I'm assuming your using the right digi path, ariss? Also what might be happening is what WB4APR called the donut-hole effect, See...

Good Morning! I need to pick the corporate brain. I cannot access the ISS digi. I copy digital broadcasts form the ISS --- AOS to LOS. But not mine. This is my setup: W10 - UISS - SoundModem - SignaLink - FT-847 (1200 packet ). Computer control: W10 - SatPc32ISS - FT-847 (Split mode) for some reason SatPc32ISS only controls the downlink Frequency, so I have the uplink set at 145.825 Mhz. I have even tried trimming the uplink to agree with SatPc32ISS's uplink. I have tried different TX audio levels from barely triggering the SignaLink's VOX to very high. I believe that I have UISS setup properly, My TX packet format looks like everyone else's. NO SUCCESS!!
When I transmit a local SatGate picks up my packets and successfully sends them to aprs.fi and I show up in a few seconds on aprs.fi.
I have used W10 - WinLink Express - SoundModem - SignaLink - Ft-847 to use the WinLink system.
I have used W10 - Packet Engine Pro/Uiview32 - SignaLink - Ft-847 to use the local APRS sytsem.
A last moment thought: Is power a factor, would too much power complicate things ? I do not recall trying different power levels. My TX setup is FT-847 (Max power 50 w) - M2 14 element X- yagi - Yaesu 5500. Oh, by the way. No success with NO-84, even when I hear it. But it is nopt operational often.
So, folks, any ideas ?? Thank you, have a good day and stay safe, Covid free, 73
