Recent pass was marginally better. You can see the signal fading out a bit on the waterfall. May look to see if there’s something I can tweak to get a better signal before tomorrow.

It’s got a learning curve but I really like it. I have the Pis mounted in that enclosure in my garage, and then the antennas are in the attic space above, with coax running down some conduit into the enclosure. With a browser I can access the SDRs from anywhere on my network.

This is my best result from a nearly direct overhead pass just about 10 minutes ago.

It also can report to wspr, pskreporter, and others. You can schedule when it tunes to certain bands, and it will background decode whatever you've set it to. So I have one SDR set to listen to 20m/40m/80m throughout the day. And then the other SDR listens to 2m all day. Third pic shows that.

Doing a little bit better than me.

Turns out an RTL-SDR Blog v4 and 80 feet of wire strung up around the ceiling of my garage can hear radio signals from pretty far away.

Ah, good old Draino. He blocked me after I kept responding to his tweets with this screenshot.

Just started as well, and this made my jaw drop.

Upgrading to a proper ADSB antenna made a huge difference in performance for my feeder. 3x the number of aircraft seen, almost 4x the message rate. Range is not quite as dramatic but the new peak is 266 miles compared to 238 before.

This is pretty nerdy, even for me.

On a roll this week; designed and printed a custom bracket to hold my SDRs in place in an enclosure.

Do those graphs come from FlightAware’s software? They’re way prettier than mine.

It’s pretty cool that I can design something to solve a problem I have and then just print it out on my 3d printer.
