You are correct in your assessment. If a position
report is sent followed by the weather beacon, it is possible for some
digipeaters to act on the initial position report and digipeat that packet while
trampling on the weather beacon that follows. Thus, the weather beacon may not
be heard because the digipeater is passing the initial position packet and not
able to hear the subsequent weather beacon.
Jason: The weather packet contains position, so it
is redundant for a position report to precede a weather beacon that
contains position information. That is how it is coded in
There are 8 weather stations with T2-135 units
installed in Lawrence County, Alabama that exhibit some anomalies with a Peat
Brothers Weather station attached. The position report that is sent prior to the
weather beacon is not necessary and simply adds extra traffic to the network.
The second issue which is much bigger that the previous is the occasional
corruption of weather data that is transmitted. I have attempted to help the
Lawrence County group, but my time is has been severely limited with constant
Scott provided an additional program to load that
did not seem to help their issue with corrupted data. I have been unable to get
back with him to report those results. One of the weather stations that had been
connected to a UIDIG TNC worked flawlessly for many years until it was replaced
with a T2-135 and the corrupted data started at that point. We know the weather
station in this case was reliable, but all 8 weather systems exhibit the same
issue. Some more often than others. My hunch is it has more to do with the
voltage levels on the serial port that we hope to prove or disprove in the next
step. I ran an experiment emulating data captured from a weather station on one
of the systems that mis-behave most often and found that RS-232 levels from my
desktop transmitting at 10 second intervals for 24 hours showed no corruption of

It sends out a position beacon and then the weather with position one
second or less after that. Clogs or gets lost in the network at times and some
digis will not send the weather beacon along the network.

different beacons? Weather should have a position, too.
