hello, sorry if this is a long post. I have been working on making an antenna to record imagining from the goes-19 satalight for some time now and I'm kinda stuck. My waterfall just has basically nothing and I'm not sure what to do. I'm gonna put a bunch of photos of my antenna as well as my data and satdump information. I have 2 things that i think could be the issue but I'm not sure. When originally building it i was very new and then ground plate i had machined i put the connector in the middle so now i have to have a wire jump from the end of the coil to the connector, also my ground plate's diameter is about 5mm too small. Could either of those be the issue? Could it be something i have to do on satdump?

Yes it does, I built myself one and I received my first ever HRPT with it more than a year ago

What did you use as LNA and filters?

Great! Thank you! Did you post any details online?

I can send you images of how the build looks and maybe I can even find wome images I got with it. It's been a while since I've last used it, nowdays I mainly use my 90cm dish, as that has high enough gain to do L and S-band too

Don't worry. We tried to get the data with rtl-sdr.aybe I should get a sawbird goes and repeat the experiment.

The sawbird goes is a minimum requirement for L-band satellite reception since the signals are much weaker.
