Trying to copy Radio Afghanistan on 6100 kHz
I've been trying to record Radio Afghanistan on 6100 kHz this afternoon with the Eton Satellit and Bonito Boni whip, but with no success. They've been copied by several DXing fellows on YouTube recently, so try to listen out for them. Severe adjacent channel QRM from China makes the English programme difficult to receive with any discernible audio.

240 metre barbed wire fence versus Boni whip: Zambia NBC Radio 1, 5915 kHz..the whip wins again!
Hi there, another comparison of the Bonito Boni whip and barbed wire fence and again, the whip does the business. I had serious concerns initially because it's performance at home in the 'electrosmog' was (understandably) terrible, worse than I had imagined. However, out in the field, in a quiet environment as my good friend and fellow whip user Giuseppe points out, it's a brilliantly performing, ultra compact antenna. Perfect for DXpeditions. Here the signal from Lusaka is so much clearer and stronger with the Boni whip, on what I would consider a properly difficult signal to hear well! Recorded in Oxford UK using a Sony ICF-SW55 receiver on 14/01/17 at 17:19 hrs UTC. Thanks for watching.
240 metre barbed wire fence vs Boni whip: Voice of Africa 9505 kHz, Sudan..the whip wins yet again!
Hi there, the Boni whip does it again, delivering a stronger signal than the barbed wire fence with this signal from Sudan. My £100 investment is starting to look like a good deal now! Recorded in Oxford UK using a Sony ICF-SW55 receiver on 14/01/17 at 16:44 hrs UTC. Thanks for watching.

240 metre barbed wire fence versus Boni whip : AIR National Channel 9380 kHz..the whip wins again!
Hi there, the whip trounces the barbed wire fence again, this time the target is the signal from All India Radio National Channel on 9380 kHz (TX Aligarh, 250 KW). Very nice to see the whip coming into it's own on a DXpedition! Recorded in Oxford UK on 14/01/17 at 16:39 hrs UTC using a Sony ICF-SW55 recevier. More videos in this series to come. Thanks for watching.
Bonito Boni whip versus 240 metre barbed wire fence: Voice of Indonesia 9525 kHz
Hi there, this is the first in a series of tests comparing the effectiveness of the 240 metre barbed wire fence as an antenna, to the very compact Bonito Boni whip. Whilst the fence delivers some very respectable DX with the Tecsun PL-310ET, in this reception video there is only one winner - the Boni whip. Great to finally demonstrate excellent performance of the whip on a DXpedition and for me personally, quite surprising as to how much stronger the signal from Indonesia was on the whip. Recorded in Oxford UK on 14/01/17 at 16:28 hrs UTC using a Sony ICF-SW55 recevier. More videos in this series to come. Thanks for watching.
Ready to start testing the Bonito Boni whip out in the field
Hi there, a short video to share my completed set up of the Boni whip out in the field. Sony ICF-SW55 clipped to the barbed wire fence. Reception videos to follow. Thanks for watching.

Setting up to compare the Bonito Boni whip performance to a 240 metre barbed wire fence
Hi there, I thought this would be an interesting experiment. Having established the effectiveness of the whip against the Wellbrook ALA1530 active loop and a 30 metre longwire in an urban environment, I turned my thoughts to how it would perform in a quiet location, up against one of my established ad-hoc antennas! A further test in the woods will follow, but for now, here is my DXing set up for comparing the whip to the barbed wire fence!. The results which are to follow, are quite surprising. Thanks for watching.
Urban DX antenna test #5: Comparing 30 metre longwire to Boni whip on LW
Hi there, here is the fifth and final video in this series comparing the Bonito Boni whip to a 30 metre longwire in an urban environment. This time the target signal is Polski Radio on 225 kHz longwave and finally the Boni whip produces clearer audio than the longwire. Despite a significant increase in noise floor, the SNR appears to improve a little. The Wellbrook reception at the end of the video is a final calibration as to what is possible with an H field antenna in a noisy urban environment. Thanks for watching.

Urban DX antenna test #4: Comparing 30 metre longwire to Boni whip on MW
Hi there, here is a comparison of the longwire and Boni whip on medium wave. Watch how the signal from CFRB Newstalk 1010 Toronto 1010 kHz is buried under noise with both, until it miraculously appears at the end of the video when the Wellbrook is connected. What can you say? In a QRM-laden environment, neither a longwire or Boni whip is going to deliver serious DX. The H field Wellbrook, however, does the business. One more video in this series to come, with an example on LW, where the situation is a little different, then on to a comparison in the field between the whip and barbed wire fence...also interesting results! Thanks for watching.

Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: R. Tupi/Super R. Deus e Amor, 11765 kHz,Brazil
According to online sources, this station broadcasts with a TX power of 10 kW, however, according to the WRTH 2017, the TX power is 20 kW, which I might be more inclined to believe. Either way, a nice catch on these portables. The performances of the Sonys are similar again, not sure which I prefer. The Tecsun struggles until the two narrowest filters are selected and then produces audio that fades in and out. Not bad at all for a sub £40 radio! Recorded in Oxford UK on 29/12/16 at 20:53 hrs UTC using an Wellbrook ALA1530 active loop antenna. Thanks for watching.

Urban DX antenna test #3: Comparing 30 metre longwire to Boni whip
Hi there, the third reception video in this series of tests, comparing the Bonito Boni whip with a 30 metre longwire in an urban environment and then, as usual, a check on how the signal is heard with the Wellbrook ALA1530. In this example of the signal from Myanmar Radio 5985 kHz, there is no audio with either the longwire or Boni whip, only the ALA1530 manages to resolve some audio from their weak modulation. A LW and MW example to come, where, in one instance, the Boni whip prevails against the longwire. Conclusion: on SW, there is no advantage to the whip over a longwire, but no disadvantage either. Thanks for watching.
Urban DX antenna test #2: Comparing 30 metre longwire to Boni whip
Hi there, the second comparison video in this series, this time using the large signal from CRI on 6020 kHz. Again, there's little difference in SNR performance between the 30 metre longwire and Boni whip. More to come. Thanks for watching.

Urban DX antenna test #1: Comparing 30 metre longwire to Boni whip
Hi there, following my one-on-one tests of the Bonito Boni whip and Wellbrook ALA1530, it became very apparent quite quickly and perhaps not unexpectedly that the Bonito E field antenna couldn't get near the performance of the Wellbrook. That led me to plan another set of tests out at the 'DX' woods and check the performance delta in a very quiet environment. In the meantime, a number of friends and fellows expressed an interest in compariing the Boni whip to a cheap piece of wire, so here is the first of a series of reception videos doing just that, with a final check of the signal at the end using the Wellbrook. The signal is Radio Nacional Brazilia 6180 kHz and I think you'll agree there's no difference to the audio obtained with the longwire or whip, only the Wellbrook produces something half reasonable on what was a night of very poor reception conditions. Hope you enjoy it.
Medium wave DX: 1310 kHz - is this CIWW 1310 News, Ottawa, Ontario?
Hi there, this is presumed because no clear ID can be heard. Intially I thought this signal might be WLOB, but then I thought probably not and this was confirmed by Matthias as there is no mention of Fox News or their usual fanfare. With a TX power of 50 kW, CIWW is another likely candidate. If anyone can shed further light on this catch, I'd be very grateful. Recorded in Oxford UK, on 07/01/17 at 07:59 hrs using an Elad FDM DUO and Wellbrook loop (indoors). Thanks for watching.

Bonito Boni whip versus Wellbrook ALA1530 test #7 winner: Wellbrook (7 wins out of 7)
Hi there, this is the final test comparing these two antennas in my noise-laden shack, using the Afia Darfur signal on 9510 kHz, from Santa Maria di Galeria, Rome, Italy. Once again, reasonable reception on the Wellbrook with an audio bandwidth filter of 6.6 kHz and a signal pushing over S9. However, once the whip is connected, the noise floor increases by more than 10 Decibels and the signal almost dissapears under the blanket of amplified noise. So it's 7 wins out of 7 for the Wellbrook, but I'm not giving up. For the next test, I'm interested to see how the whip performs against a 30 metre piece of wire slung around the garden - a less than ideal arrangement I used for some time before I purchased the Wellbrook. Then finally I'm going to take them both out to the woods and run another comparison. I must reiterate that I really want the Boni whip to prove itself an excellent performer in a quiet environment, because that would give me an excellent, very portable antenna to use on DXpeditions. Thanks for watching.

Bonito Boni whip versus Wellbrook ALA1530: Test #6 winner: Wellbrook
Hi there, I've taken a different approach this time - by using what is probably the strongest signal on shortwave at my QTH - CRI on 6020 kHz. With an 18 kHz audio bandwidth filter, audio fideltiy on shortwave doesn't really get much better than this. As might reasonably be expected wiht a huge signal, the difference in the performance of the two antennas based on audio fidelity at least, is much less obvious, despite the signficant drop in SNR with the Boni whip. One more reception video to come, to conclude this first series of tests. Thanks for watching.
Bonito Boni whip versus Wellbrook ALA1530: Test #5 winner: Wellbrook
Hi there, here is test number 5 and the first with a signal on shortwave - Radio Habana, Cuba on 6060 kHz. I would describe the signal strength and audio fideltiy as about average with the Wellbrook ALA1530 active loop. However, switching over to the Bonito Boni whip results once again in a significant increase in the noise floor - just over 10 decibels this time, but that's still very significant and the resulting loss of signal modulation is clear to see and hear. I'm still hoping that a trip to the QRM free woods in Oxfordshire will result in a much reduced SNR performance delta between these two antennas. Thanks for watching.
Bonito Boni whip versus Wellbrook ALA1530: Test #4 winner: Wellbrook
Hi there, here is the next MW band comparison test for these two antennas - a signal from WMEX Boston Talk Radio on 1510 kHz. Sometimes this station can almost boom in over the Atlantic to my QTH in Oxford, UK. However, two nights ago, their signal could, at best, be described as quite weak, but with some discernible audio using the Elad FDM DUO and Wellbrook ALA1530. However, when switching over to the Boni whip, the signal was completely buried under amplified local noise, thus another disapointing result.
I still believe the delta in performance of these two antennas will be significantly less in a quiet location and to this end, I will be conducting another test at the woods in Oxfordshire. I want the Boni whip to succeed because a) I've spent over £100 on it and b) it would be great to have a very compact antenna that peformed as well as, or even nearly as well as the Wellbrook to use on DXpeditions. Three more test videos to come, all of which target shortwave signals.
Thanks for watching.
