Range Testing Meshtastic Nodes (Point to Point)...
Here I walk around town and send messages to a client inside of my apartment. I have separated these nodes from any peers/mesh so we only have a point-to-point system.
I find a maximum non-LOS range of around 1.2miles!

Using AI to monitor police radio for me... (Citizen style App)
Просмотров 3,5 тыс.8 месяцев назад
In this video, I show how I've taken my SDR-Pi police scanner from audible to textual with AWS Transcribe. The quality is not great yet, but I plan to improve it over time and eventually make something similar to Citizen at a smaller scale. The reference code is here: github.com/awslabs/amazon-transcribe-streaming-sdk/blob/develop/examples/simple_file.py

Building a $600 P25 Police Scanner for $250!!! (SDR-Pi)
Просмотров 19 тыс.9 месяцев назад
Here is my latest weekend project; a Raspberry Pi 5 with an RTL-SDR dongle running SDRTrunk software. It is configured to listen to the local LAPD channels and runs great! The chip gets a bit hot so I think I need to add a fan.

    I think my comment was deleted because I included a link but if you're having audio issues where a talkgroup shows up in sdrtrunks left or right audio channel but you have no audio from the speakers you can fix it temporarily by going to user preferences and changing the audio to mono then back to stereo. A better fix is to switch to pipewire instead of pulseaudio. Unfortunately I can't link the guide I used to switch to pipewire and remove pulseaudio and there are a bunch of guides that didn't work for me until I found the one that worked but it's from a website with baeldung as the name.

    Awesome news. I'm trying to build a PI5 head or headless (head [monitor] would be better for watching it) system that will SDRtrunk and then forward that audio to the input on a discord channel. I've seen Discord is available now for Pi, you answered the SDRtrunk portion, BUT, what could we use instead of Virtual Audio Cable (my windoze machines use this) to redirect the audio? Also will this setup handle 2 SDR's (CC+3VC)?

    • @rashnetproductions

      There is a guide on reddit in the discord subreddit to stream audio using pipewire to discord.

    Very Cool little setup! One thing to know is for a Large busy system u will probably need 2 maybe 3 Rtl-Sdr dongles to Cover it. You will miss half the calls with just 1 Sdr alot of the time.

    Going to build exactly this system but most likely will run 2x RTL-SDR instead of 1. Thanks so much for your video ive been wanting to get into this hobby live in los angeles but didnt want to spend the 600+$ for an SDS100/200 and i think this will work out perfectly for me and be much more fun.

    I created a similar system with Faster Whisper on github. It can run completely locally on even a raspberry pi and depending on your computer specs, it is pretty damn accurate and fast for speech to text. I then use OpenAI LLM for the sentiment analysis portion which builds a daily report which my program then emails to me.

    My only issue so far is the screen doesn't allow to see all of the options, once you're inside sdrtrunk. Trying to come up with a solution. Otherwise, everything is working great! Thank you!!! Edit: I hooked my Pi up to a computer monitor and was able to resize the windows there and set up sdrtrunk how I needed, then moved back to the touch screen.

    Hi, I would love to help contribute to the development, and also to satisfy the needs that I have. I want to do this with the police scanner app, or scanning website. I like that you are using the RTL SDR dongles, but even with giant antennas, my basement apartment blocks almost all signals, even right next to a window. I pick up very staticy analog audio, and digital audio streams never pick up. If I can get an antenna outside, then I could make a setup similar to what you have, and decode additional talk groups to watch for things of interest, but since I rent, I really doubt that will happen. So my idea is, run the police scanner app / website in the background, that handles the police audio, then have the program constantly transcribing all the traffic, by saving 1 min audio files, of course there's going to be a small delay, but that's okay. I also want it to show on screen like you have, send me an alert for things that match my criteria, through something like MS Teams or Slack, which I know how to do. Then, additionally, play an aubile chime or message. That chime could just be a notification sound from that Slack/Teams channel or through Home Assistant which plays on my Google Homes. The reason why I want to do this is because I've been swatted quite a bit. It's not like I'm super popular or celebrity or anything, but I'm well known enough in my area and in my town, that I've been swatted several times, including a former employee who continues to try to call the police on me. I've been interested in this idea for quite some time, and I periodically search for police radio transcription options. There was another project I found that also used the Amazon library and one that used a Google library.

    Hi, Top DNG. I was wondering if your SDR-Pi was still working well. Mine was working very well for a couple of months and then last weekend suddenly it just went quiet. No control channel showing, and of course, no audio. Some folks from the SDRTrunk Facebook seemed to think it was the geomagnetic storms and to give it a couple of days to clear. Well, that was more than a week ago, and no improvement. I'm curious to know if you're having any issues?? Thanks. ~Frank

    The texts on screen are so small, it can't be read. The attention is too long on the same computer screen. Maybe shorten this up, take the boring parts out of it. Show a talking head in stead of text that can't be read. Add a puppy or a smiling baby or lower yourself and make a dance before the camera.

    You have my undivided attention. I've been contemplating making something like this for a while and your video gets me motivated. I would love to use a smaller display to match the foot print of the Rasp Pi. Is that a touchscreen with USB cable back to the Pi? or does that pop up go away on its own as the software loads right before you hear the dispatcher talking?
