Latest ARISS SSTV Project - no or very little signal
|
Floyd Bixler
Just had a very good pass from the ISS. Unfortunately, the SSTV signal was nil to none although the RF was, at my location, full quieting, albeit, also intermittent. This was a pass almost directly overhead from Germany (JN58).
Anyone else in Europe see this? Floyd DA1VF/WD8DUP

New Mexico, and I Experienced the exact same problem You did. At the 01:31 UTC pass here, an almost perfect Overhead pass, I had almost S9, full quieting Receive, but the SSTV audio was very faint, would not trigger My Robosat36 app. I have another pass here in a couple hours. Looking at the ARISS blog page others are Getting good copy, confusing Me! 73 Mark. KB7WAL

The 12:40 pass in Massachusetts is attached.
I used narrow band. This is my typical recording using my D72 and Diamond RH77CA with Robot36. I had similar results in a previous event with ‘poor’ audio.

It is Yuri's Day / Astronauts' Day in Russia ... appropriate powers-that-be ARE aware of the
audio problem ... but between it being a holiday and a weekend - well, we can just hope the audio situation is rectified. Clint

OK, Mark, then I can check off my new RTL-SDR dongle that came in yesterday as not being the problem (my FunCube Dongle went south on the same day). My last pass was nil; not even RF...
Hopefully they'll extend the dates or resked like last time we had this problem 73, Floyd DA1VF/WD8DUP

Why did you choose "narrow band?" Have your results with NB been better than Wide in the past?

Just had a 37 degree pass with 50 mph winds. Got the beginning and end of the pic because the wind blew the wire off my recorder. Low volume. Next pass I will try a preamp and see if it makes a difference.

In a previous event, I could not hear any SSTV audio in Wide. I tried Narrow and I could hear it. The reasoning: as I understand it, one of the radios used on the ISS is narrow band so I thought I would give it a try. It was during the previous event that had a period of poor reception. Both times was with my D72.
I did suspect my D72 of filter problems but I am fairly confident the D72 is okay.
