Hi Erik,
it is expected that clients of the WSJT-X UDP protocol send a "Replay"
message (type 7) when they first detect a WSJT-X instance, as well as
forcing to the WSJT-X instance to relay all decodes up to that point (as
"Decode" type 2, or WSPRDecode type 10 messages), that have not been
erased, with an "New" field set to false, a "Status" message (type 1)
will follow. From that point the receiver should track further "Status"
messages to stay in sync with the band and frequency set in that WSJT-X
instance.
Note that there are edge cases where WSJT-X has no idea what band a
decode was transmitted on due to the nature of block codes when the
frequency/band changes mid receipt of the message.
