Transatlantic medium wave DX: 3 Canadian stations rarely heard in Oxford, UK

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!

Norway becomes first country to go “fully digital”

(Source: RadioInfo via Kris Partridge)

11th January 2017 is a historic day for the medium of radio.

Norway becomes the first country in the world to move towards fully digital radio transmissions. As a result of this, the national FM network will be switched off.

The FM networks will be switched off region by region, starting in Nordland 11th January. The event will take place in Bodø and the final switch-off will be done at 11.11 pm CET.

The heads of NRK radio and commercial radio will be in Bodø to represent the Norwegian radio industry. Also, head of BBC radio, Helen Boaden, and head of radio at EBU, Graham Dixon, will attend.

An international seminar for European broadcasters will be held the day before the historic move to FM switch-off and an international press-conference will be broadcast on radio.no at 2 pm CET.

The final program will be published nearer to the event.

Medium wave SDR spectrum with over 20 transatlantic signals: a quick tour

 

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!

Medium wave DX: Colombia, Peru, Ecuador and Venezuela heard in Oxford, UK

part-south-america

Hi there, I thought I would share a few recent medium wave DX catches from South America. In the past month or so, I’ve managed to record signals from Colombia, Peru, Venezuela and one that I’m particularly happy about – Ecuador, which is rarely reported in Europe. All catches were obtained with my usual indoor home set-up – the brilliant little Elad FDM DUO coupled to the equally brilliant Wellbrook ALA1530 active loop antenna. I have started to take the Elad on DXpeditions now, having constructed a battery pack for it, but the results I’m yielding outdoors are so far mainly with shortwave reception, where the improvement in SNR is quite obvious in the size of the carriers I’m observing and much improved modulation/ audio clarity on the Tropical Band. Hopefully in time, similar results will yield on medium wave. In the meantime, Im very happy with the indoor performance and these catches demonstrate that. There are many more reception videos on my YouTube channel Oxford Shortwave Log, including a large number of signals recorded from North America on medium wave. Direct links follow below and further down, embedded reception videos. Thanks very much for watching, listening and I will you all excellent DX.

AM radio proposal has Class A broadcasters upset

WHKY-AM-Radio-Tower(Source: Times Union)

When the sun goes down, AM radio signals travel much farther. You can listen to 50,000-watt stations such as WGY hundreds of miles away.

But that could soon change, if the Federal Communications Commission goes through with a plan to let more local stations broadcast through the evening hours and potentially makes changes in the daytime signal of WGY and other powerful stations.

The proposed change in protections to Class A stations such as WGY would ease restrictions on the smaller stations, which are now required to reduce power or change the direction they broadcast their signal so they don’t conflict with the more powerful Class A stations.

WGY has begun an online petition drive to oppose the changes.

Called “Save AM Radio,” the petition opposes reducing WGY’s so-called “protected service area.”

The changes, WGY says, “will make it very difficult for many of our listeners to receive our programming, especially at night and during morning and evening drive times.”

[…]The FCC, meanwhile, says the changes are being considered in an effort “to help revitalize the AM service.”

More local stations would give listeners a wider choice of programming, supporters of the change argue.

[…]WGY’s online petition is at http://www.wgy.com/features/save-am-radio-1919/
The FCC is accepting comments through March 21 and replies through April 18, at www.fcc/ecfs. Click on “submit a filing.” The proceeding number is 13-249.

I’m very curious what Post readers think about this proposal from the perspective of both access to regional information, as well as from MW DXing. Will this move crowd the AM broadcast band or give local stations a stronger voice?
