installed my DV4mini on a Raspberry Pi linked to a TYT MD-380 radio this week and they seem to be working fine together. However, I hear very very little traffic, if any, from any reflectors, even when scanning via the DV4mini control panel. I do hear a "Connected to xxxx" announcement when I connect to some reflectors, which tells me I am linked up OK and the dongle and the radio are communicating. The dongle shows xmitting when I key the radio.
So, why am I not hearing any QSO's?
Question #2, What does the "Echo" icon on the DV4mini control panel do ?
OK, a third Question. What reflectors are generally the busiest?
