This is what I have tested
The dongle works with FM radio so dongle good
Tested VAC Output on DSD+ lvl= 68%
Change SDR to known 800mhz Channel and it shows signal
DSD+ does not scroll like youtube videos I have watched it just sits there
Not sure what else to do
What type of transmission are you monitoring? P25 ? DMR ? NXDN ? Provoice ?
