Are you ready for SSTV yet?

If the SSTV project is activated from ISS, then we may only see a few hours of activation during the 10 day mission.

In last memo, I omitted the link page where I keep some of my SSTV software links.

Thanks to a reminder from WB2LLP   Gene Marks, I have updated the software page links.  This page will provide you with a few SSTV software options, (there are many more out there), it will give you a good place to start surfing to learn about SSTV and a few of the available applications.

Is SSTV on VHF different from SSTV on HF?  

No, SSTV is the same on HF and VHF.  When someone says they are sending "Robot-36" it’s the same format for all bands.  HF usually runs SSB and VHF usually run FM.  Most Radio voice modes will work for sending SSTV.  There are also a few flavors of Digital SSTV; however that’s beyond our scope at this time.  The International Space Station will be using Analog SSTV in Robot-36 Mode.

Slow Scan TV Links and Free SSTV software links.

The standard downlink of 145.800 will be used for voice contacts, school contacts and SSTV transmissions. Anyone with a FM receiver capable of monitoring the 145.800 MHz downlink can receive audio and SSTV images. The standard voice uplink frequencies of 145.200 for ITU Region 1 (Europe, Africa and Russia) and 144.490 for ITU regions 2 & 3 (N. America, S. America, Southern Asia, Australia) will be used. 

Additional info on SSTV operations is available at:

Ground stations are encouraged to capture as many of the transmitted
SSTV images and forward them to the Marex at SSTV at ISSSPACECAM.ORG

After you receive an image, please rename the images using the following
format, (All Lower case letters). All dates and times must be in UTC.  

Year 08, Month 10, Day 14, (UTC time), Call sign,

We would also like to know the following information in your email:
Name or Call sign
Country / State

Slow Scan TV:
The Marex Slow Scan TV project, SpaceCam1 was activated for a few weeks in August 2006.  We hope to see some new images in October 2008
