Many thanks to SWLing Post contributor, Alexander (DL4NO), who shared a few notes with me from his visit at the Friedrichshafen Ham Radio convention. Alexander has kindly allowed me to post his notes here on the SWLing Post. Alexander writes:

The first booth I visited was of Dokufunk (http://www.dokufunk.org/). They collect QSLs and other information about wireless history for scientific evaluation. Its head Wolf, OE1WHC, was a moderator for the Austrian shortwave service which does not exist anymore. But ORF still supports Dokufunk. They have a large archive and even the equipment to digitize large quantities if information. I brought them a package of ham radio periodicals, mostly issues of DL-QTC, the predecessor of cqDL, and got some QSPs (magazine of OEVSV) back. I collect those periodicals to gain and provide access. Seehttp://www.dl4no.de/thema/amateurfunk-zeitschriftenarchiv.htm, catalog at the bottom.

The flea market filled three exhibit halls. If you needed a tube heating for your shack you had a wide choice, from radios to ham equipment to scopes. On the newer side you could get Windows XP packages with the appropriate hardware.

Yaesu, Icom & Co where there, of course. A large part of Hall 1 had booths for most of the European ham radio societies and other entities. Several attractions for the youths were there: A fox hunt around the hall, possibilities to solder simple circuits and more. The exhibit center even provides a kindergarden.

Hamradio had lots of presentations. The “SDR Academy” run all over Saturday – completely in English. See http://www.sdra-2016.de. Last year’s presentations are on Youtube. Search for “SDRA-2015”.

My presentation was titled “HAMNET On 70 cm – Possibilities and Limitations”. I should explain that HAMNET is our way to use the 44.0.0.0/8 TCP address space reserved for Ham Radio use. Starting in Germany and especially Austria we use more or less standard WLAN equipment to build a ham radio intranet. User access is mostly on 2.3 GHz and links on 5 GHz. Where we have gaps in the wireless coverage we use Internet wormholes. This way you can access for example packet radio sites in Canada. See http://hamnetdb.net.

2,3 GHz and up means exclusively line-of sight connections. Quite some OMs cannot reach access points this way. The only alternative up to now has been VPN connections through the Internet. I think we could provide relatively fast access on 70 cm. Here in Germany we have two 200-kHz channels for such uses. They were defined in the 1980s for packet radio access up to 76 kbps. This technology is next to dead.

Theoretical calculations show that we could provide up to 1 Mbps and cover up to 50 km if we use modern modulation schemes. You could even improve throughput by making TCP/IP less gossipy. I proposed to use SDR blocks like HackRF or LimeSDR and combine them with a RF frontend (filter, preamp, PA, fast switching). The hardware is more or less readily available, but this is mostly a software topic. While HAMNET relies on standard WLAN equipment with all its limitations for ham radio usage, this system could be completely open. We could it adapt to all our needs and ideas. In the end we could port it back to the microwave bands.

Even if we only work on the lowest protocol levels this will pose quite some challenges. We would need programmers with quite varied expertise from TCP/IP protocols to SDR technology. My presentation was to attract such people. Personally I will not program anything. As a technical writer with a quite wide expertise I might be a bracket for the project and write documentation for it.

At the opposite end of the exhibit center another fair went on, called Maker Faire. In former times you would have called it “make it yourself”. The exhibits there went from computer modding to 3D printing, knitting and also ham radio. For this I modified my presentation a bit: “WLAN Below 1 GHz – Do You Want To Program For It?” The technology I talked about is near hot topics like Internet of Things or traffic telematics.

New Managing Director of ABC signals a return to international broadcasting

Radio-Australia-BannerMany thanks to SWLing Post contributor, Phil Brennan, who writes:

The following piece regarding Radio Australia caught my eye last week. It was authored by Hamish McDonald and appeared in the 18 June 2016 edition of the Saturday Paper.

[McDonald] reports on a variety of foreign policy matters from an Australian perspective:

“Guthrie’s world view

Our mole at the ABC tells us new managing director wants to pull back from the embrace of the Chinese Communist Party’s Publicity Department, as the Ministry of Propaganda is known.

In her first meeting with the board on June 9, Guthrie questioned the value of the ABC’s Chinese language portal, AustraliaPlus.cn, which has been pinged by the ABC’s own watchdogs for pulling awkward content to avoid displeasing the CPC.

We are told she also “forcefully expressed” her interest in the corporation returning to full-blooded international broadcasting, and raised the fact that Radio Australia no longer broadcasts in Mandarin, nor in Tok Pisin, the lingua franca of Papua New Guinea. A return to international TV broadcasting two years after the Abbott government scrapped funding for the ABC’s Australia Network (to please Rupert Murdoch) would not come cheap. Nor would a revival of Radio Australia, once the major arm of Australia’s soft power in the region.”

I also spotted a reference to this meeting of the new ABC MD in a previous issue by another columnist which seems to be outside the paywall. Click here to view.

Many thanks, Phil, for sharing this! As I’ve mentioned before, Radio Australia is a staple source of news for many.  I hope Guthrie does, indeed, re-focus on their international content and all forms of delivery.

Icom IC-7300: Field Day reports?

Icom-IC-7300-Front

I’m curious: any Post readers use the new Icom IC-7300 on Field Day?

While I gave Icom’s new transceiver a very positive review, it was based on operation at my home QTH. There were no significant contests in progress during my review window.

Field Day has, arguably, some of the toughest receiver conditions out there.  If a transceiver/receiver performs well during Field Day’s dense signal environment, without overloading or distorting, it’s a good receiver.

I’m very curious if anyone tested the IC-7300. I assume someone took it out to play on Field Day!

Please consider commenting with your report!

Listening across the globe: 2016 BBC Antarctic Midwinter Broadcast!

1024px-Antarctica_6400px_from_Blue_Marble

On Tuesday, 21 June 2016, the BBC World Service officially transmitted the 2016 BBC Antarctic Midwinter Broadcast–an international radio broadcast intended for a small group of scientists, technicians, and support staff who work for the British Antarctic Survey.

This is one of my favorite annual broadcasts, and I endeavor to listen every year. Once again, the SWLing Post called upon readers to make a short recording of the broadcast from their locale.

Below are the entries, roughly organized by continent and country/region, including reader’s photos if provided. I had planned to post these recordings by Sunday, but my travels interfered and I discovered an additional ten recordings in my inbox! (If I’ve somehow missed including your entry, please contact me; I’ll amend this post.)

So, without further ado….

Mark Hirst’s listening post.

SWL: Mark Hirst
Location: Basingstoke, Hampshire
Notes: Thanks for alerting shortwave listeners to the British Antarctic Survey broadcast. It felt very poignant listening to a broadcast aimed at such a small number of people, with the voices of their loved ones being launched around the world.

I was able to record the broadcast from only 100 miles away from the Woofferton transmitter, so needless to say the quality and strength was very good. I imagine hearing that broadcast buried in the noise from far away with those happy birthday songs and best wishes must have been very emotional for its intended audience.

I enclose a short segment from my 30 minute recording, plus a photo (above) taken the next day of my set up (it was dark at the time of the recording).

My recording location was Basingstoke, Hampshire in the UK – locator IO91LH 20HH

[Note that Mark also recorded the full 30 minute broadcast which you can download by clicking here.]


SWL: Dean Allison

Notes: I have attached an audio file of the BBC transmission to Antarctica. My location is Bedlington, Northumberland, England, about 100 feet above sea level, using a Kenwood R5000 receiver and a 30 feet longwire antenna about 12 feet off the ground. This was the 5985 kHz transmission.

SWL: Jerry Rhys
Location: Surrey, England
Notes: Attached are two recordings of today’s BBC Antarctic Broadcast made between
2130 and 2150z. The first recording was made using AM mode with 8 kHz bandwidth on 5985 then 7360, followed by 6035. The second recording was made using SAM mode with 10 kHz bandwidth on 7360, 6035, and 5985.

The best signal was on 5985, 7360 was weak but readable, on 6035 I could detect a carrier and occasional modulation – on this frequency there was also interference from a digital transmission on 6037. Nothing heard on 9720.

I was using a RF Space SDR-IQ Receiver, and a Wellbrook ALA1530S Loop
Antenna installed in my loft. Many thanks for the SWLing Post, always an enjoyable read!

Notes:  Just thought I would let you know how I got on with the BBC WS broadcast to Antarctica. I used my Icom IC-R75 receiver and a Wellbrook ALA1530 inside the house. 5985 kHz was very strong with me here on the east coast of the UK (NVIS propagation?). Nothing heard on 6035 or 9720 but a weak signal on 7360. Attached (above) is a photograph of my listening post. This is a link to a YouTube video of the start of the broadcast. My very best regards and thank you for your excellent website.

Notes: Here is my attempt last night with SDR screenshot attached, Elad FDM-S1 with homebrew mini Mag Loop (<250mm dia) sitting on my bookcase. No doubt there will be better signals/recordings than mine as the signal was really strong from WOF and considering my setup is 100% indoors, it came out ok. External antennas don’t last here as I am by the sea and regular 100mph+ storms in the winter is too much hassle.

Notes: Here is my YouTube video. I’m using both the Sangean and Hammarlund receivers to hunt down the BBC Midwinter Antarctic Broadcast. Probably a somewhat different result than on most of the videos, but probably typical of West Coast propagation at these frequencies and times.


SWL: Nace Magner
Location: Bowling Green, Kentucky
Notes:  Please find attached a video of my reception of the BBC broadcast. Unfortunately, a thunderstorm passed through about 10 minutes prior to the video and the audio is dominated by lightning-related crashes. However, the BBC signal can be heard periodically. My location was on a university campus in Bowling Green, Kentucky, which is about 50 miles north of Nashville, Tennessee. I received the signal using a Tecsun PL-660 and its whip antenna. I enjoy the SWLing site. Best regards, Nace Magner (KW4LY)
