Now that the W1AAD DSTAR repeater is back on the air, there might be some interest in participating in (or listening to) the Raspberry Pi Net which meets on the 1st and 3rd Monday of the Month on Reflector 38C.
You can change the link over to 38C by keying your rig and pressing the “*38C” DTMF keys, or by adding a “REF038CL” to your UR list.
Please be aware that the repeater will automatically relink to Reflector 69C after 25 minutes of inactivity, or you could put it back there when you are done by sending “*69C” or using “REF069CL” from your UR list.
There is also a rather active Facebook Group called “Raspberry Pi Amateur Radio” with almost 3,000 users. https://www.facebook.com/groups/251260325054240/
