Title: NRSC5 Reception and Remote Control with GR-NRSC5, GNU Radio, HackRF, and RTLSDR V4
In this video, I explore NRSC5 reception and remote cellular control using GR-NRSC5, GNU Radio, HackRF, and ...the RTLSDR. Why you ask? I just wanted to talk about several different things and this seemed to be a logical and interesting way to tie it all together.
SIM7600A Cellular HAT Setup: https://github.com/alphafox02/simcom_wwan-setup
NRSC5 Application: https://github.com/theori-io/nrsc5
NRSC5 GUI: https://github.com/cmnybo/nrsc5-gui
I start with building the applications and also setting up the SIM7600A Cellular HAT. I start off connected to the NUC via Ethernet and VNC from my desktop, but by the end I'm connected w/ cell service and SSH thanks to a renew of my extra Tmobile prepaid SIM card laying around.
We'll delve into the essentials, including the NRSC5 RTLSDR application and the NRSC5 GUI, crucial components for our mission. While I initially aim to use an EPIC SDR on the remote NUC, we'll pivot to the HackRF by Great Scott Gadgets along the way.
Once the hardware is sorted, we'll create a functional flow graph and validate it with SigDigger and the RTLSDR v4 to ensure the NRSC5 signal is visible in the spectrum.
I'll demonstrate how to run the NRSC5 application with the GUI and the RTLSDR v4 on my desktop. Through SSH, I'll initiate the NRSC5 transmitting flow graph on the Intel Nuc, followed by confirmation of successful reception and decoding of NRSC5 back on my desktop.
Lastly, I'll introduce a Python script from the GR-NRSC5 repository, allowing me to easily push album art from my desktop to the remote Intel Nuc. Thanks to TailScale and the Internet, the Intel NUC receives this data using the cellular HAT, subsequently altering the album art on my desktop.
