This is just a short little update to my post about tracking weather balloons. Last night I had an email from auto_rx about discovering a new balloon. No big deal nothing unusual here, I normally get anywhere from 3-5 of these a day between the 0Z and 12Z launches. When I looked at the details though, something caught my interest. The distance to this particular sonde was 467 km or 290 miles away! This surprises me seeing as my antenna is only about 9 feet or so off the ground. I'm planning an upgrade of sorts to this setup in the not to distant future. I'm hoping to set up a 10m mast and I plan to stick it at the top. Getting higher up in the air should let me detect the sondes when they're a little closer to the ground.
