VOA Radiogram program 61 reception

Sat 31 May 2014

pic_2014-06-01_024620zJust copied program 61 of the VOA Radiogram on 5145.  The program was transmitted from the Edward R Murrow Transmitting Station down in Greenville, NC.  I've seen this place many times and am happy to have copied its transmission now.  I'm also lucky that I was watching Twitter just before the program started and was reminded to tune in.

VOA Radiogram soon at 0230 UTC on 5745 kHz http://t.co/LJJSBswmQh #shortwave

Here is the text as I received it.

Welcome to program 61 of VOA Radiogram from the Voice of America.

I'm Kim Andrew Elliott in Washington.

On today's program, instead of the usual news stories from VOA
News, we will experiment with the transmission and decoding of
images.

In the first part of today's program, we will experiment with
MFSK images. Later in the program, an EasyPal digital image will
be transmitted. (Please start your EasyPal software.)

Please send reception reports to radiogram@voanews.com.

And visit voaradiogram.net.

MFSK IMAGES

The Fldigi software allows for the transmission of MFSK images at
different speeds: X1, X2, and X4. X2 and X4 "paint" more quickly,
but result in lower resolution: X2 is fuzzier, and X4 is
fuzziest. (Fldigi software is required to decode the X2 and X4
images.)

As the symbol rate (baud) of the MFSK modes increases from MFSK32
to MFSK64 to MFSK128, the resolution of images sent in those
modes also increases. The time required to send a picture is the
same for MFSK32, MFSK64, and MFSK128.

We therefore have two variables: the transmission speed and the
symbol rate of the MFSK mode.

We will transmit the same VOA Radiogram test card (254x197
pixels) as follows:

MFSK32 X1
MFSK32 X2
MFSK32 X4

MFSK64 X1
MFSK64 X2
MFSK64 X4

MFSK128 X1
MFSK128 X2
MFSK128 X4

First the MFSK32 images in X1, X2, and X4...

If you have not done so, please start your EasyPal software.

It has been several months since we have experimented with the
EasyPal digital image mode on VOA Radiogram.

EasyPal is the work of Erik, VK4AES, in Australia. His software
uses DRM (Digital Radio Mondiale) encoding to allow the sending
of image files over an HF or VHF using only 2.5Khz (same as
voice). EasyPal is also known as Digital SSTV (slow scan
television).

Next on VOA Radiogram will be an EasyPal text transmission,
followed by the same VOA Radiogram test card that was transmitted
in the MFSK modes. The card will be larger and in higher
resolution. The picture transmission will be just over 7 minutes.
The picture might appear before the 7-minute transmission is
completed, or it might not appear at all -- there is a rather
high failure rate with EasyPal on shortwave.

Now the EasyPal transmissions...
