Walt’s decoded image from “The Classics Experience”

Many thanks to SWLing Post reader, Walter Salmaniw, who comments:

ClasssicsExperienceI reviewed Paul’s excellent program this morning and worked on decoding the image broadcast during his 2nd hour.

Unfortunately the slant was all wrong! But gradually, working the slant on the Fldigi resulted in a nice image of his dog [see image on right], using about -6250 (Configure > Soundcard > Settings >RX Corrections.

Thanks for a great program, Paul!

Thanks for sharing the image, Walter!

Paul, I think it’s brilliant that you included your beagle in the show! Thanks for putting the great tunes and content on the air!

ISS Slow Scan TV in April

ARISS reports that International Space Station (ISS) Slow Scan Television (SSTV) transmissions on 145.800 MHz FM may take place between April 11-15, 2016

The schedule for the ARISS commemorative event is currently:
• Setup and activation on April 11 about 18:25 UT.
• Paused April 12 from 12:15 until 14:15 UT to allow for a school contact with Romania.
• Paused April 13 from 12:45 until 14:30 UT to allow for a school contact with Argentina.
• Deactivation on April 14 at 11:35 UT.

This opportunity should cover most of the world during the operational period. The image transmissions should be on 145.800 MHz and the mode is planned to be PD180.

In addition, MAI-75 (SSTV Experiment) will be conducting two sessions afterwards. The first one is April 14 from 14:45 until 18:00 UT.
The second session is on April 15 from 14:10 until 19:00 UT. These times do not cross N. America but will provide opportunities for Europe, Southeast Asia, Australia and S. America.

SPROUT SSTV and Digitalker Every Sunday

SPROUT SSTV and Digitalker active every Sunday

SPROUT SSTV and Digitalker Active Every Sunday – AMSAT-UK

AMSAT-UK Announces SSTV Activity Every Sunday

Slow Scan TV (SSTV) images in Scottie 1 format will be transmitted from the SPROUT satellite every Sunday (Japanese Standard Time) on 437.600 MHz FM (+/- 9 kHz Doppler shift). The Digitalker will also be active.

SPROUT, a 20 x 20 x 22 cm amateur radio nano-satellite with a mass of 7.1 kg, launched successfully with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz) Synthetic Aperture Radar (SAR) satellite ALOS-2 on May 24, 2014 at 0305 UT. SPROUT is in a 654 km, 97.9 degree inclination Sun Synchronous Orbit (SSO).

SPROUT (Space Research On Unique Technology) was built by students from Nihon University

— A FM Digitalker will enable the satellite to speak to amateurs around the world.

— The Voice Message Box will record transmissions from radio amateurs and play them back.

— Pre-loaded images from the Message Gallery can be transmitted using Slow Scan TV (SSTV).

— Pictures of the Earth can be transmitted by SSTV and radio amateurs can receive it using free software such as MMSSTV. As part of the Earth mapping project the team ask radio amateurs to contribute pictures they have received from the satellite for display on the SPROUT website.

Size: 214x210x220 mm

Weight: 7.1 kg

Mode: 1200bps AFSK, 9600bps GMSK

CW downlink 437.525 MHz

FM packet downlink 437.525 MHz

Digipeater uplink 437.600 MHz

Digitalker downlink 437.600 MHz

SSTV downlink 437.600 MHz

Many FM radios can be switched been wide and narrow deviation FM filters. For best results you should select the wider filter designed for 5 kHz deviation FM.

Pirate Radio Recordings: Wolverine Radio

SWLing Post reader, Steve Yoth, decoded this Wolverine QSL two weeks ago using a Flex 3000.

A previous eQSL from Wolverine Radio. Try decoding the one at the end of this recording! 

For your listening pleasure: 1 hour, 20 minutes of the pirate radio station, Wolverine Radio–recorded May 26, 2014 starting around 1:20 UTC.

Wolverine was broadcasting on 6,950 kHz in the upper side band. Typical of Wolverine, lots of music variety which spans the decades and no commentary other than station ID throughout.

At the end of this recording, you’ll hear an SSTV QSL card being transmitted.

Try decoding the QSL image from this recording–it’s quite easy! I usually decode Wolverine’s SSTV QSL with Chris Smolinski’s SSTV app for iPhone, but there are other programs to do this. The eQSL above came from a broadcast about two weeks ago and was submitted by SWLing Post reader, Steve Yoth.

Pirate Radio Recordings: Wolverine Radio

SSTV-28Apr2014-080706For your listening pleasure: 1 hour and 7 minutes of pirate radio station, Wolverine Radio–recorded April 27, 2014 starting around 1:10 UTC.

Wolverine was broadcasting on 6,945 kHz in the upper side band. Typical of Wolverine, lots of music variety which spans the decades and no commentary other than station ID throughout.

I decoded Wolverine’s SSTV QSL (see right) with Chris Smolinski’s SSTV app for iPhone.  As you’ll hear, overall signal strength and audio fidelity were excellent.
