Hi there, my clearest reception of Angola to date, using a 50 metre longwire and another vindication of this excellent portable receiver. Rádio Nacional de Angola can be a very challenging DX target, particularly at home, where more often than not, modulation is very low and thus discernible audio difficult to capture. Here on a DXpedition, the Eton really pulls in a strong signal with very clear audio and again, I wasn't anticipating such strong performance. Recorded at the woods in Oxford UK on 22/01/17 at 19:17 hrs UTC using a 50 metre longwire. 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 #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.

Bonito Boni whip versus Wellbrook ALA1530: RÚV Iceland, LW Test #2 winner: Wellbrook
Another disaster for the Bonito Boni whip. Here RÚV Iceland can be clearly heard with very decent signals on 189 kHz and 207 kHz using the Wellbrook ALA1530. Switching over to the Boni whip results in no discernible audio with the disappearance of both Icelandic signals under a blanket of noise. I've never seen anything like it and I actually reverted back to the Wellbrook to confirm this was as a result of the Boni whip antenna. Terrible peformance, even worse than the previous example with Medi 1. Hopefully, the situation will improve on MW and SW. Thanks for watching.
