We do all comms via satellite, including the current GPS location, no comms over VHF. I'm curious how you're tracking down a traditional radiosonde though, do you actively chase while it's in the air and then use visual reference as it comes down?
You can use the data collected from hobbyist ground stations and displayed at https://sondehub.org/ to track them while in the air.
I am not really into tracking radiosondes while they are in air. What I do, is like a radio "fox-hunting" when they come back on the surface, using a directive antenna.
