<div dir="ltr">Looking at that log, it looks like you're getting two lots of telemetry data coming into chasemapper, arriving just after each other. (i.e. 13:59:33,236, then 13:59:33:466). The behaviour you are seeing is 100% expected - it's saying that there is no difference in time between the incoming data samples, and therefore it cannot calculate an ascent rate (altitude_delta / time_delta).<div><br><div>Do you have two copies of auto_rx running on the network where chasemapper is running? If so you should disable the horus_udp output on one of them. </div></div><div><br></div><div>Cheers,</div><div>Mark</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Apr 20, 2019 at 8:13 AM Steve via Vk5-wx-sonde <<a href="mailto:vk5-wx-sonde@vk5fo.com">vk5-wx-sonde@vk5fo.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><u></u>
