Please provide reception reports by posting to this topic. It would be good if you could include details of Dish size, receiver, decoding software, reception time, reception duration, peak MER and picture content.
(as an example: 80 cm dish, G4DDK preamp, Calafornia Amplifier downconverter, PicoTuner and Ryde, start 1505 UTC, end 1508 UTC, peak MER 8 dB, blank raster)
Thanks
Dave, G8GKQ

I've just seen it on a second pass (1642 to 1645 UTC) as well. It's a strong signal - here is the spectrum on BandViewer (note that my IF is 731 MHz)

Congratulations Dave. You were getting better results than me I could only manage MER 8.9 on the second pass. The first pass was a failure so nothing to report.
Dish - 1m Prime Focus Mesh, LNA TQP3M9073 Ali Exp, Minitiouner for receive. Only 2 mins receive 16:43 to 16:45, MER 8.9, C/S HAMTV, Black Screen.
Photo won't upload as file too big so I will put it on my Bluesky page.

Glad to join this forum. I am working to have the setup for ISS HAM TV RX. I will be watching the ARISS Live stream at 12:40 ,14:15,15:50, and 17:28 UTC when the ISS has the foot print over UK.

First reasonable report from me...
150 cm dish, POTY feed, G4DDK preamp, 'pipe cap' filter, Kuhne Downconverter, Portsdown Rx, start 1417 UTC, end 1422 UTC, peak MER 17.
Portsdown shows a squashed image (vertically) and squashed overlay text, anyone else get that?
Pass was up to ~40deg elevation, signal has lots of fading until it gets past south heading east, then it's much stronger.
Sun vs cold sky noise is ~8dB today.

Hi Rob
Yes - I had similar results with the Portsdown. I think that it is because the transmitted (blank) raster is 352x480, so much smaller than the touchscreen. Hopefully it will at least grow to 720x480 (which it was when we last saw a picture) when a camera is connected.
8 dB of sun noise is impressive. I only achieve about 1.8 dB. My MER on the 1420 UTC pass reached 15 dB though, but it was higher elevation at 73 degrees for me.
