I have a friend who chases the sondes he use that and link. I went with him one and we located one in back yard of a Virginia residence. The fellow was sure what it was when he saw it in his back yard. My friend educated him on what they were doing!

Speaking of Sondes....Here's a link to current radiosonde weather balloon
ops worldwide. They are at-altitude at 0000Z and 1200Z daily. They
actually launch about 45-60 minutes before that. Major airports are the
usual launch sites.
The ones out west here are RS41's that operate at 404 MHz, around 60 mw and
I can receive the basic telemetry from a LONG distance away. Click on your
local balloon and it shows all the data including its GPS coord's, current
altitude, temp etc.
Plot shows the track and predicted future track. They usually get up to
around 100,000' AMSL, often higher before they burst. Then a long ride
down on a parachute. (fun fact: from 105,000' the parachute has NO
initial effect on the fall rate...very little air up there... LOL)
