Open IP over VHF/UHF #PiDay #Radio #RaspberryPi @Raspberry_Pi

The Rowetel blog discusses sending Internet Protocol (IP) traffic over VHF and UHF radio frequencies.

My initial goal for this work is a “100 kbit/s IP link” for VHF/UHF using Codec 2 modems and SDR. One application is moving Ham Radio data past the 1995-era “9600 bits/s data port” paradigm to real time IP.

I’m also interested in IP over TV Whitespace (spare VHF/UHF spectrum) for emergency and developing world applications. I’m a judge for developing world IT grants and the “last 100km” problem comes up again and again. This solution requires just a Raspberry Pi and RTLSDR. At these frequencies antennas could be simply fabricated from wire (cut for the frequency of operation), and soldered directly to the Pi.

See the article here and the GitHub repo for this project.



Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
