BBC News and CBS News announced today a new editorial and newsgathering relationship that will significantly enhance the global reporting capabilities of both organisations. The announcement was made by BBC Director of News and Current Affairs James Harding and CBS News President David Rhodes.

This new deal allows both organisations to share video, editorial content, and additional newsgathering resources in New York, London, Washington and around the world. The relationship between BBC News and CBS News will also allow for efficient planning of newsgathering resources to increase the content of each broadcaster’s coverage of world events.

James Harding, BBC Director of News and Current Affairs, says: “There’s never been a more important time for smart, courageous coverage of what’s happening in the world.

“This new partnership between the BBC and CBS News is designed to bring our audiences – wherever you live, whatever your point of view – news that is reliable, original and illuminating. Our ambition is to deliver the best in international reporting on television. We’re really looking forward to working together.”

David Rhodes, CBS News President, says: “CBS News is completely committed to original reporting around the world – a commitment clearly shared by the BBC.

“There’s no better partner to strengthen and extend our global coverage than BBC News. I look forward to working with James Harding as we increase the capabilities of both organisations.”

Sharing of content between BBC News and CBS News will begin immediately. Additional newsgathering components will be rolled out in the coming months.

The partnership builds on a relationship that dates back to the early days of television and radio news. Legendary journalist Edward R. Murrow delivered many of his famed reports from Studio B4 at BBC’s London headquarters. Murrow discussed his fondness for his work at the BBC’s studio B4, including a microphone he kept in New York with the BBC logo he used covering World War II.

This new partnership replaces the BBC’s current arrangement with ABC News.

James Harding says: “Our relationship with ABC has been long and fruitful. We have worked side by side on some of the most significant stories of our time on both sides of the Atlantic, from the attack on the Twin Towers to the wedding of the Duke and Duchess of Cambridge. We wish ABC well and would like to thank them for many years of hard work and expertise.”

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who writes

Have a few IC-R8600 “first observations” posted on the test sample we now have here.

It looks much better in person than in the photos (very nice).

It is also a bit smaller than the IC-7300.

Thanks, Dave!

I’ll follow Dave’s updates for sure as he’s a thorough and top-notch reviewer.

To give you an idea of what Dave’s evaluated so far, check out some of his initial impressions:

A few “first” IC-R8600 observations (latest 1.10 firmware) :

  • General size is slightly smaller than the IC-7300 SDR HF Transceiver.
  • With the IC-R8600 having a near 2 AMP current draw, does make for very warm operation after a few hours on (that is over double current requirement of what the IC-7300 uses in receive.) It does NOT make use of any cooling fans…whew good news here ! The receiver requires an external power supply, and I REQUIRE my regulated linear power supplies NOT to run HOT with any continuous operation (I would never use a noisy switching supply with it , but that’s my choice). I say the minimum size to use is the Astron RS-12A. While this may seem overkill, we tried a smaller RS-7A and after being on for 2 hours it’s lone pass transistor was too hot to touch which is totally unacceptable to N9EWO’s standards. The RS-12A has 2 pass transistors and a larger heatsink (and thankfully still no fan to create room noise). We have NOT tested a RS-12A with the IC-R8600 to verify this, but should be the one to try (I say don’t go with a lower current model) ???
  • S-AM modes (AM Synchronous Detector) sadly works the same as in the IC-R9500. In other words, it does NOT help with AM mode fading distortion (adjacent interference help only). So another Icom receiver with very poor “Sync” performance. We can HOPE for improvement on this with later firmware update, but I would not hold my breath ?? Yeah, one can use manual ECSS (zero beat in SSB modes) which does excellent, but SSB modes have limited top bandwidth of 3.6 KHz as all Icom’s do.
  • It’s top mounted Internal speaker is surprisingly good for it’s size. Tone control has much larger “Bass” range over the IC-7300 (excellent). Super clean audio as with the IC-7300. Connected to a classic Realistic “Minimius 77” 2 way speaker sounds stunning.
  • Tuning knob is of a “clicky” type (detents) out of the box. Good news , there is to way select a “smooth” feeling knob by moving the 3 position slider adjustment on the bottom of the knob (it’s not so easy to do however). So it goes from left to right : smooth loose – smooth tight – clicky. It has some rotational play in the “clicky” mode (but so does the IC-R9500’s knob in “clicky ” mode), but overall it feels good and this knob scheme was well done.
  • FMBC reception has a strange ACG pumping trait. Of course on the FMW mode the AGC and decay rate are not adjustable.
  • Uses no (or fewer) relays with it’s front end filters at least on SW. The “click and clack” when tuning around with the IC-7300 in the SWBC bands does not exist with the IC-R8600 (uses didoes ??). When we can locate a schematic will tell the whole story here (NOTE : No schematics are included with the set).

I’m really curious to see how the IC-R8600 stacks up to the IC-7300 on the HF bands. Looking forward to your updates, Dave!

Icom IC-R8600 pricing and availability

The new Icom IC-8600 at the 2017 Hamvention

At the 2017 Hamvention, I spent a little time checking out Icom’s latest wideband communications receiver: the IC-R8600. Check out the photos above and below.

The IC-8600 Back Panel

I spoke with Icom North America at Hamvention–the representative told me the MSRP of the IC-R8600 would be about $2,999 US, but that retail pricing would be lower.

Universal Radio now has the IC-R8600 in stock with a retail price of $2599 US. HRO has the IC-R8600 in stock as well and selling for the same price.

No doubt, at this price point, the ‘8600 is not ideally placed to compete with other receivers and SDRs. I do, however, believe this product will do well with government sales. No doubt, it should deliver benchmark performance (at least one would expect benchmark). Icom has offered to send me an IC-R8600 on loan for a review–it is tempting to see how it might stack up against some of my SDR arsenal.

I’m very curious Post readers: assuming benchmark performance, how many of you would purchase the IC-R8600 at $2,599 US? Please comment!

Ham Radio: 2017 Eclipse Experiment

Many thanks to SWLing Post contributor, Colin Newell, who shares a fascinating 2017 eclipse experiment outlined on the website HamSCI.

Here’s the summary of the experiment:

On 21 August 2017, a total solar eclipse will traverse the continental United States from Oregon to South Carolina in a period of just over 90 minutes.

Previous research shows that the shadow of the eclipse will impact the ionospheric state, but has not adequately characterized or explained the temporal and spatial extent of the resulting ionospheric effects.

HamSCI is inviting the amateur radio community to contribute to a large scale experiment by participating in an Eclipse QSO party and further developing automatic observation networks such as the Reverse Beacon Network.

Data resulting from these activities will be combined with observations from existing ionospheric monitoring networks in an effort to characterize and understand the ionospheric temporal and spatial effects caused by a total solar eclipse.

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following video from CBS Sunday Morning and notes:

For those who may have missed this recent CBS Sunday Morning piece, which tells the story of a guy who, inspired by BBC broadcasts of Wimbledon, built his own top-level court in Iowa. It’s not often that shortwave gets such national exposure:

https://www.youtube.com/watch?v=UF20Cem5ado

(Via CBS Sunday Morning on YouTube)

“If you build it, they will come.” In the case of one tennis-obsessed fan who built a replica of Wimbledon’s center court on his Iowa farm, people have come from around the world to his All-Iowa Lawn Tennis Club, to play on his court of dreams. Steve Hartman reports.

This absolutely made my day, Dan!  Thank you for sharing.
