ADS-B flight tracker with your Raspberry 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.
