2 top images are same attempt - with and without auto-slant
Something screwed up. Probably with the audio recording, perhaps it dropped a few samples so QSSTV desynchronized there.
Boring setup:
V-Dipole, RTL-SDR v3, waterproof smartphone (it was snowing, else I'd bring a laptop)
That download button on top is to save the image without loosing quality, just in case.
~~Did you just use speaker + microphone or cable?~~ Nevermind, there's no headphone symbol.
Couldn't find the image on my phone, so that was good enough.
Just held the phone near the radio cranked up the volume.
