GNU Radio and APRS


I made modifications to the project   gr-APRS - A GNU Radio Block for Receiving APRS  at https://handiko.github.io/gr-APRS/
to work with GNU-Radio  on Ubuntu 22.04

Below are screenshots of the flow graph and output.  The PDU vector contents are visible lower left and AX.25 packet on bottom.

Note: A modification is needed to the software that converts from HDLC to AX.25 to avoid the error "Unexpected stop of address section"

The only file I modified was   gr-APRS/Examples/APRS_RX_RTL.grc

Well......  the   embedded  HDLC to AX.25    blocks  needs lots of work!
