    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!

    First round cracked a bit on the top but damn these are good!

    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.

    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.

    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.

    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.

    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.

    ✅ Satellite predictions ✅ 120° dipole (52cm rods) ✅ SDR device ✅ Recording + decoding software Now I just need to wait for a good flyby and hope there isn't too much interference.

    For anyone interested in trying this, I found a website that interpolates their location and also lists their individual downlink frequency. NOAA 15: NOAA 18: NOAA 19: It even estimates the next flyby.

    Sometimes he just gets lucky though... (Or is a good enough actor to make it look like luck)

    Also, you people are going to get Trump reelected with this nonsense. Stop it.

    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.

    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).

    🤦‍♂️ Social media was a bad idea. The level of psychotic conspiracy theory peddling, fearmongering, and grifting is just unbelievable.

    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!
