This is my first post on here, not sure if this would be suitable for the Gallery collection.
This picture is my first picture ever. I could not get any clear picture before, but after a ton of work making my antenna pick these signals up, I received the cleanest picture ever taken with my setup.
The picture depicts a picture of Antarctica, around the western side. I unfortunately cannot upload this to satNOGS since I use Windows and haven’t set up the API yet.
Its a home built QHF antenna, I find it works best in W FM set to 30kHz for a high elevation pass, if the pass is low you can reduce this to get a better image otherwise you pick up a lot of noise from the edge of the band.

Hi, degamisu
It might be a bad idea to revive this old topic, but, I’ve also just started my station and rather disappointed with quality of NOAA images. During daylight I can capture more or less stable images in SatDump from NOAA satellites using the same setup (Discone antenna, V4 Blog, max gain). However, my SatNOGS client always produce fuzzy images, lest in false color.
Would you like to suggest or share settings for your client?
a bit of thread-hijacking, yes (:
I’d say the max gain is the main issue here, as you can see in the horizontal lines both in the waterfall and the resulting image. FM-bandstop might be useful, but that is just a guess.
Great picture. Good contrast between black and white. Some noise & interference, but a satisfying start. You are well on the way. I also started by chasing the NOAA satellites.

I’d like to ask some more questions to clarify my understanding working ins and outs)
satnogs-client has everything to process and decode signals - no need for external apps, manual install addons/scripts?
Btw, here is sample of NOAA and Meteor images captured using the same setup (antenna, no pre-amp LNA, no filter) with SatDump. sample images
As you could see, there is no problem with receiving signals. Not stables, of course, but it works. I hope, that playing around with gain (or some other settings) will improve quality.
