Good Friday Sonde Hunt
Another great day for Sonde Recovery here in sunny California. The winds are good, the weather is nice and the sun is still up at landing time giving plenty of light. This Sonde was originally predicted to land near Rancho … Continue reading

Spring is nearing and so is the 2013 Sonde season. Landings are still in the dark so not too good for video or pictures but that will soon change. This is Sonde #4 (SN 7037645), it was launched from Oakland … Continue reading
Mobile Sonde Receiver & SDR
Another winter project! Mobile Sonde hunting is difficult enough without having to worry about the radio moving around in the back seat as one drives. In the past, my R8500’s power or IF would disconnect depending on how fast a … Continue reading

WX Sonde Received
In the USA there is apparently some use of WX Sonde in L-Band. Well, it’s confirmed now with this excellent signal from a sonde launched from Reno, NV. Dish was positioned at point that was predicted for ballon burst (the … Continue reading
