SSTV Sig's from ISS on 145.800 were quite loud this afternoon. SNRs we're as great as 50 dB with either an Arrow J_Pole or an M2 Eggbeater up only 7 feet.
Rx is a Fucube Pro+ using SDR Console v3.0.5
Noise floor with 12 kHz bandwidth was -97 dBm, and signals were consistently better than -65 dBm, peaking -44 dBm at times.
Pix Quality was excellent.
Whatever problem was there last week is not there now. Much appreciated!

All,
The ARISS team expects that a second SSTV transmission event will occur from ISS this weekend.
ARISS Russia team member Sergey Samburov, RV3DR, worked with the mission control center flight controllers to schedule in ISS crew member time to configure the JVC Kenwood radio to support SSTV operations in the Service Module. SSTV setup is expected to start around 8:45 UTC on February 15 and conclude around 17:25 UTC on February 17. These dates/times are expectations and may vary.
The ARISS team wanted to give the community another opportunity to downlink the SSTV images we developed for you given the weak signal situation that occurred last weekend. For clarity, these will be the same 12 images that were downlinked last weekend.
As a reminder, you can get the latest SSTV information on the ARISS SSTV Blog Spot: http://ariss-sstv.blogspot.com/ http://ariss-sstv.blogspot.com/ Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php http://www.spaceflightsoftware.com/ARISS_SSTV/index.php And you can receive a special SSTV ARISS Award for posting your image. See https://ariss.pzk.org.pl/sstv/ https://ariss.pzk.org.pl/sstv/. For simplicity, we have added a new tab for SSTV, under general contacts, on the ARISS web site http://www.ariss.org www.ariss.org
For those that are asking, we are still not totally clear what caused the issue last weekend. We believe it may have been either a loose feedline cable or an antenna switch that did not fully engage. Once the crew reset the system and checked the cabling and switches, the radio system started to perform nominally.
Enjoy!!
