ARLS002 ARISS Plans Do-Over of Slow-Scan TV Transmissions over

February 15 - 17 Weekend


Amateur Radio on the International Space Station (ARISS) is planning

another popular slow-scan television (SSTV) event in the wake of an

SSTV experiment last weekend, during which signals were reported to

have been weak. Even so, more than 5,500 images were submitted.

Transmissions are scheduled to begin on Friday, February 15, at 0845

UTC and run through Sunday, February 17, at 1725 UTC.


"The ARISS team wanted to give the community another opportunity to

download the SSTV images we developed for you, given the weak-signal

situation that occurred last weekend," said ARISS-International

President Frank Bauer, KA3HDO. He clarified that the same 12 images

transmitted last weekend will be used for this weekend's experiment.


Bauer said it's not entirely clear what caused the low-signal issue

last weekend. "We believe it may have been either a loose feed-line

cable or an antenna switch that did not fully engage," he said.

"Once the crew reset the system and checked the cabling and

switches, the radio system started to perform nominally."


ARISS-Russia team member Sergey Samburov, RV3DR, worked with flight

controllers to schedule ISS crew time to configure the JVC Kenwood

radio to support SSTV operations, which take place from the Service

Module. SSTV images will be transmitted on 145.80 MHz using

SSTV-mode PD120. These can be received using equipment as simple as

a 2-meter handheld radio, a scanner that covers that band, or even

an online WebSDR receiver. Copying the images is as simple as

connecting the receiver's audio output to the audio input of a

computer running free software such as MMSSTV.


Transmissions will consist of eight images from the NASA On The Air

(NOTA) celebration and four ARISS commemorative images. Received

images can be posted and viewed online. ARISS offers an ARISS SSTV

Award for those who receive and decode at least one SSTV image in

the session.


As always, this SSTV event is dependent on other activities,

schedules, and crew responsibilities on the ISS and are subject to

change at any time. Check for updates on the ARISS or AMSAT

  • Reminder: JS8 QSO Party When: Saturday, 9 November 2019, 7:00pm to Sunday, 10 November 2019, 7:00pm (GMT+00:00) Africa/Monrovia Where: All Amateur bands, HF, VHF, & UHF View Event Organizer: kn4crd@gmail.com Description: The JS8 QSO Party is a chance to get on the air with JS8 and make some contacts every month. Whether you like a quick exchange or a long rag-chew, this event is for you. We have a lot of great, patient operators in the group, so the environment should be very welcoming!
  • It's been wide open on FT8 since late this afternoon until after supper. Worked France, Hungary,Italy,Switzerland,Portugal (twice), Slovenia, Colombia. I tried really hard for Guernsey but although he heard me and I heard him initially, we couldn't make the final exchange. That's a fairly rare one so it was disappointing to not get him!
  • The 15m band is open for FT8 contacts right now. Mostly western US (California) and a few weak South America stations
