I'm going to consider this a success. The satellite signal was caught from indoors using the same antenna/demodulation setup as before but this time NOAA 15 flew almost directly above Austin. Unfortunately it's really cloudy today, but still... It works!pic.twitter.com/sXXJDFcKpE

First round cracked a bit on the top but damn these are good!pic.twitter.com/VUO2VzZaPY

The signal from this one is too weak for an image (it's east of FL and I'm in TX) but this is what their waterfall plot looks like for anyone curious.pic.twitter.com/2Thw2EcNrZ

I'm gradually getting better at capturing these. So far the best demodulation settings seem to be using a bandwidth of 45 kHz, a narrow FM with maximum deviation of 17 kHz. Still using a horizontal 120° dipole 52cm rods.pic.twitter.com/4K7ExAFc94

Caught some signal from NOAA 18. It was over CA and I'm receiving from TX so there was a lot of noise. But still better than my first attempt.pic.twitter.com/SkShLpnL2H

Got a much better capture this morning. Last night there was an interference source pulsing about every 5 seconds. It's gone today but I only caught the tail end of this pass (by accident!). Now I know that I can do it as long as I time it right and don't have that interference.pic.twitter.com/2PvmolLwuM

I was definitely able to pick up the signal (you can see the left vs right channels in the image and the right-hand bars). But it's SUPER noisy. Not sure if I just need a better antenna setup or if I need to go out in the hill country some day and try this away from noise.pic.twitter.com/mOzT1cBy6v

Now I just need to wait for a good flyby and hope there isn't too much interference.pic.twitter.com/jbJJGc1AwF

For anyone interested in trying this, I found a website that interpolates their location and also lists their individual downlink frequency. NOAA 15: https://www.n2yo.com/satellite/?s=25338 … NOAA 18: https://www.n2yo.com/satellite/?s=28654 … NOAA 19: https://www.n2yo.com/satellite/?s=33591 … It even estimates the next flyby.pic.twitter.com/2PLi8Ybjar

Sometimes he just gets lucky though... (Or is a good enough actor to make it look like luck)https://www.youtube.com/watch?v=lT3vGaOLWqE …

While it's more common to saute bitter melon (especially good with eggs) I've found that they make surprisingly good pickles. A slightly sweet, spicy bitter melon pickle hits all of the sweet/spicy/sour/salty/bitter flavors.pic.twitter.com/9DJCsgVrGy

I'm a fan of bitter melon and enjoy both the Chinese varieties and the Indian ones but today something stood out in the produce section... Taiwanese white bitter melon? It's adorable. Similar in taste to the Chinese ones (maybe a bit more mild).pic.twitter.com/efBM9CRRiL

Social media was a bad idea.
The level of psychotic conspiracy theory peddling, fearmongering, and grifting is just unbelievable.pic.twitter.com/rBJNuD4dFo

Something I didn't show in the video was that I also ended up turning another ESP32 into a proxy to extend the reach of my WiFi into my backyard to test the camera from one of my nest boxes!pic.twitter.com/1CGJbNliDd
