Latest wx ballon heatmap


last night I did a new heatmap with RTL_POWER. The frequency range is 404MHz to 406MHz. Intervall 30 seconds and binsize is 2000Hz.

I wanted to know which wx balloon signals are available at my place.

This is the result of 13,5 hours recording.

I caught seven balloons on five different frequencies in wx balloon band. Next time I will try to decode them with Sondemonitor by COAA.
