Amateur Radio Uses for the Raspberry + Raspberry Pi Ham Radio

Amateur Radio Uses for the Raspberry + Raspberry Pi Ham Radio

The purpose of this article is to show you what can already be achieved and give you some ideas, rather than detail how to achieve each use! I’ve provided links against each use to help you take the next steps. Hopefully this article will encourage you to get started with the Pi.

I have built and running an ADS-B ground station for CDN$150 / USD$120 FlightAware has easy instructions that walk you through the purchasing, assembly, and setup of a PiAware ADS-B receiver. It takes about two hours to setup your own ADS-B ground station and track flights in real-time.

Raspberry Pi powered ground station using Software Defined Radio(SDR) to receive ADS-B messages directly from commercial flights and publish MQTT messages to IBM IoT Platform.

BUILDING A HOMEMADE FM REPEATER WITH A RASPBERRY PI, RPITX AND RTL-SDR DONGLE

BUILDING A HOMEMADE FM REPEATER WITH A RASPBERRY PI, RPITX AND RTL-SDR DONGLE

A radio repeater is usually a radio tower that receives weak signals from handheld, desktop or other radio, and rebroadcasts the same signal at a higher power over a wide area at a different frequency. This allows communications to be extended over a much greater area.

Repeaters are generally made from expensive professional grade radio equipment, however ZR6AIC has been experimenting with creating an ultra low cost repeater out of a RTL-SDR and Raspberry Pi. In his system the RTL-SDR dongle is set up to receive a signal on the 70 cm (420 – 450 MHz) amateur radio band, and then retransmit it using Rpitx on the 2M (144 – 148 MHz) amateur radio band. He also adds a 2M low pass filter to the output of the Raspberry Pi to keep the signal clean.

Testing of a radio link / radio bridge rtl sdr at low cost. Using an FM transmitter to resend various digital modulations and using RTL SDR with SDRTouch for reception. SSTV decoding with Robot36 and VOA decoding with Tivar. Android device used is a One Plus One.

you can best the receiving technique with minor modifications and devices, the use of an audio adapter for the mobile phone in order to split the microphone and headphones in order to reinsert the sound from the headphone into the microphone (note that an additional modification might be required with resistances to overcome audio bug due to various Android OS smartphone or various versions or standard audio)

Amateur Radio Power for your Raspberry Pi

Pi-Go – Amateur Radio Power for your Raspberry Pi | QRZ Now – Amateur Radio News

Nearly all Amateur Radio equipment runs off of a 12V supply, well, anywhere from 10-16V depending on the source. Wouldn’t it be nice if the Pi could also run from that same source? That’s where I designed the the perfect topping for your Pi… no, not a scoop of ice cream, but what I’ve called the “Pi-Go”. Now you can include your Raspberry Pi in your Go-Kit and power it from the same source as your radios.”

Review of my Allstar node

This video shows the G7RPG Allstar micro-node. If anyone is interested in Allstar but has no idea how to build a node or what to do,then watch this video,as it explains what’s in the node and what you need to do to build one. Peter does a fantastic job and makes a high end product. These are way cheaper than other ready made products.

Building A Raspberry Pi-3 Portable AllStar Node

Building A Raspberry Pi-3 Portable AllStar Node

A Portable Allstar Node – means never having to be near a Repeater to use it.  Allstar uses the Internet – to connect to a distant Allstar Node – that is connected to the Repeater System you’re trying to reach.  Portable Allstar means you use a WiFi Hotspot in your Car or RV that provides the WiFi connection for your Raspberry Pi 3 computer – that runs the (free) Allstar software.

Raspberry Pi ADS-B Receiver: Build a Live Flight Tracker

In this tutorial I will take you through the steps to build your very own Raspberry Pi ADS-B receiver. This is probably more commonly known as a flight tracker as it has the ability to track flights within a 100-300-mile radius.

This setup does require an extra piece of equipment in order to work so I have listed all the required pieces of equipment below.  Take extra note of the TV dongle.

Raspberry Pi
4 GB SD Card (8 GB+ Recommended) or Micro SD Card if you’re using a Raspberry Pi 2 or B+
Ethernet Cord or Wifi dongle
Power Adapter
Mini DVB-T Digital TV USB Dongle

The software we use in this Raspberry Pi ADS-B receiver tutorial is supplied by flightaware. It is really simple to install and allows you start collecting that data in no time at all.

Probably the most complicated part of this tutorial is linking your Pi to flightaware. Sometimes it will be really easy and pick up the ADS-B receiver in no time other times it will take a while or manually need to be done.

It is important to note that if you setup a flight tracker and supply the data to flightaware they will upgrade your account to enterprise. An enterprise account is worth $90 bucks a month so you will make you money back in no time if you’re looking at just getting that account upgrade.

Replay Attacks at 433 MHz with RTL-SDR and a Raspberry Pi running RPiTX

Showing how to perform a simple record and replay attack on 433 MHz ISM band devices using nothing more than an RTL-SDR and Raspberry Pi. The Raspberry Pi runs RPiTX which allows it to transmit from a GPIO port with just a wire attached. No extra transmitter hardware is required.

hamvoip version 1.5 is now the only Pi download on this site. All previous Pi versions have been deprecated and users are encouraged to update to the 1.5 version. The 1.5 version updates online after installation and a user can update manually whenever a future update is announced. Several additions have been added by online updates in the last few months including -

Supermon a much updated Allmon2.
AutoSky a Skywarn program for weather alerts on your node.
Timer code has been updated and is now accurate. Timers were never accurate in Allstar code prior to this!
The weather condition and temperature have been added to the time routine.
DTMF pass through has been simplified and now works.
A problem in the wireless code has been corrected.
A CPU turbo mode script has been added.
