The Bonito Boni Whip goes from strength-to-strength: hardcore DXing in compact package

Hi there, subscribers to the Oxford Shortwave Log YouTube channel and regular readers of this excellent website will be aware that I have been using a Bonito Boni whip E-field wideband antenna for a couple of months now. You may have seen my previous post here, detailing some excellent initial DX results achieved with the Boni Whip. What makes this antenna so compelling for a DXer such as myself is simply that it’s so light and compact; I can literally take it anywhere. Currently it lives in a small flight case (see above & below) on the back seat of my car, with either my Sony ICF-SW55 or Eton Satellit, a home-brew battery pack (that literally cost pence) and some peripheral bits and pieces; spare batteries, cables etc. I think it’s probably already clear that if you consider the Boni Whip’s performance as a function of portability and price, it’s out there on its own – I’m not aware of another antenna that can match it. Of course, there are H-field antennas, such as the excellent Wellbrook active loops that will effectively reject QRM, if that’s an issue for the user, but at a significant cost delta.

 

Since my last posting, I have continued to use the Boni Whip regularly on my DXpeditions and upload the reception videos to my YouTube channel. I have been nothing but totally impressed with this antenna, to the point that I’ve actually been surprised by the signals I’ve caught and recorded with it. Recent catches include a number of low-power stations from Brazil, including Radio Bandeirantes – Sao Paolo, Radio Voz Missionaria – Camboriu (on the 49 and 31 metre broadcast bands) and Radio Aparecida. Some of these signals are incredibly difficult to hear in Europe at all, let alone well and yet the ultra-compact Boni-Whip running off AA batteries, coupled to the (equally brilliant) Eton Satellit managed it with aplomb. Other catches include Zambia NBC Radio 1 – Lusaka and a signal from Bangladesh Betar that sounded as if the transmitter was 5 miles down the road!

All-in-all, I’m extremely satisfied with the performance of the Bonito Boni Whip and highly recommend it to those DXers requiring a high-performance, compact antenna, for use at home in electrically quiet environments or on any DXpedition. You certainly won’t be disappointed.

Which is the best? Sony ICF-2001D/2010 or ICF-SW77? The halfway score

Hi there, here is a summary of the first half of tests comparing the Sony ICF-2001D against it’s replacement the ICF-SW77. Both receivers are widely acknowledged as being amongst the best shortwave portables ever made, but how close are they in performance? Is there a clear winner after the first 8 reception tests? I hope you enjoy the summary video. Links to the first half of reception tests follow again, below, whilst the second half will follow in a separate post. Thanks and good DX to all.

Radio Fana 6110 kHz Ethiopia; excellent SNR with Elad FDM DUO

FanazaThe Elad FDM DUO makes for a fantastic receiver, in both standalone mode and via the FDM-SW2 software. Thus far it has been demonstrating this by outperforming the Sony ICF-2001D in many of my reception tests using an experimental longwire antenna. Bear in mind that whilst this might not be such a surprise, the Elad without the FDM-SW2 software driving it has no SYNC, which is often invaluable for Tropical Band DXing. To make the point further, here is a wonderfully clear signal from Ethiopia, with, in my experience at least, exceptional signal-to-noise.

My 200 metre longwire is still very much a work in progress. I am in the process of building a termination resistance box, receiver-end termination suitable for high and low impedance inputs and earthing straps for metre-long copper pipes that will remain in-situ. When I have completed these tasks, I will record a video because I know some of you are interested in the details. For now though, it just remains an experiment – 200 metres of wire and very late nights/ early mornings!  Recorded at the ‘DX woods’ in Oxford UK at 03:23 hrs UTC on 31/07/16. Thanks for watching.

Turn your Elad FDM DUO into a portable receiver, with a 200 metre longwire

As some of the subscribers to Oxford Shortwave Log  will know, I’ve been talking about building a battery pack for my Elad FDM DUO to take it out on a DXpedition. Finally, I found the time to quickly do just that with some parts that cost less than £10 – as the video below demonstrates in more detail. The FDM DUO input voltage is stated as 13.8V and although 12V would probably have been sufficient, a couple of very cheap battery cases later, 9 x 1.5V ‘C’ cells and about 20 minutes of somewhat unpractised soldering did the trick. I have also put together a 200 metre longwire antenna, deployable from a large spool, with a termination connector to add resistor grounding for a Beverage Antenna configuration, should I wish to do so in the future.  I used two spools of 100 metre equipment cable, soldered together and protected with heat-shrink.

Regular viewers of my youtube channel will know that I spend much of my shortwave listening time out in an Oxfordshire wood where QRM is negligable and Tropical Band stations can be heard with, at times, unprecidented signal-to-noise. This is the first time I’ve used a longwire greater than 100 metres in length, however, to be resonant at two wavelengths for 90 metres and 3 wavelengths for 60 metres was the objective. I hope the already fine Tropical Band listening to be had out in the Oxfordshire countryside will improve further.

Wembley Stadium: A Superb DXing location

Oxford-Shortwave

Many thanks to SWLing Post contributor, Clint Gouveia, who writes:

As the designated driver, I found myself waiting for friends at the Beyonce concert at Wembley Stadium last Sunday [July 3rd], Not wishing to miss an opportunity and taking advantage of 8 stories of elevation (top floor of the car park!) I spent about 3 hours DXing with the legendary Panasonic RF-B65 and a Wellbrook ALA1530 active loop, running on my home-brew battery pack.

Rather counter-ituitively, I quickly discovered there was basically zero QRM and recorded wonderful signals from Zanzibar BC, Radio Bangladesh Betar and Radio Oromiya. Links to the reception videos on my youtube channel ‘Oxford Shortwave Log’ follow below. I thought readers of your excellent website/blog might be interested to learn that sometimes the most unlikely of places can provide just about optimum conditions for DX! There are more reception videos for this particular session to upload,including Radio Fana, Voice of Tigray Revolution and Radio CANDIP.

73!

Reception Videos

Video 1: Zanzibar BC 11735 kHz, best ever reception

Video 2: Bangladesh Betar 13580 kHz, wonderful reception

Video 3: Radio Oromiya 6030 kHz, Ethiopia, best reception to-date

Wow! What amazing reception, Clint!  I would have never guessed that a car park next to the largest stadium in the UK would offer up such excellent listening conditions. Honestly–that Bangladesh Betar broadcast sounds like a local station.

You also have a great receiver there in the Panasonic RF-B65. If memory serves, the RF-B65 is also a favorite of SWLing Post contributor/DXer, Dan Robinson.

Thanks again for sharing, Clint, and reminding us that DXing locations aren’t always remote and exotic.
