VOA Radiogram features EasyPal digital images this weekend

VOARadiogram(Source: VOA Radiogram)

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

Shortwave Radio Recordings: Radio Australia’s Jazz Notes

Jazz Notes showcases the best in Australian jazz, often featuring new and original recordings made in ABC’s studios. The show is hosted by Ivan Lloyd and has been offered on Radio Australia for several years.  I listen to the show Wednesday mornings at 9:30 am EDT.

The Age National Times: Radio Australia may cut broadcasts to China/Indonesia

ABC-Radio-AustraliaThanks to Richard Cuff for bringing this item to my attention:

(Source: The Age – National Times)

The ABC could soon abandon international shortwave radio broadcasts to China and Indonesia, ending more than 70 years of beaming news and current affairs on high frequency into Asia.

But the public broadcaster’s management insist it will not flick the switch on shortwave services of Radio Australia to Papua New Guinea and tiny Pacific nations for now.

ABC international chief Lynley Marshall said the older shortwave technology was still relevant in the Pacific, despite a drive to make mobile and internet devices the ”primary” way of delivering news.

Staff had grown increasingly alarmed in recent months that the shortwave service to the Pacific would be canned – including a popular Tok Pisin [a service we recently mentioned] to PNG – raising fears expats and locals would be vulnerable to dangerous news blackouts during natural disasters or regional strife.

Radio is the cheapest and most widespread source of news in poorer Pacific provinces. Most nations run only a 2G mobile network with little coverage outside capitals. When Prime Minister Julia Gillard visits Port Moresby on Thursday almost twice as many locals will hear news of the trip on radio than see it on television or read it in newspapers.[…]

Richard also posted this relevant comment in the SW Programs discussion list:

[…]I believe this would be the service more audible in Western Europe.

However the Pacific service – which is the service we’re more likely to hear in North America – appears to be safe for now, as mobile/Internet technologies aren’t adequate enough in that region.

Radio Australia has become my staple, reliable shortwave radio news and entertainment source. I certainly hope RA does not cut services in the same manner as RNW or RCI.

Radio Free Sarawak takes a break

RadioFreeSarawakThe clandestine station Radio Free Sarawakwho we most recently mentioned in connection with the Malaysian elections–has announced that they are going off the air.  There is a note of finality in their announcement (below), yet they do leave some ambiguity by declaring, “We will be taking a break until further notice.”

[UPDATE: Radio Free Sarawak back on the air 12 August 2013]

Listen to their final broadcast (studio copy) embedded below:

While most PR supporters are still reeling from the results of the GE13 amidst widespread rigging that are essentially acts of treason, activists and ordinary people alike are not giving up on booting out the BN government The have set their sights on the 11th state election that will have to be conducted latest by early 2016.

Meanwhile, take a listen to the analysis of Dr Mohd Faisal Syam Abdol Hazis from the Universiti Malaysia Sarawak of the results in the state.

Last but not least, we hear the sadness, anger, frustration and nevertheless, determination of RFS and PR supporters to realise the dream of changing the government in the near future.

p/s Today’s show will be our last. We will be taking a break until further notice. Thank you for your support. It will be a memorable 18 months! We hope you had enjoyed the experience as much as we did.
