fm_transmitter VS rtl-sdr-blog

To share a recent example, with just ~100mW of transmission power, they managed to fly an RC plane to a distance of 100km: https://www.youtube.com/watch?v=CYJ2UOrlXgM .(Their transmitter from the ground station was configured at a higher power, but the transmitter on the aircraft was transmitting telemetry back at 100mW throughout the distance)

Another related fun project is using raspberry pi gpio to work as an FM transmitter: https://github.com/markondej/fm_transmitter

The more in-depth way would be to build something yourself, based around a raspberry pi compute module or similar. You could then pick out all the hardware individually, and even include things like short-range radio comms. Putting it all together in a nice case and making all the software play nice would be quite a project though.

it's just a raspberry pi 3B with some software and a random ass radio lol

Clone this repo and build it. Follow it's instructions and find a tutorial (https://pimylifeup.com/raspberry-pi-pirate-radio/) if you need. https://github.com/markondej/fm_transmitter

I am currently following this guide https://github.com/markondej/fm_transmitter

You have to do a few more clicks for the link to the project.

here is the program i am using

as long as you have a fully updated raspberry pi with some form of raspbian, you can broadcast. You can find a lot of tutorials online, but the software I used can be found here: https://github.com/markondej/fm_transmitter

https://www.rtl-sdr.com/ is a good place to start for SDR articles, software and advise. Good luck.

I've reported it here: https://github.com/rtlsdrblog/rtl-sdr-blog/issues/18

Download the https://github.com/rtlsdrblog/rtl-sdr-blog or https://github.com/librtlsdr/librtlsdr version instead. Even try both, since there may be differences.

Take a look at the RTL-SDR, I have a Blog v3 and it's great.

This site has some great examples on what various inexpensive SDR hardware can be used for: https://www.rtl-sdr.com/. Use cases range from receiving weather satellite imagery, to reverse engineering radio protocols (e.g. for remote door openers). Several years ago I used an inexpensive DVB USB dongle containing the RTL2832U chip (which enables SDR), to sniff 2G/GSM broadcast packets.
