The Elad FDM-DUO (Photo: Dennis Walter)
Many thanks to Dennis Walter who shares the photo above from the 2017 Ham Radio Friedrichshafen convention.
I’ve always thought the FDM-DUO was a cool transceiver, but I must admit it looks even better in camouflage.
I did warn our buddy Clint (Oxford Shortwave) that he should stick with his stock black FDM-DUO. You see, he takes his FDM-DUO to the field…literally. Can you imagine how he’d feel losing his top-notch camouflaged DX rig in the rough? 🙂
Hi there, I’ve been rather preoccupied of late, initially with the brilliant Tecsun PL-310ET and latterly with the even more brilliant Eton Satellit. However, in the background (as always), I’ve been trying to catch transatlantic medium wave DX. My listening schedule is broadly based on shortwave DXing during daylight hours – when I’m not at work of course, typically a Friday afternoon or at weekends – and always with a portable. Evenings usually start off with a tune around the tropical bands, followed by setting up the Elad FDM DUO to run some medium wave spectrum recordings overnight. In the past few days though, my daylight DXing has been bolstered by my NooElec RTL-SDR and ‘Ham it up’ upconverter. I bought the device over a year ago and after some initial exceitement, it quickly became quite obvious that I needed a reciever with a bit more ‘oomph’! However, it’s actually proving very useful to view signals on a spectrum, even when I’m conducting most or all of my listening on a different (i.e. higher performing) receiver. Ultimately, the RTL-SDR is always going to be a compromise, with relatively limited sensitivity, but because by it’s very nature it has excellent selectivity, overall it’s a reasonable performer. My particular RTL-SDR performs quite well if a decent antenna is employed with it, such as a longwire or the Wellbrook ALA1530 active loop.
Anyway, back to the medium wave DX. In the past month or two, I’ve copied a number of stations from North America, with really nice signals, including WRCR Rampano – New York, WFED Federal News Radio – Washington DC, WENE – Endicott and WUNR – Brookline from Newton, Mass. I’ve also recorded a lovely interval signal from RAI Radio 1, Milano and further European signals from Magyar Radio, Budapest and Radio Slovenija 1, from Ljubljana. During the past 18 months or so of DXing, I have been mostly ignoring signals coming into Oxford from the continent. However, that changed a little after I stumbled across the RAI Radio 1 interval signal, which complete with the rather rousing Italian National Anthem, inspired me to dig out some more European DX. I’m actually finding European DX quite rewarding, particularly because it feels new again – not surprising since I haven’t listened to Europeans on medium wave for any length of time since the 1980s. I hope you enjoy the reception videos – embedded video and text links follow below and I wish you all the very best DX.

Someone recently described my shack in Oxford as ‘an impressive mess’…. and that really is just about the most positive comment I’ve ever received regarding my listening post! So, my apologies for displaying the mess in public, but in response to having been asked many times by subscribers to Oxford Shortwave Log to ‘share my shack’, here it is, well most of it at least, in all it’s unadulterated glory.
The primary reason however for this post is to share my most recent transatlantic medium wave catches using the brilliant Elad FDM DUO and Wellbrook ALA1530 magnetic loop antenna. This excellent combination continues to pull in really nice DX, although not so much very recently as propagation has been fairly rubbish. However, since early to mid December, the dynamic duo have managed to pull in a number of transatlantic medium wave signals, including Radio Rebelde, Cuba on (670 and 710 kHz), KVNS Texas, CHIN Radio, Toronto, WFED Washington DC, WWNN Health and Wealth Radio, Pompano Beach, Florida, and huge signals from WMEX Boston and WWKB Buffalo, New York. Embedded reception videos and text links follow below and in the mean time, I wish you all great DX!

Hi there, I thought I’d share with you, three recent catches from Canada that I had not previously heard here in Oxford, UK, over the past 18 months of DXing. The first is VOWR, a religous station in Saint John’s, Newfoundland and Labrador. At the time of reception their TX power was 2.5 kW, thus a really pleasing catch. 800 kHz is such a difficult channel to DX in Europe due to heavy adjacent channel QRM, but the brilliant selectivity of the Elad FDM DUO operating via the FDM-SW2 software performed really well, producing mostlyy intelligble audio on LSB with an audio bandwidth filter of 2.1 kHz. Below is an embedded video and text link.
MW DX with 200 m Beverage: VOWR 800 kHz, St. John’s, N&L, first reception, with ID
The next reception video is CHHA ‘Voces Latinas’ from Toronto on 1600 kHz. This was the biggest surprise because this channel at the start of the X-band is dominated by The Caribbean Beacon, Anguilla. In fact, I would go so far as to say I’ve never heard anything else but Anguilla on 1600 kHz. The only difference in this reception is that it occurred relatively late in the morning for me – around 7:45 am. To catch CHHA for the first time, with a very clear ID was great, I hope to hear them again soon. Below is an embedded video and text link.
Finally, a reception video of CBC Radio 1, transmitting on 1140 kHz. CBC are very often herad at my shack in Oxford, in fact, I see at least one carrier, usually with audio most evenings/mornings and often multiple signals are present across 600, 750 and 1400 KHz. However, their transmission from Sydney, Nova Scotia had never been copied previously and so this was a pleasing catch. Below is an embedded video and text link.
Thanks for reading/watching/listening and I wish you all great DX!

Tour of a medium wave spectrum with over 20 transatlantic signals
Hi there, I thought some of the readers of SWLing Post might be interested in a review of a MW spectrum with multiple transatlantic signals – all with audio. This is one of the recordings I took with the 200 metre Beverage antenna and although I haven’t properly counted, I believe it generated about 50 catches that were either personal firsts or best-ever receptions. You will note that this video is nearly 20 minutes long, whilst the recording is only just over 5 minutes, thus to capture the signals listed below and demonstrate audio to you, it was necessary to effectively ‘rewind’ a few times. I haven’t annotated the video, however, the stations I’ve paused on to demonstrate audio are listed below. There are actually more catches in this spectrum, but hopefully the video will give you a good idea of propagation on the morning of 10/10/16 and the effectiveness of the Beverage/Elad FDM DUO combination. Also note, I didn’t have time to fully optimise the demodulation settings, so for example, I haven’t used AM SYNC in this demonstration. Individual videos of all catches, with optimised settings appear on my YouTube channel Oxford Shortwave Log. I hope you enjoy it! Recorded in Oxford UK on 10/10/16 at 02:00 hrs UTC. Thanks for watching and I wish you all great DX!

Hi there, here is the second set of reception videos for my transatlantic MW DX catches using the 200 metre Beverage antenna. Most of the signals originate from the United States and Canada, however, there is also a catch from Mexico – XERF La Ponderosa – which is a personal first and another from Bogotá, Colombia – Verdad Radio. I hope you enjoy them. Please do not hesitate to contact me if you would like further details regarding the Beverage design and/or construction. in the meantime, thank you for watching/listening and I wish you all great DX!

Hi there, a few weeks ago I posted a couple of medium wave DX catches with the Elad FDM DUO and newly constructed 200 metre Beverage antenna. Since then (and following my trip to Brazil) I have uploaded several more catches, some of which I would like to share with you. It has become evident that the Beverage’s low-gain but high SNR properties resulted in a huge increase in the sensitivity of my entire set-up and as a result. I have achieved numerous personal firsts on the medium wave band, coupled with many other signals that I can only describe ‘best-ever reception’. If nothing else, this endevour has underlined the importance of utillising the best antenna possible for your particular circumstances. We’ve all read at some point, how, in many respects, the antenna is more important than the receiver – and these catches demonstrate how absolutely true that statement is. All of the reception videos were captured using the Elad FDM DUO running on a home-brew battery-pack and connected to the Beverage via a 50 Ohm input transformer.
Below is the first set of reception videos, most of which are signals from East Coast of the United States. However, there is also an absolutely booming signal from WGIT Puerto Rico into my QTH in Oxford UK. Part 2 will follow almost immediately, but in the mean time thanks for watching/listening and I wish you all great DX!
