Medium wave DX: WENE "Fox Sports AM 1430" Endicott, NY, first reception & clear ID
Hi there, I was pleased to catch WENE, Endicott, New York for the first time with an ok signal, despite serious adjacent channel QRM. Again, the Elad operating via the FDM-SW2 software demonstrates amazing selectivity via the almost innumerable filtering options. Recorded in Oxford UK on 09/12/16 at 03:59 hrs UTC using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna (indoors). Thanks for watching.
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 #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 #1 winner: Wellbrook
Hi there, here is a signal from Medi 1 on LW 171 kHz with nice audio on the Wellbrook ALA1530. Watch as the Wellbrook is unplugged from the Elad FDM DUO and the Boni whip connected (using the supplied radiating element). The noise floor jumps by around 20 decibels and the resulting audio is severely compromised. I read that the Boni whip is often very ineffective in buildings, so I put both antennas in the garden to give it the best chance of success. The problem is however, that my garden is often noisier that inside the house because our neighbours surround us quite closely on three sides. Anyway, test number 1 is a disaster for the Boni whip. Let's see what happens next. Thanks for watching.
