Hola Roland,
Lots of trial and error to decode even a few GXIBA-1 frames here, as signals RX were weak. But, had recorded an IQ file using GNURadio. Looked for and exported the strongest frames using Inspectrum. Then, converted the IQ snippet to a wav file format using SOX. Under Windows, replayed that snippet (IQ) wav format file in SDR Console. FM wide demodulation. By carefully adjusting the frequency and bandwidth, got decodes using UZ7HO 1KUNS (AX100 Mode 5) soundmodem. See https://x.com/n6rfm/status/2019588630906564869?s=20
Good Hunting,
