Hello all! I designed in 2018 the DMR-C4FM relay from Albi (Tarn), F5ZLH it works… Well, not that good, because we noticed a poor signal quality:
with the constellation, on a portable equipment such as the Rpi 4. we will beable to adjust the relay settings And there only GNURadio is installed correctly and worked perfectly with an RTL-SDR key. But most of the flow chart examples use logical signal sources and if some of them have an RTL-SDR key as input, they are either incomplete or with errors (wonder if this is not done expressly?) . And above all, no script linked to the flow chart concerned. So, I can only turn to the competence of your team to finally have this script validated.
Configuration is simple: SDR-RTL → constellation With thanks for help Mike -- Michel SLEPOUKHA F5ZZ (FR5FI - TU2DD - 6W8IY) F5ZZ-10 JN13AV
