I just had an 84 degree pass but even after enhancing the sound file no images could be decoded. What amazed me was the signal strength that I got with my Xpol 5 element beam: when the ISS came on it was full quieting. Never heard them so strong before, but then again, I never used a Xpol beam to receive the ISS.
Hope someone can contact the ISS before the weekend is over.

Hi!
I just had a 44-degree pass over central Arizona around 0130 UTC. One of the two pictures I copied came in at the middle of the pass, yet QSSTV would not decode the WAV file from my TH-D74 HT until I amplified the recording by 20dB using Audacity. Then I saw one really good picture, and an OK second picture from the transmission just before my LOS. The audio files from this pass, including the WAV files converted to 48kbps and with the 20dB amplification, are in the "201904-ISS_SSTV" folder in my Dropbox space:
One more pass at 0300 UTC, with maximum elevation of 12 degrees. Then I'm done until tomorrow morning, if I get breaks coinciding with ISS passes...
73!

Same here. Good, strong signals on a low pass, but QSSTV couldn't sync. Got a partial image from enhancing the recorded audio.
In the same pass they transmitted another image, but couldn't even hear and see any SSTV, only a strong carrier.
