings: Two short UNID broadcasts

1-RadioListening2

“Wow–those were short!”

I was travelling Saturday night, but had the foresight to set my WinRadio Excalibur to record the pirate spectrum. There were few pirates on the band–less than I would have expected to hear on a holiday weekend in the US–and some of them were plagued by a local broadcaster whose spurious emissions wiped out the whole band at times.

I did catch a couple of interesting unidentified broadcasts, most likely transmitter tests as both were very short.  The first broadcast came on around 3:10 UTC (Jan 20) and consisted of two songs, ending with the Tardis sound effect from Dr. Who.

The second broadcast came on just after 7:00 UTC and consisted of only one song–no IDs at all. I would suspect this was the same pirate; however, the first broadcast had a tinny sound that this broadcast lacked. Indeed, their USB signal was quite amazing (wish s/he would have broadcast a full show).  Click here to download the recording, or listen via the player below:

Please comment if you think you can ID these broadcasts.

Toyota is developing a shortwave-driven car?!?

Though I’ve always believed that the shortwave spectrum is a medium–a conduit for international communications  not simply confined to analog audio broadcasts–I would have never guessed it would be used in an autonomous vehicle technology system. But check this out (and see update/comments below, plus our follow-up post):

Toyota and Audi turned heads earlier this month by announcing that they were following in Google’s tracks and developing partially self-driving, or “autonomous” vehicle technology systems of their own.

At that time, Toyota noted in press materials that it has been testing one such semi-autonomous vehicle system — the Intelligent Transportation System (ITS), which uses short wave radio signals to have cars communicate with other vehicles and surrounding infrastructure to avoid collisions — at a simulated city inside its Higashi-Fuji Technical Center in Susono City, Japan.

Toyota also said that further “research and development will continue at Toyota Research Institute, North America (TRiNA), in Ann Arbor, Mich.” […] Read the full article on TPM.

Update: Sean (@VA5LF) commented on Twitter, “wow, that sounds ill-advised. HF is no place for local area comms!”

I wholeheartedly agree, Sean. The use of LED traffic lights alone bombards my car’s AM radio with Radio Frequency Interference (RFI). I can’t imagine my life depending on a technology that is so vulnerable to RFI. I would assume Toyota has a way to overcome this, else this info is simply incorrect/inaccurate. I mean, imagine how geo storms or skip would effect local driving conditions. 🙂

Reader comments:

One commenter noted:

“I didn’t know that VHF, UHF, or 5.9 GHz bands were considered short wave.”

Then Mike sent a message with the following comment:

I was just reading the posting about Toyota and self driving vehicles and the mention of “short wave radio signals”. I wonder if some how they meant “near field communication (NFC)”  and it has been translated to short wave (near field – short distance) radio communication? NFC is a proven technology being used for payment systems etc.

Just wondering aloud.

Indeed. I strongly suspect this journalist got their terminology a little skewed! Check out our follow-up post.

Shortwave Radio Recordings: Radio Romania International

RRI-RadioRomaniaInternationalRadio Romania International is on of my favorite international broadcasters. I routinely listen to their broadcasts in English and French. With the demise of Radio Bulgaria in 2012, I turn to RRI for news not only about Romania, but Eastern Europe in general.

I do fear for the future of Radio Romania International on the shortwaves as so many broadcasters are pulling out of the spectrum and putting all of their faith into online “broadcasting.” If you enjoy RRI as much as I do, consider submitting a reception report and letting them know that you’re listening.

Tuesday, I recorded RRI’s English broadcast from Tiganesti on 9.435 MHZ (21:30 UTC)–quite an easy and reliable catch in eastern North America. You can click here to download the recording as an MP3, or simply listen via the embedded player below:

The Mighty KBC testing fast digital modes this weekend

The Mighty KBC will broadcast this Sunday (January 20) on 9,450 kHz between 00:00-02:00 UTC (that’s Saturday night in North America from 19:00-21:00 EST). Details below:

We will try some fast text modes this weekend on The Mighty KBC, to see if they can survive the rigours of shortwave.

This will be during the North America broadcast at 0000-0200 UTC 20 January on 9450 khz. At about 0130 UTC, 4XPSK63R will be centered on 1000 Hz and MFSK64 centered on 2000 Hz. (For 4XPSK63R, use Fldigi 3.21.65 or newer: OpMode > PSKR > MultiCarrier > 4XPSK63R.) At just before 0200 UTC, MT63-2000 (long interleave) will be centered on 1500 Hz, and PSKR250 on 2800 Hz. This will be an Flmsg formatted transmission, with html. Fldigi and Flmsg can be downloaded from www.w1hkj.com.
