I have a DV Mega dual band board on a pi 2B using an Icon 51A+ that has been working perfectly for over a year. I use a Verizon Jetpack as my only internet source. The only thing that has changed is I now have a static ip address with my Jetpack connection to Verizon.
The quality of my DStar transmissions has gone down to virtually unreadable according to my contacts. This has been on REF30C and various times over many days. All Echo tests I have done sound fine. I also can not connect to DCS024F which I used to use a lot.
Thinking corrupted SD card, I formatted a new card, downloaded the latest image (yes the correct one for the DVMega) and reloaded on the new SD card. I have exactly the same problems. Bad audio and no connect to DCS024F.
Update: The new downloaded DStar Commander file and the reinstall on a newly formatted sd card worked for the REF030C problem, but I still can not connect to DCS024F. I receive the "Linking to" reply, but no link ever happens.
