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

Lots happening with KiwiSDR – there are now over 130 live 0-30MHz fully controllable SDRs scatted around the world some in really interesting locations. Using Kiwi’s around the world is like being able to go on a exotic DXpedition any time.

Here (attached graphic) is a map of the current locations, you can see the live status of online receivers here:

and as a list of receivers here:

KiwiSDRs now include HF Fax reception natively, just select Fax in the Extension menu, select the part of the world you are interested in and the Kiwi will tune the weather fax frequency and receive the weather fax all natively (no extra software needed) – too easy!

Lots more great things happening.

Here is the latest news…

Thank you for the update, Mark! I had no idea the KiwiSDR app had an HF Fax extension. After reading your message, I loaded a KiwiSDR session in Europe and used the Fax feature. It couldn’t have been easier. The screen grab (above) came from my first attempt.

The KiwiSDR network is truly amazing. I use it all the time–especially if there’s an important broadcast happening and I can’t easily receive it at home or while traveling. As an example, during the recent French elections, I listened to results roll in on France Inter mediumwave from a KiwiSDR in Italy. It felt like being there.

My one feature request would be that the KiwiSDR app include some form of native broadcast recording like the WebSDR at U Twente.

Many thanks for the update, Mark!

Would you like to host your own KiwiSDR?

The whole system only costs $299 US. The KiwiSDR site has a list of distributors around the world.

Amazon has units in stock at $299 US shipped.

I would have purchased a KiwiSDR ages ago–during their Kickstarter campaign–if I only had the Internet bandwidth at home to support it. My Internet speeds are likely lower than anyone else here in the SWLing Post community. One of the compromises living in a relatively remote spot with no RFI. 🙂

Kyodo News Agency Fax and the Sony CRF-V21

My friend, @K7al_L3afta, posted to Twitter, the following fax he decoded from the Kyodo News Agency on 12,745 kHz today:
KyodoNewsAgency-001

The Kyodo News Agency is possibly the last marine weather fax station which faxes daily news (full newspapers) and navigational warnings to ships at sea.

PL-660For those of you who might believe it takes a sophisticated setup to decode a FAX transmission, you would be incorrect. @K7al_L3afta uses only a Tecsun PL-660 portable hooked up to his PC running the MultiPSK application. He lives in Morocco–in an urban environment with lots of RFI as well, so those of you living in a similar situation should feel encouaged.

After posting the FAX image, our friend @LondonShortwave then sent a link to a Sony radio I have never seen before: the Sony CRF-V21.

The Sony CRF-V21 (Image source: Universal Radio)

The CRF-V21 is a full-featured shortwave radio receiver with built-in printer and decoding for FAX and RTTY. In fact, with an optional AN-P1200 satellite antenna, the CRF-V21 will even copy and print G.O.E.S. satellite weather transmissions.

Here is Universal Radio’s archived description of the CRF-V21:

The Sony CRF-V21 Visual World Band Radio is the first portable to offer integrated facsimile (FAX) and radioteletype (RTTY) shortwave reception. You can print RTTY and FAX transmissions directly with the built-in thermal printer. Supported RTTY modes include Baudot at 60, 66, 75 and 100 WPM and ASCII at 110, 200, 300 and 600 bps. FAX shortwave speeds include 60, 90 120 and 240 rpm. Even G.O.E.S. satellite weather transmissions may be copied and displayed with the optional AN-P1200 satellite antenna.

Frequency coverage is 9 kHz to 30 MHz for all longwave, medium wave and shortwave frequencies. Plus FM coverage from 76 to 88 MHz and NOAA satellite channels 137.62/141.21 MHz. The optional AN-P1200 antenna system adds 1.6910/1.6945 GHz G.O.E.S. satellite reception. Another highlight of this radio is built-in spectrum display showing a visual picture of 200 kHz or 5 MHz of the shortwave spectrum.

Other refinements include:   Mini Earphone Jack, S Meter, 350 Alpha Memories, Carry Handle, Clock, 8 Event Timer, Scan, Sweep, FM AFC, Synchronous Detection, Attenuator, 6/3.5/2.7/14 kHz Selectivity, AF Filter, Record Jack, Dial Lamp, Keypad and LCD Contrast Adjustment.

The CRF-V21 is supplied with:  AN-V21 telescopic antenna unit, ACP-88R AC power unit, NP-227 battery, BCA-70 charge tray, antenna cable, protective cover, UPP-21 thermal printer paper and manuals. Operates from 110/120/220/240 VAC. Requires two AA cells for memory retention. 16.25 x 11.25 x 6.75 inches (21 lbs.).

The CRF-V21 is basically an all-in-one Holy Grail portable for those at sea!

@LondonShortwave also shared the following video of the CRF-V12 in operation:

Simply amazing. I love the display–reminds me of the Eton E1. I would expect excellent audio out of this rig as well.

When I checked today, there wasn’t even one CRF-V21 listed on eBay–not even as a completed listing. I imagine they are rare indeed.

Out of curiosity, do any SWLing Post readers have a Sony CRF-V12 in their collection? I would certainly like to add one to mine someday.

Many thanks to my friends @K7al_L3afta and @LondonShortwave for this radio diversion today!
