Using A Mixing Console in the Radio Shack

As a result of numerous responses to another video I posted on my YouTube channel a few weeks ago, I have now prepared a video that gives you a detailed look at using the Behringer Xenyx Q802 USB mixing console.

The unit is wired up to four receivers, then sent off to a pair of powered speakers. I cover how the mixer is connected to the radios and the speakers, explain the various controls available to the shortwave radio listener and amateur radio operator, the advantages of using this system in the radio shack, and offer a few tips when buying a mixing console such as this Behringer unit.

If you have a few receivers kicking around in your radio shack, this is one way to hook them all together and send their audio on to your favourite monitoring speakers. Thanks for taking the time to watch this little video. As always, comments and feedback are most welcome.

 

73 and good DX to you all,

Preparing for Your Next DXpedition – New Videos

Regular readers of the SWLing.com blog will be aware that I am passionate about going portable/mobile with my radio listening hobby. There’s just nothing like communing with both nature and a bunch of electrons whizzing along the wire!

As a follow-up to an article I wrote several years ago, I have now prepared two new YouTube videos entitled Preparing for Your Next DXpedition – Parts 1 and 2.  

Part 1 covers:

– why we should even think about bothering to go portable with the radio

– the goals to consider when undertaking a DXpedition

– planning your listening depending on the time of day and time of year

– the all important decisions regarding location


Part 2 discusses:

– choosing the right radio for portable operations

– your options for powering the radio

– the antennas you could consider including on the trip

– handy auxiliary equipment

– references and notes to take along with you

– the importance of operator comforts while away

– developing a checklist…..so that you don’t forget to take something important!

These videos will be of interest to shortwave radio listeners and new amateur radio operators. Hopefully, they may be able to assist you in further enjoying our great hobby. They are embedded in this blog post below. You can also view these and other videos on my YouTube channel at Rob Wagner’s YouTube Channel

 

As always, thanks for watching and your comments are always welcome. 73 and good DX to you all,

Ozy Radio Returns

The flea-powered Ozy Radio has begun testing on 5045 kHz in the 60-meter band. First noted here in Australia on August 28, the station has been missing for several years from its former 3210 kHz allocation. The location has been reported as Razorback, New South Wales, but I have not been able to confirm this yet. The transmitter power and the type of antenna are also unknown at this time. Observations by myself and other Australian listeners have noted the station operating between 0600 and past 1300 UTC.

The signal into Mount Evelyn, Victoria (at a guess, about 800 km from the reported transmitter site) is very strong – about 10 dB over S9! This is a much better signal than was ever heard on the old 3210 outlet. Whatever has been done at the station appears to be working very well! I believe there could be a very good chance that Ozy Radio will be heard internationally!

The current programming consists of test transmission announcements, relays of the Australian Independent News service, and continuous antique pop music from the 50s and 60s. Cheekily, the station is also using the Radio Australia interval signal, while the RA kookaburra also fires off every now and again throughout the broadcasts. I’m not sure how the ABC feels about that!!

Here is a short video I prepared of the test announcement and email address given out at 1356 UTC.

Good luck with hearing Ozy Radio!

UPDATE:  The current power output is 500w and the location is confirmed as Razorback, near Camden approx 45 km southwest of Sydney. Thanks to John Wright for the eQSL statement and information. John also reports that reception reports have been received from as far away as Germany.

Horizontal Loop Antenna Experiments

Man-made RF noise levels have increased dramatically at my place in the past six months. It has become much harder to hear weaker shortwave signals. Even the stronger stations are getting covered in all types of hash from all manner of electrical appliances.

So, I have been looking at ways to reduce the noise problem. I’m currently researching a few possible solutions, including trying a different antenna.

The HF horizontal loop has been around for many years now, but it’s a new antenna for me. I’ve never had a need to try one…..until now! There is some documentation out there praising this antenna’s low noise capabilities. So, it was time to find out for myself and start building an experimental version. So far, the results have been really quite pleasing!

I have prepared a YouTube video (below) in which I discuss the reasons for looking at this antenna, its design, and its installation. I also do some on-air comparisons of my experimental rectangular (!) version of the horizontal loop against my three regular double bazooka (coax) dipoles and the Par SWL End-Fed antenna.

Have you tried this antenna before? Your thoughts and feedback would be most appreciated.

73 and good DX to you all,

New Mediumwave Facility for Fiji

There’s an interesting YouTube documentary released by the Fiji Broadcasting Corporation on the refurbishment of both transmitters and antennas for the mediumwave outlets of 558 and 990 kHz. This was completed with the financial and technical assistance of the Japanese government. It will be very interesting for MW DXers to see how well the new facility will be heard beyond the Fijian borders.

 

There is also a somewhat less interesting YouTube video of the Fijian dictator Prime Minister Bainimarama at the official launch of the revitalized service, which can be found at https://youtu.be/kOza_Ov7f48

It was fascinating to hear Prime Minister Bainimarama talking about democratic freedoms in the broadcasting media….This from a man who for many years has done his level best to suppress and control the Fijian media on countless occasions!
