suburban DXing | The SWLing Post

Hi,

I would like to ask a few questions about what would be a good set up for my situation.

I am in a 2 storey property, which is not owned by me (renting via community/public housing), located in a large city in Australia. I currently have an SDRPlay RSP2, along with standalone AM/FM tuners – Sony XDR-F1HD and Onkyo T4970. The computer and all radios are upstairs at the back in a room that is not attached.

Given renting would limit what I can do, what would be best for me to get. For MW and SW frequencies, I am trying to decide between the MLA30+ or the AOR LA400. For above 30MHz (6m, 2m, broadcast FM etc) I am deciding between the AOR SA7000 or a Discone.

I have been told that putting antennas in the roof space is not recommended. Would they work fine in the room near a window? I should mention, I do have a 50ft end fed longwire with 9:1 balun, that has been in storage and never used.

I am also looking at upgrading my receiver. Trying to choose between the WinRadio WR-G305e or the Icom IC-R8600 (would also get the RS-R8600 CD software for computer controlling the receiver). How do the specs compare between these two?

Thanks for your time, and hope that wasn’t too many questions.

Regards,

Jamie

Thank you for your inquiry, Jamie, and I hope you don’t mind, but I’m sharing this message as a post as we have readers who are in the same type of living situation and listening environment. In addition, I believe owners of the gear you’ve mentioned might be able to offer some helpful advice!

I can tell you that you’re correct: in general, antennas want to be near windows or, better yet, outdoors. Even placing an antenna on a balcony can make a big difference in terms of lowering the noise floor. This is less an issue with VHF/UHF, but those antennas also benefit from being outside since there’ll be less attenuation from obstructions.

For HF, I would personally suggest you check out the MLA-30 loop first since it’s such a modest investment and is fairly flexible in terms of how you can configure it. I’m sure our regular contributor, Grayhat, will have some helpful advice as he’s a bit of an expert with urban HF antennas.

Also, the IC-R8600 is a brilliant wideband receiver. Depending on what you wish to have for frequency coverage, I would also suggest you check out the Icom IC-705 transceiver (noting that its RX coverage is not as comprehensive as that of the IC-R-8600).

Post readers: Please feel free to comment with some suggestions for Jamie, especially if you have experience with urban radio listening.

Hi there, the garden at my house is pretty small and as a consequence, I am very limited in terms of what antennas I can usefully employ. You can’t position anything further than about 10 metres from the brickwork and to compound this, we are surrounded on all sides by neighbours in close proximity. All very nice people, but all very noisy – electrically speaking lol. I simply can’t get far enough away from these sources of electrical noise to achieve excellent SNR.

The solution to my problem was ultimately a Wellbrook ALA1530 magnetic loop, but prior to that I used an end-fed random wire, the performance of which deteriorated as the months went by as the ubiquitous blanked of local QRM continued to increase. Eventually, I was forced outdoors, well away from my town – effectively catalysing my forays into the Oxfordshire countryside on DXpeditions. That first experience of listening to the radio on shortwave, in the absence of any QRM was enlightening to say the least and of course, subsequently, DXpeditions have become a mainstay of my listening activities. However, despite enjoying some great DX successes out in the woods, one has to be realistic about how often it’s possible to leave the house just to listen to the radio. This led me to the purchase of the Wellbrook ALA1530 magnetic loop. It proved to be a triumph of electrical noise mitigation and an absolute necessity in copying transatlantic medium wave signals in such a noisy and compact space. A total game-changer. The brilliant performance of the Wellbrook eventually led to me purchase a second, cheaper active antenna; the E-field Bonito Boni Whip and in turn, that purchase led me to the MegActive MA305, kindly supplied by Bonito themselves for objective testing.

Have DXing kit, will travel…everything you need in a small flight case…

You might remember my initial tests at home confirmed, as expected, that E-field antennas don’t work well in electrically noisy environments (except at LW frequencies in my experience) but outdoors, away from noise, they are superb. I have a number of reception videos on my YouTube channel – Oxford Shortwave Log which clearly demonstrate identical performance of the Bonito MegActive MA305 antenna and Wellbrook ALA1530 magnetic loop out in the woods. So, what if you’ve got a large garden in a suburban area that allows you to be just far enough from sources of electrical noise…how much of a difference does it make to the noise floor of your receiving equipment? Can E-field antennas such at the Bonito MegActive MA305 do the job? Furthermore, how well does a random wire work in a larger garden?

My MegActive MA305 antenna system for mobile DXing…and another use for a washing line…

I was fortunate enough to know someone who owns a house with a large garden, quite close to my QTH (a 10 minute walk) and who was more than willing to let me set up my DXing equipment and sit around until the early hours of the morning, listening to and recording various signals on my Eton Satellit. In preparation, I set up the Bonito MegActive MA305 antenna and hung the radiating element on the washing line – sounds ridiculous but actually worked very well, placing it about 2.5 metres above the ground. I also set up a 40 metre longwire, which at its closest point, was still approximately 25 metres from the house, and 30 metres from the neighbours. This post will focus on the performance of the MA305; a subsequent post will detail the performance of the longwire.

The large garden I ‘borrowed’ for my DXing session with the Bonito MegActive MA305 antenna

Suffice to say, the MegActive MA305 performed admirably during my first listening session. In the middle of the afternoon I copied a very strong signal from The Voice of Korea around 15:44 hrs UTC on the 25 metre broadcast band, followed at 17:10 hrs UTC with a superb signal from The Voice of the Broad Masses 2, Eritrea, on the 40 metre ham band. Later on in the evening I copied Radio Mail with excellent modulation, CHU Canada with voice announcements (almost impossible at home), Myanmar Radio with an untypically strong signal and XEPPM Radio Educación from Mexico City with a signal I would normally expect on a DXpedition-proper with a large antenna.

My conclusions to this experiment are simply that E-field antennas can work in a suburban environment, if you are able to site them far enough away from adjacent sources of electrical noise. I don’t have empirical data on this, however, I can confirm that 10 metres proximity is too close at my QTH and 30 metres is sufficiently far away at this test location. One has to assume the houses nearby are similarly equipped to mine with electrical appliances that generate electrical noise. Thus, if you’re interested in a very well-priced, compact antenna and you live in an urban or suburban environment with access to a large garden/ outdoor space, an E-field Boni Whip or MegActive MA305 might well be suitable – and you’ll have a superb portable antenna for those listening sessions away from home!

Finally, I should mention the Eton Satellit. Much-maligned in certain quarters when it was first introduced into the market, it continues to demonstrate superb DXing credentials. I won’t forget some words of wisdom from a friend of mine and fellow DXer, with more than 3 decades of experience in listening to the bands on HF. He told me that Judging from his own experience with some of the original Grundig Satellit models of the 1980s and early 90s (namely the 400, 500 and 700) he was quite sure that the Eton Satellit is a considerably better DX performer than those vintage sets, that offered great sound for casual listening to international broadcasters, but didn’t perform too convincingly on weak DX signals. The Eton Satellit has been a revelation and I’m pleased to have played a small part in turning around the rather widely held view that it was less than worthy of the Satellit branding.

Fresh out of the box, the Eton Satellit has surpassed all my expectations…
