April 13, 2018 Nexmon SDR: Using the WiFi Chip on a Raspberry Pi 3B+ as a TX Capable SDR. Getting OP25 running in Ubuntu through a VM running on VMWare Workstation. The new version will run nicely on a Raspberry Pi 3, and probably on an RPi 2 as well. I used the new rx. Installing GNURADIO on 'Raspberry pi 3' CPU incompatibality solved( send QPSK signal as an example). However, some Pi owners claim it's possible to deploy apps. The next steps involve setting up OP25 for the particular system in your area, which mostly involves just editing a spreadsheet to input frequency data from radioreference. You could get dropped audio, crashes, etc. Airspy HF+ and Gqrx running on Raspberry Pi Tudor Vedeanu has posted a nice video showing the Airspy HF+ and Gqrx running on the Raspberry Pi 3 and using what appears to be a 7 inch touch screen. Filed under. I am in the process of making a scanner using a Raspberry Pi with OP25 on it. I got a program, OP25 working today on a Pi 3B+ using the RTL-SDR. Unless you live in complete darkness, you should know that RTL is a chipset originally designed for a USB digital TV tuner dongle. There’s more info on their wiki, too.
