Hey Volker I understand there are ways to implement it using direwolf. I am more concern to solve this problem with GRC and mostly with its core.
Can you help me in figuring out the procedural steps to be taken to implement a receiver in GRC to decode a signal with G3RUH mode Ax25 and 2FSk Thanks and Regards Yugal Joshi On Wed, 12 Aug 2020, 3:30 pm Volker Schroer, <dl1...@gmx.de> wrote: > > The master branch is for gr3.9, but there is a gnuradio 3.8 branch > > Another good starting point for ax.25 could be wb2osz/direwolf on github. > — Volker > > > > Am 12.08.2020 um 06:31 schrieb Yugal Joshi <yugaljoshi2...@gmail.com>: > > > Hello Jeff > Thanks for replying > > From what I learned in last two days in GNU Radio, it looks like gr-25 is > an OOT module. > gr-25 works with GR 3.9 and pybinds and I am using GR 3.8.1.0. > > Also I want to implement G3RUH 2FSK AX25 using the core modules of GRC or > programming new OOTs so that I can improve my learning curve. > > Any help would be appreciated from the community. > > Thanks and Regards > > Yugal Joshi > > > On Wed, 12 Aug 2020, 4:45 am Jeff Long, <willco...@gmail.com> wrote: > >> Have you already take a look at this? >> https://github.com/dl1ksv/gr-ax25 >> >> On Tue, Aug 11, 2020 at 4:13 PM Yugal Joshi <yugaljoshi2...@gmail.com> >> wrote: >> >>> Hello all >>> I am new to the GNU Radio community. >>> I am starting an effort to implement a receiver using GNU Radio for the >>> amateur radio whose transmitter operates in G3RUH mode with 2-FSK >>> modulation and AX25 data format. >>> I designed the project to learn GNU Radio as well as to >>> contribute something to the SmallSat Community of my institution Indian >>> Institute of Space Science and Technology (IIST). >>> >>> Is anyone else working on the same configurations ? >>> >>> Anyone who can guide me through the procedural steps I should take to >>> design this receiver(G3RUH mode with 2-FSK and AX25 data format)? >>> >>> As a background information : >>> The AX.25 protocol is a standard for encoding the data that includes a >>> message header,station callsign, destination callsign, message and a simple >>> CRC-16. >>> The system is widely used for position reporting of the amateur stations >>> >>> Looking for a directive path to move ahead and a positive response. >>> >>> Thanks and Regards >>> -- >>> Yugal Joshi >>> B.
