Anyone here messing around with SDRs? I have this $30 USB stick radio plugged into a Raspberry Pi upstairs, The USB stick has an antenna connected to. I am running SDR++ server on the PI, and can tune to anything in the air from 100Khz to 1.75Ghz from my Macbbook pro Client. . I am a newbie when it comes to this stuff, but it is pretty cool. I can pick up a lot of stuff, including the local HAM repeaters, Air traffic, FM radio, and a lot more. I have also been messing around with a program called SDRTrunk. It is basically a digital scanner so I can pick up local digital trunked radio system in my town (EMS, Constables etc) Basically does the same thing a $600 scanner does, but a lot cheaper.

I do some for work and hobby. Have lots of rtl sdr, ni usrp on 800Mhz, hackrf, limesdr mini, bladerf and others.
Use lots of different software stacks but do development with GNUradio. Lots of fun doing different things on different bands. Not really a big scanner guy but lots of friends are. Have done gsm and lte base stations among other stuff. Really a game changer for development.
Where you located? I try to get hams interested but many of the older crowd are not software enthusiastic.

I'm in Conroe, the police here are all encrypted, even the dispatch, so that's a bummer.
There is a HAM repeater on North Frazier that I can tune to that is pretty active. I don't have a HAM license, but I picked up a $20 BaoFeng radio on Amazon, just to have in case of emergency where cell sites are down. I actually had that before I got the SDR. Then wanted to hear more bands, so got the 'listen only' SDR

I've been wanting to try this -

I run a couple of RTL-SDRs and use GQRX for general scanning and OP25 for P25 decoding and streaming to Broadcastify. It's a hobby related to what I do for work, and it keeps me sharp on a few fronts.

I like crowd source adsb aggregation and have helped a few people set up nodes but thought this was a cute use of adsb
https://skybot.cam/about. Think would be more interesting deployed in near airport environments.

I use rtlamr to pull in my gas meter data and rtl_433 to pull in temp and humidity sensor data. Home Assistant collects it all and then I have several dashboards in Grafana.

There were a few of those running in Ukraine at the start of the war and I was fascinated by watching the spectrum graphs of all the jamming going on.

Am sure dirtboxes were were very popular there

Sorry to bump such an old thread, but I just started playing around with a SDR. I got all the radio stuff (analog, digital, trunking) working pretty quickly, but I've been playing around with grabbing satellite images. Seems like I have terrible timing as the NOAA satellites just went offline, but I was able to pull these two images from two different weather satellites (Russian weather satellites). Pretty cool stuff.

No, but sounds cool

I did a deep dive into SDRs across Europe and Ukraine at the start of the war with Russia trying to figure out which bands Russia was jamming and when. Seems like a fun hobby.

pulling from GOES satellites is pretty dang cool!
