BBG’s Fiscal Year 2016 Congressional Budget Request

BBG-Budget-Request

Many thanks to SWLing Post contributor, Richard Langley, who shares a link to the Broadcasting Board of Governor’s Fiscal Year 2016 Congressional Budget Request.

I’ve read key portions of the request.

Regarding shortwave, the BBG are asking for budget reductions in almost all of the BBG shortwave broadcasting arms, with a few exceptions.   They acknowledge, in each case, that shortwave broadcasting is not as cost-effective as other means of distribution (including FM, Internet and satellite). The do acknowledge that shortwave broadcasting is still needed in some strategic markets. Here is, perhaps, the most telling quote I found:

“To serve audiences in less developed areas of the world, BBG must continue to broadcast via traditional technologies such as shortwave and maintain capability on these platforms by replacing antiquated equipment. But to stay relevant in competitive news markets and serve current and future audiences, BBG must invest in new cutting-edge technology. In areas where ownership and usage of shortwave radio has declined significantly, the Agency has evolved away from broadcasting in shortwave.”

A few specific highlights from the request:

4) ENHANCE HIGH FREQUENCY TRANSMISSION CAPABILITY ($2.8M)
BBG will continue the shortwave realignment project that began in FY 2014, which increases shortwave transmission capability at its Kuwait Transmitting Station. This enhancement provides improved coverage to underserved areas of the world and
reduces operating costs by decreasing reliance on external leases. All aspects of
this proposal focus on improving transmission capability, while continuing
to reach audiences in Africa, Afghanistan, Pakistan, Iran, Tibet and
Western China. The added capacity will support broadcasts for RFE/RL, RFA and
VOA.

At $2.00 per broadcast hour, Kuwait provides the highest return on investment in the BBG transmitting station portfolio. Thus, BBG began expansion of the facility in FY 2014 with
the construction of a new high frequency antenna and design of the transmitter building expansion. The proposed investment, extending through FY 2018, will bring the Kuwait
Transmitting Station up to the maximum capability allowed by the country agreement and will enable the Agency to decrease overall operating costs for the foreseeable future. When the realignment project is completed, the Kuwait station will have ten shortwave transmitters with associated antennas.[…]

Page 22:

Reduce Shortwave Costs [-$2.90M] The Office of Technology, Services, and Innovation (TSI) will eliminate less effective transmission frequencies and realign transmissions to end high cost leases. TSI will realize additional reductions to antiquated technologies by reducing transmissions to Afghanistan, Pakistan, Burma, and Kurdish-speaking regions and eliminating shortwave to Russia, the Caucasus, Belarus, Laos, Cambodia, Rwanda, and Burundi. Audiences in these countries access news and information on more efficient,[…]

STRATEGY BASED ON AUDIENCE
MEDIA HABITS
Using research on audience media habits, TSI will continue to move away from less effective legacy shortwave and medium wave transmissions toward other technologies, where appropriate, to reach larger and younger audiences. Where shortwave remains important, TSI is building a more cost-effective transmission infrastructure to support broadcast requirements. Of particular note are efforts at the Kuwait Transmitting Station. Because of the station’s strategic importance and low operating costs, TSI is installing a new shortwave antenna that is expected to be operational in FY 2015 and will expand the station’s transmitter building in FY 2016 to accommodate future transmitter build-outs.[…]

To serve audiences in less developed areas of the world, BBG must continue to broadcast via traditional technologies such as shortwave and maintain capability on these platforms by replacing antiquated equipment. But to stay relevant in competitive news markets and serve current and future audiences, BBG must invest in new cutting-edge technology. In areas where ownership and usage of shortwave radio has declined significantly, the Agency has evolved away from broadcasting in shortwave.
BBG has closed transmission stations, repurposed equipment and invested these savings in platforms that the audience has shifted to, primarily in digital media technology and other high-priority programming.

GODAR antennas

GodarAntennasMany thanks to SWLing Post contributor, Mario Filippi (N2HUN), who writes:

[Check out] this site I came by accidentally, small company, USA made antennas, most are OTA TV but he has a few shortwave antennas, quite reasonable. […] Also has old vintage pics. A little of this and that on the website, quite interesting company. He sells on Ebay too.

GODAR USA

Thanks for the tip, Mario. I love supporting mom-and-pop manufacturers like Godar. It appears–based on his eBay rating–that Michael Godar has very satisfied customers and produces quality antennas.

Thanks for the tip!

Let’s talk Raspberry Pi 3 radio projects…

RaspberryPi3-Box

I just received the recently released Raspberry Pi 3 that I ordered from MCM a couple weeks ago.

RaspberryPi3

Now I’m plotting a few potential radio projects!

Recommendations anyone?

I’d love some input from SWLing Post readers as I’d like to feature a few Raspberry Pi projects here (and I’d certainly welcome your guest posts!).

RTL-SDR

I’d love to run my RTL-SDR or (better yet)  SDRplay RSP with the Pi 3, but I’m sure there are a number of other projects I’ve never considered. I also have the original Raspberry Pi, but what I love about the Pi 3 is built-in wireless connectivity–of course, it’s faster than the original Pi, so I’m sure that’ll help with many radio applications.

Please comment with your suggestions and Raspberry Pi experience! I’m all ears!

Radio Prague: Underground agents and plots in the Cold War broadcasting war

HalliDial

Many thanks to several SWLing Post readers who shared the following story from Radio Prague:

Underground agents and plots in the Cold War broadcasting war

In this week’s Czech History we look at one aspect of the Cold War, the use of secret agents to spy on and disrupt the enemy’s propaganda services. In particular, we focus on the circus that surrounded the return of a Czechoslovak double agent Pavel Mina?ík 40 years ago in 1976 which was aimed at discrediting the US financed and Munich-based broadcaster Radio Free Europe.

Guest Post: Jerry’s Mediumwave DXing Powerhouse Mini FSL Antenna

Many thanks to SWLing Post contributor, Jerry Popiel, for the following guest post:


PowerhouseFSLAntenna-1

A MW DXing Powerhouse Mini FSL Antenna

by Jerry Popiel

In late February 2016 I completed construction of a modified version of Gary DeBock’s excellent 3 inch Mini FSL design (click here to view).

This new antenna is nothing short of a AM DXing powerhouse with unbelievable sensitivity for receiving stations across the entire AM Bandwidth both day and night. The tuning of stations is razor sharp and it has stunning nulling qualities. Consultation assistance was provided from DXing experts Steve Ratzlaff and Gary DeBock on the project.

Construction Details:

The Antenna was constructed using 9 – 100 mm Ferrite Bars wound on a 2.75 inch diameter x 4 inch styrofoam cake dummy form custom made by in Vancouver, B.C. Canada – ([email protected]) for $3.50 plus shipping.

The Coil wire consisted of 38 turns of high gain 660/46 Litz Wire. (Note: As can be seen 38 turns of the thicker Litz Wire left only 5/8” of room on each side of the Styrofoam Form to wire wrap the coil to the ruler frame. A longer Form ie 5” long would work much better for this build).

The insulation spacer used was 2 layers of 1/8 inch Aerotape self adhesive tape which also helped hold the 100 mm Ferrite Bars onto the Styrofoam Coil Form. Inductance measured 356 uH using a DM 4070 Meter which is well within the requirement of over 300 uH for AM Band Reception.

Because of the extra thickness of high gain 660/46 Litz Wire which is a bit too big to solder to the inside terminals of the Tecsun PL-380 Radio, a 2 Position Terminal Block was superglued to the outside of the Ruler Frame to act as an interface connection point.

Testing Results:

Both daytime and evening AM station captures have been spectacular. Stations as far away as KKOB / 770 kHz Alberquerque, New Mexico 1130 Miles from here in Winnipeg, Manitoba, Canada have been received. Country music station WSM / 650 kHz in Nashville, Tennessee 1082 miles distant is a daily evening pickup.

Two Stations Received At 600 kHz 90 Degrees apart at the same time:

The amazing Nulling and Razor Sharp Tuning quality of this FSL was demonstrated when 2 stations at 600 kHz were received at the same time by rotating the Radio with attached FSL 90 degrees. In the North / South direction Station KSJB / Jamestown, North Dakota (219 miles distant) was received with a strong signal strength of 50 / 23. Then by rotating the Radio 90 degrees to the East / West direction Saskatoon, Saskatchewan station CJWW (442 miles distance) was captured with a similar strong signal strength of 44 / 24.

All Indoor Reception – For Now!

Due to winter conditions here in Winnipeg, all of the amazing station reception captures in this report were done inside the House facing towards the South window. Fortunately the red ruler platform sides can he used as handles when pointing the radio in the direction of best reception. Exciting times are ahead to see how well this mini 3” FSL will perform outdoors for likely even better AM DXing.

Summarizing:

The design of this new FSL Antenna attached to the Tecsun PL-380 Ultralite radio by Gary DeBock is a major breakthrough in AM DXing since the Radio is attached to the FSL. This new FSL Antenna needs to be constructed to be really appreciated. The application described here requires a bit more skill to construct and is also heavier than the original construction – but at least it is portable. For beginners Gary’s original 3” FSL Heathkit Design is highly recommended and can be reviewed in his You Tube Video posted at: https://www.youtube.com/watch?v=VY9u8MReGjk

Thanks,
Jerry Popiel

Thank you, Jerry! It’s amazing what performance you and Gary DeBock have gotten out of these homebrew FSL antennas! Thank you so much for taking the time to share your construction details and performance notes!

The Society of Broadcast Engineers urges FCC to Improve Mediumwave RFI

WHKY-AM-Radio-Tower(Source: ARRL via Eric McFadden, WD8RIF)

The Society of Broadcast Engineers (SBE) has told the FCC that the regulatory agency needs to take another tack in its efforts to tackle AM revitalization. If the FCC takes the SBE’s advice, the result could be less noise in the MF and HF Amateur Radio bands. In comments the SBE filed in response to an FCC Further Notice of Proposed Rulemaking and Notice of Inquiry (MB 13-249) proposing ways to enhance the viability of the AM broadcast service, the SBE said the Commission must “commit to a regulatory plan which, over time, will reduce the levels of man-made noise in the MF bands, and more broadly in the bands below 30 MHz.” In comments it filed earlier in the proceeding, the SBE pointed out that “AM radio in particular is susceptible to interference from electronic devices of all types,” and that ambient noise on the AM band is only bound to get worse with further proliferation of noise-generating electronic devices, including certain lighting devices regulated under FCC Part 15 and Part 18 rules.[…]
