Some improvements to the software over the last few days:
1) The way that the re-sync bits are generated has been changed. The entire frame is reformed to ensure that the re-sync pattern (0x55, 0x2d, 0x16) is sent every 21 frames, regardless of the incoming stream. This has eliminated mid-over beeps during G2 and D-Plus sourced QSOs. The same logic has been applied to local repeat which assists marginal incoming transmissions, and to outgoing G2/D-Plus packets.
2) The detection of a valid station on the input has been changed so that only valid D-Star headers will cause the repeater to open. FM/Squelch/Invalid-CRC headers will not open the local repeat functionality and are effectively ignored.
3) Lost sync on Internet-sourced packets. This is a difficult one to crack, but I can now detect and compensate for up to 2 seconds of lost DV frames, in-filling with silence.
