      Hello All,

      I have been trying to get my Wx station working through the new OT3m. I have installed the Weatherlink 6540 for APRS unit inside the display, used the supplied Serial port adapter(blue 9 pin adapter to phone line looking plug), and verified it works with the windows Weatherlink software.

      Myquestion is how to get it to send data out the OT3m in a stable manner? I have the OT3m setup as "text" at the same baud rate the Davis display unit is set for. When I power up the system it runs ok sending out one report fine, but ALL other reports is just blank data (no wx data on the sent packet). I am thinking the streaming data from the wx station is out of sync with the OT3m?

      Right now, the streaming config in the Davis unit is set for 5 sec timeout, 4800 baud, and transmission every 1 min. The OT3m is set to transmit every 5 mins. (thinking if the Davis unit sends out data more often a better chance for the OT3m to capture it. Same issue happens when they are both set for 5 mins Tx report time)

      Example here of what I see.
