PositionlessWeatherReport(byte[] body,

java.lang.String tp,
AX25Callsign dst,
long rcvTimestamp)
Standard constructor for PositionlessWeatherReport, for decoding from an AX.25 frame (or equivalent). |
|
PositionlessWeatherReport(long now)
Alternate constructor, used to create an empty message for population by local weather data. |
|
PositionlessWeatherReport(java.lang.String body,
int offset)
Alternate constructor, used only to decode $PKWDWXI special message from Kenwood TH-D72 HT's built-in TNC when weather data is expected to be imported into the TNC from a local weather station. |
