I have a new OpenSPOT4 Pro that was working great through all modes using different radios until recently. Now it no longer consistently receives from my radios in any mode. I primarily use DSTAR with an Icom 705 and the OS4 seems to ignore the transmissions. I know it receives the transmission because it registers the signal on the RSSI graph when I key the radio, it just doesn't do anything with the signal. The green LED stays slow, it does not go to the fast blinking green to indicate the modem is transmitting my signal. Sometimes it will connect after holding PTT for a few seconds (longer than normal) and the Call Log registers my transmission but puts (late entry) in the log. Other times it works normally as expected but not very often.
The OS4 works just fine going the other direction, I can hear others making calls on the reflectors I am connected to with no issue. This setup worked perfectly for two months now it doesn't seem to be working and nothing has changed with the configuration that I can tell. I have attempted a full factory reset and the problem persists. Only thing that might be different is I believe the OS4 did a firmware update automatically in the last week. It show I am on firmware v80 that was "built" on January 9th 2025. My reading indicates this is a stable firmware but that appears to be the only thing that has changed recently.
Any help is greatly appreciated
