APRS weather via Tiny Track TT4
« on: December 24, 2016, 07:26:37 PM »
Hi, I am attempting to set up a remote weather station using a solar-powered setup.  The weather station is an old serial output WM918.  For testing, I'm sending it to a laptop running Weather Display, which is set to output to a TNC every minute.  The TNC I'm using is a Byonics Tiny Track TT4, which I was using for tracking, where it worked fine.  After a bit of fighting with old Windows software and a faulty serial port, I now have Weather Display processing the WM918 data and outputting an APRS packet.  The TinyTrak TT4 is accepting the packet and sending it to a handheld radio that transmits it OK, but when I look it up on, the packet is missing all the values.  All the information is there, it's identified as a weather station, but no values!  All the data type letters are there (T for Temp, B for barometric, etc) but followed by dots instead of numbers, as below:

Any suggestions?

My first thought would be to verify the Baud Rate of the serial port config.  I had some issues with that when I set my TT4 up.  It kept defaulting to something other then what I wanted.

I have a similar problem with twitter! Sometimes the data is there but sometimes not. I get emails to tell me the tweets are there but the data is missing but then when I open the emails to see twitter feed, the data is there. I tend to then go and forget about it!  (
