I see some people who like to decode the image in realtime with an app or a laptop. If you're at home, sure, knock yourself out. I prefer to record the audio, and then process the audio on an app afterwards. This way, if there are any noises, I can re-run the app with a few changes to try and get the best image possible.
The biggest tip I can provide from my experience is to not move the antenna during the transmission. My cleanest images have been from my car antenna, or moving my Arrow Antenna only twice (AOS heading, midway, and LOS heading).
