I just received my OpenSpot3 yesterday shipping was super fast from Europe to the States.

Since setting up the OpenSpot I cant hear audio clearly. In the OpenSpot console it shows loss of >30% for each transmission received on REF001C. People report they hear me very clearly.

Seeing lots of invalid seqnum errors in the logs.

My connection is stable at 1gbps with a maximum throughput of 3.5gbps at my edge router and I have made sure to open all the necessary UDP ports to the openspot.

Below is an example log from DMR connector but its the same with d-star. I ahve tried with a LTE router Wi-Fi hotspot and get the same behavior so have ruled out my home network.

So far my troubleshooting steps have been:
Try different WAN connection Try different network router Try factory reset device and re-setup from scratch Upgraded to beta firmware
Not sure what else to try... my DVAP and RaspPi setup work flawlessly.... but don't have all the features of the OpenSpot.

Many thanks in advance... super excited to get this thing working.
