VOA Radiogram features EasyPal digital images this weekend

During the past weekend, EasyPal digital images were received successfully throughout Europe and North America. You can see a gallery of some of the received images here:

voaradiogram.net/post/51385444401/voa-radiogram-easypal-images-received-100-or-0

Reviewing the advantages of EasyPal versus MFSK32:

EasyPal:

1) When received successfully, the picture is perfect.

2) Takes less time to transmit than MFSK32 and most SSTV images of the same size.

3) No problems with slant if soundcards are not calibrated.

MFSK32:

1) If the signal drops below a certain level, or if interference exceeds a certain level, no EasyPal image will be received at all. Under similar reception conditions, MFSK32, which uses an analog frequency shift keying system for images, will allow the an image to be seen, even if the quality is not perfect.

2) MFSK32 images allows images of different heights and widths, including small images which can be transmitted quickly. The gray tone MFSK32 image option allows even faster transmission.

3) MFSK32 images can be decoded by more than one software program under more than one operating system. There is only one EasyPal program, and it works only under the Windows operating system.

I welcome your comments and suggestions about the transmission of images via shortwave broadcast. Weighing all of the above factors, I am inclined to adopt MFSK32 as the primary image mode for VOA Radiogram. However, the EasyPal images are so impressive that I will continue to include some in future programs.

On VOA Radiogram for the weekend of 1 and 2 June 2013, we will continue to compare MFSK32 and EasyPal images. Here is the lineup for the program:

3:44    MFSK16: Program preview
3:17    MFSK32: VOA News story about Olympics wrestling
3:16    MFSK32: VOA News story about 2013 hurricane season
1:10    MFSK32: File image of Atlantic hurricane
2:53    MFSK32: VOA News story about colliding galaxies
1:04    MFSK32: Image of the colliding galaxies
1:21    MFSK32: Introduction to MFSK64 and EasyPal
1:30    MFSK64: Same VOA News story about colliding galaxies
:39     EasyPal text: Same VOA News story about galaxies
2:38    EasyPal image: Colliding galaxies
2:38    EasyPal image: Soyuz capsule being moved to launch site
1:09    MFSK16 closing announcements
:29     Surprise mode of the week

VOA Radiogram for April 27/28 includes Thor50x2, PSK63F, and Flamp

Apologies for not updating this website since the April 20/21 VOA Radiogram. I have been diverted by deadlines connected to my other full-time job, audience research analyst for the International Broadcasting Bureau.

Thanks to all who sent reception reports, screenshots, audio samples, and other materials from the past weekend’s program. MFSK held off a challenge from the Thor modes and remains the most successful of the modes we have tested.

However, because your producer omitted the Thor 50×2 mode — a mode that might prove to be robust — from that program, VOA Radiogram on April 27/28 will include a “make good” transmission of Thor 50×2. And a transmission of Thor 50×1 for comparison.

There will also be a transmission of the PSK63F mode. This rather slow mode performed well during VOA Radiogram 1, but we only gave it a minute. There will be a longer transmission of PSK63F this weekend to allow a better evaluation.

The last text transmission this weekend will be in the Flamp format. If you don’t already have it, please download Flamp from www.w1hkj.com. Flamp divides a text file into several blocks, each with a specific number of characters. If any block is received without the correct number of characters, that block is rejected. The missing block can be picked up during the repeat transmission. Flamp might be useful for those text transmissions that are received at about 90% copy, when occasional deep fades prevent 100% copy. In Flamp, under Configure, check both of the Auto sync boxes.

Here is the lineup for the April 27/28 VOA Radiogram:

MFSK16 (58 wpm) program preview
PSK63F (55 wpm), 2:50
MFSK32 text (120 wpm) and image, 4:28
Thor50x1 (180wpm), 1:48
Thor50x2 (180wpm), 1:46
MFSK64 (240 wpm), 2:16
MFSK128* in Flamp X2 format, 3:46
MFSK32 image

*Probably a good idea to set the MFSK128 mode manually rather than depend on the RSID

All modes will be centered on 1500 Hz.

Each mode will be introduced by a brief MFSK16 transmission, same as last weekend.

Heritage Foundation: BBG is cutting “the most cost-effective part of its organization”

Leave a reply

For those of you not familiar, note that the The Heritage Foundation is a US conservative think tank based in Washington, D.C. whose mission is to “formulate and promote conservative public policies based on the principles of free enterprise, limited government, individual freedom, traditional American values, and a strong national defense.”

(Source: Heritage Foundation)

The Broadcasting Board of Governors (BBG) recently informed its workforce about sequestration cuts to Voice of America’s (VOA) shortwave and medium-wave broadcasting. Ironically, the Board is cutting the most cost-effective part of its organization: radio.

It would be more rational to cut the bloated management and administration of the International Broadcasting Bureau, which accounts for over 36 percent of the 2013 BBG budget request. Television broadcasting would also be a good place to look for savings, being far more expensive to produce and highly variable in terms of ratings.

Last year, however, the BBG declared in its “Strategic Plan” that radio is a “legacy medium,” a hold over from the past compared to television and the Internet. Now a golden opportunity has presented itself for the BBG staff. Thus, under the guise of complying with sequestration, the board has moved ahead with plans to cut radio, plans that have been fought by Members of Congress and heavily criticized by supporters of U.S. public diplomacy for several years.

One vocal critic was former Secretary of State Hillary Clinton, no less. During her Benghazi testimony in January, Clinton had harsh words for the BBG. Clinton bemoaned the fact that the U.S. government has “abandoned broadcasting to the Middle East,” and stated that the BBG, which is responsible, is “a defunct agency.” While this is hardly true in terms of budget, it is in terms of leadership.

Under sequestration, the BBG must cut $37.2 million out of its total budget of $720 million. The announced cuts in shortwave and medium-wave broadcasting are a drop in the bucket, a mere $5.3 million. While efficiencies should certainly be part of the budget picture, decimating the agency’s core mission—broadcasting—should not. Moreover, management has made it clear that these cuts are permanent and not reversible.

[…]It means deep cuts in broadcasting in Cantonese to China, Dari and Pashto to Afghanistan, English to Africa and Asia, Khmer to Cambodia, and English-learning programs around the world. It further means elimination of medium-wave and shortwave broadcasting in Albanian, Georgian, Persian, and Spanish, as well as in English to Afghanistan and in English to the Middle East.

The document notes that national FM and television affiliates will continue to carry VOA broadcasting. The catch is that local affiliates are subject to the whims of the host countries, with all the vulnerabilities and complications that entails.[…]

Shortwave Radio Recordings: VOA Special English

Leave a reply

I believe that VOA Special English may be one of the best educational resources on the shortwaves. At Ears To Our World, we find that it is often the most popular program in countries where English may be the official language, but where locals only speak it as a second language.

Over four years ago, I mentioned a Special English broadcast honoring Henry Loomis, the creator and champion of Special English at the VOA. Click here to read the archived post.

I recorded this particular broadcast of VOA Special English on March 19, 2013 at 1:30 UTC on 5,960 kHz.

VOA reducing shortwave radio broadcasts

2 Replies

VOA Following the BBC World Service’s lead, the VOA will reduce broadcasts to Iran, Albania, Georgia and Latin America, along with English language broadcasts to the Middle East and Afghanistan.

Full details below:

(Source: Inside VOA)

WASHINGTON, D.C. — Voice of America is reducing some of its radio transmissions this weekend and ending shortwave broadcasts to regions where audiences have alternative ways of receiving VOA news and information programs.

The transmission reductions allow VOA to comply with budget cuts required by sequestration and to avoid furloughs of staff members.

When the new broadcast schedule goes into effect on March 31st, cross-border shortwave and medium wave broadcasts to Albania, Georgia, Iran and Latin America will be curtailed, along with English language broadcasts to the Middle East and Afghanistan.

VOA will continue to provide audiences in these regions with up-to-date news and information through a host of other platforms, including radio and TV affiliate stations, direct-to-home satellite, web streaming, mobile sites and social media.

The new broadcast schedule calls for reductions in some shortwave and medium wave radio broadcasts in Cantonese, Dari/Pashto, English to Africa, Khmer, Kurdish, Mandarin, Portuguese, Urdu and Vietnamese. Direct radio broadcasts to all of these regions will continue.

The transmission reductions are expected to have minimal impact on audience numbers since primary modes of delivery will remain. Shortwave and medium wave broadcasts will continue to regions where they draw substantial audiences, and to countries where other signal delivery is difficult or impossible.
