SDRplay RSP-1 OEM Metal Case

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

The SDRplay RSP-1 OEM Metal case is ready for order and shipment Worldwide

Includes:

1x Black aluminum metal enclosure with two labeled side panels, 1x Broadcast FM band-stop filter plus SMA Male to SMA Male barrel adapter,

1x Black semi-hardshell carry case,

1x Thermal pad to keep the RSP-1 cool and mechanically stable inside the enclosure and

1x Accessory set including enclosure screws, GND lug bolt set and 3M anti-slip rubber feet.
Can be used to upgrade the SDRplay RSP-1 ONLY to a metal enclosure. Helps block RF interference.

Note that owners of the very first RSP-1’s with F-Type connectors may require an additional F-Type pigtail adapter, or a MMCX to SMA pigtail to be able to use the BCFM filter internally. The BCFM filter can still be used externally.

Thank you, Rafman! I have the first generation RSP-1, so appreciate the note about using the filter internally via an adapter. That’s a nice enclosure.

eBay find: The Braun T-1000

Many thanks to SWLing Post contributor, David Korchin (K2WNW), for sharing a link to this Braun T-1000 on eBay.

With two days left on the auction and already 73 bids, I believe David is correct in assuming this radio might fetch upward of 900 Euro. Braun models certainly tend to fetch premium prices. The T-1000 is possibly my favorite Braun portable and I certainly wish I had one. I love Dieter Rams’ designs.

Note that shipping seems very modest at 6 Euro worldwide via DHL. I would check on that pricing prior to bidding if outside of Europe. This seller has a 100% rating with over 400 transactions on eBay. Again, thanks for the tip, David!

Any lucky SWLing Post readers own a T-1000? I’d love a review!

The first maritime radio distress call

(Source: The Telegraph via Mike Barraclough on Facebook)

On 17 March 1899, the East Goodwin Sands Lightship, operating under a licence from the General Post Office, BT’s predecessor, sent a signal on behalf of the merchant vessel Elbe, which had run aground on the treacherous Goodwin Sands off the coast of Kent.

The message was received by the radio operator on duty at the South Foreland Lighthouse, who was able to summon the aid of the Ramsgate lifeboat.

Goodwin Sands featured again a few weeks later when, on 30 April 1899, the East Goodwin Sands Lightship sent a distress message on her own account when she was rammed by the SS R F Matthews.

Rather than the now-famous signals of “SOS” or “Mayday”, the recognised call sign for ships in distress at the time was “CQD”. Devised in 1904 by the British Marconi Society, it was popularly mistaken to mean “Come Quick – Danger” or, more bleakly, “Come Quickly – Drowning!”. However, its actual official meaning came from the land telegraph signal CQ – “sécu” from the French word sécurité – followed by D for Distress.

The “SOS” Morse code signal – three-dots/three-dashes/three-dots – was established as an International Distress Signal, agreed at the Berlin Radio Conference on 3 October 1906 – though the signal wasn’t formally introduced until 1 July 1908.

ABC News: Portrait of a devoted shortwave radio listener

Saying goodbye to Radio Australia on the shortwave after 37 years

Kevin De Reus has lived in the same 24-kilometre-radius his whole life.

Born and raised in Iowa in the US, Kevin now calls his grandfather’s farm — just 12 kilometres from where he grew up in central Des Moines — home.

He is married, has five children and has worked at the same company for 20 years.

And while he admits he has not travelled much in his 52 years, it hasn’t stopped Kevin from listening to the news from Australia since 1980 — with the help of a shortwave radio.

Listening from the other side of the world

Even half a world away, he says the broadcast was one of the clearest of the stations he listened to.

“Radio Australia always held a special place in my heart just because it was in the South Pacific and I didn’t know much about that area — and the signal was always good from that part of the world,” he says.
“Most recently, over the last two to three years as I was listening in the morning hours here on 9.580, the signal was so good. It really was about the only English broadcaster at that time of the day that had news and information.

“Most mornings I would get up and turn on the shortwave radio at 7:00am (local time) and listen to the news from Australia and then I would drive to work.

“So many of the stations just aren’t on the air anymore. BBC doesn’t broadcast to North America anymore. I can’t even hardly hear the Voice of America in English anymore to tell you the truth. So Australia had the strongest signal.

“That’s why it was hard for me to hear [Radio Australia] was going to go off the air.”[…]

I believe Kevin De Reus did a fine job explaining the appeal of being a shortwave radio listener.

Though I gather a lot of international news these days with a WiFi radio (especially since Radio Australia left the shortwaves), I still prefer listening to shortwave.

It’s just how I’m wired.

KIMF: A new shortwave broadcasting station in Nevada

10 Replies

Many thanks to SWLing Post contributor, Tom Servo, who writes:

While going through the FCC Daily Digest for my own hobby website, I came across the International Authorizations section and happened to take a look today. To my surprise, a license to cover has been filed for HF station KIMF in Beowawe, NV! I can’t remember the last time a new HF station filed to go on the air in the US.

Do you know anything about this station? Here is a link to the FCC’s data page on the station; I’ve attached a PDF copy of the license form, which lists both the operating frequencies as well as times, power and modes they’ve asked for. It looks like they will run a combination of AM and USB across three frequencies.

[…]I went to the license coordinates to see if anything was visible on Google Satellite View, but it’s just empty desert. So I have no idea what’s really going on, but generally once a license to cover is filed, that means the station is built and ready to go on the air. At least in the world of AM, FM and TV broadcasting!

Here’s the frequencies/times/power/mode listed in the PDF, in case you can’t view it:

6065 kHz – 01-06 UTC 50 kW AM
9300 kHz – 08-12 UTC 100 kW USB
13570 kHz – 00-04 UTC 100 kW USB

Anyway, I figure you or one of the intrepid readers of your blog will have the scoop. Thanks for your time!

Wow–many thanks, Tom! This filing catches me by surprise as well, but it does ring a bell. Perhaps an IMF representative contacted me in the past or I met someone from IMF at the Dayton Hamvention? I simply can’t remember.

Based on the application, IMF had to file for an extension due to several delays in building the transmitter site in Nevada. I’m guessing the Google satellite imagery was taken before site construction began.

It appears International Missions Fellowship (the parent organization who is filing this FCC application) currently operate the Radio Missiones International station in Tegucigalpa, Honduras on 3340 and 5010 kHz.

Here’s a note about the Nevada transmission site from the IMF website:

In the USA we have purchased a property near Battle Mountain, NV where we are working to build a powerful Shortwave Station which will be beamed at Mexico and Asia. It can be heard also in North America. We plan to build more stations after this. We have also just built a radio control center and small studio in Corona, CA to send programs to these transmitters via satellite/internet. It is now in operation. You can hear KIMF by clicking on the IMF Missionary Radio link below.
