Software Defined Radio Operational

ND8D has installed a SDR in the WC8VOA operating room.

The SDR allows you to monitor many of the SW bands, and you can check you signal by transmitting from home and listening to how you sound when received at WC8VOA.  The unit is presently connected to the fan dipole.  Four simultaneous connects are possible.

ARISS Celebrates it’s 20th Anniversary through SSTV Event

In commemoration of the 20th Anniversary of ARISS, a Slow Scan Television (SSTV) event is planned for Thursday, July 20 starting around 21:25 UTC.  The event plans to feature images from ARISS activities both past and present. This opportunity should cover most of the world during the operation period.

The event plans to use a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the ham radio, specifically the onboard Kenwood TM D710 transceiver. Those receiving the images can post them at https://ariss-sstv.blogspot.com/ for viewing by the public.

The 20 year history of ARISS will be displayed through a collection of 12 unique images sharing the amazing accomplishments of ARISS over the last two decades. SSTV signals will be sent to earth at 145.80 MHz using FM. The SSTV mode of transmission is expected to be PD 120 (PD 180 may be a second option). The event is expected to continue over a two day period.

Since it’s inception, Amateur Radio on the International Space Station (ARISS) has provided students an opportunity, through ham radio, to engage in conversation with orbiting astronauts and inspired many to seek careers in science, technology, engineering and math. Consider how you might inspire students in your area through this chance to capture images directly from space to their computers.

Please note that the event, and any ARISS event, is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time.

While preparations are being finalized please check for new and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB@amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status for the latest information on this event.

You can use the AMSAT website to do ISS Pass Prediction for your area.
You will need software to decode the pictures, for the PC there’s MMSSTV. You can also decode the pictures from your smartphone, yep there’s an App for that. I use CQ SSTV for iOS(Apple), there’s also Robot36 for Android.

Good luck!
