Video: Fenu demonstrates the BELKA-DSP receiver

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following video demonstration of the BELKA-DSP receiver by Fenu Duarte:

Thanks for sharing this, Dan.  I must admit, it seems the BELKA-DSP has some excellent receiver characteristics. I like the backlit display and the rugged, simple form-factor. It doesn’t have an internal speaker, but based on Fenu’s video, the audio sounds superb (especially if you’re using a quality amplified speaker like Fenu).

I had planned to review the little BELKA-DSP last fall, but simply had too many in-bound review transceivers. As I knock out some of these reviews, I might have to reconsider!

Alex Buevsky kindly supplied the English language manual for the BELKA-DSP last year. If interested, click here to download the PDF.

TX Factor Episode 25

Many thanks to SWLing Post contributor, Eric (WD8RIF), who notes that the 25th episode of TX Factor was recently released. Here’s the show summary:

A post-election special – well, not really! Just a look at some more new and innovative AR products from this year’s Hamfest, including a potted history of the ever-popular and much revered range of transceivers and kits from Electraft with co-founder Eric Swartz WA6HHQ. There’s our free-to-enter draw with some excellent prizes from ML&S and RSGB to be won.

In this modern era of connectivity, we take the ever-present Internet for granted; it’s always there and continues to deliver our data from A to B without issue. But what would happen if that vital link failed? We visit Southampton and Portsmouth on the UK’s south coast to see how two city councils, assisted by a group of dedicated amateurs, plan to maintain their communications infrastructure via radio links alone, should the Internet go down.

Now Unblocked: Watching the new Radio Australia documentary

Yesterday, we posted a note about the new documentary, “Australia Calling: 80 Years of International Broadcasting.” At the time, I mentioned that the video was geo-blocked–meaning, you could not watch the video outside Australia without using a VPN.

Many thanks to SWLing Post contributor, Peter Marks, who shares this great news:

I’ve corresponded with the iview team and they have un-geoblocked the video. It can be watched here:

https://iview.abc.net.au/show/australia-calling-80-years-of-international-broadcasting/video/NC1940H001S00

I tested it over a VPN to Singapore and it played for me.

Thanks so much, Peter! I’ve loaded the video with no problems here in North America.

Restoration of a USN version of the ARC-5 command set receiver

(Source: Southgate ARC)

Gregory Charvat N8ZRY writes on Hackaday about an un-modified-since-WW2 surplus CBY-46104 receiver with dynamotor.

He writes:

I’ve been told all my life about old-timey Army/Navy surplus stores where you could buy buckets of FT-243 crystals, radio gear, gas masks, and even a Jeep boxed-up in a big wooden crate. Sadly this is no longer the case.

Today surplus stores only have contemporary Chinese-made boots, camping gear, and flashlights. They are bitterly disappointing except for one surplus store that I found while on vacation in the Adirondacks: Patriot of Lake George.

Video description: Repair and restoration of a USN version of an ARC-5 command set receiver. This model covers 1.5-3 Mc, runs off its original dynamotor, with no internal circuit modifications. This radio is original with the exception of a small number of caps that tested bad which were re-stuffed. Build date is Feb. 42, who knows where and what this radio may have been involved in?

I’ve always wanted a functioning ARC-5 command set to accompany my BC-348-Q receiver. This article has inspired me.

Post readers: Anyone own a functioning ARC-5 (or any variants)? Please comment!

1961 Film: “Tuning In Radio Sarawak”

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

Hi Thomas, I just watched this very interesting DX film about RADIO SARAWAK.

It’s a behind the scenes look at radio in the tropics, with great vintage gear.

I don’t think it was FM as it’s was much expensive and coverage is limited. But on the other hand we don’t see the large MW antennas

What do you think?

Click here to view the film at the Imperial War Museum website.

Good question, Adid. The FM band wasn’t widely included on radios until the late 1950s and early 1960s. Since this film dates from 1961, I imagine some of those new transistor/valve radios could have included FM, although I imagine mediumwave was the choice band for regional broadcasts.

Hopefully, an SWLing Post reader can shed some more light on Radio Sarawak’s history! Please comment!

EDXC conference featured on Andorra TV

The EDXC conference was held in Andorra this year and I wish I could have attended. When I lived in Europe, Andorra was one of those destinations always on my bucket list in no small part due to my affinity for Radio Andorra.

EDXC attendees–many are regulars here on the SWLing Post–were treated to a hands-on tour of RTVA and even featured in the news. Check out the following video:
