 These bands therefore have a much higher probability of carrying our signal candidate than the rest of the available RF spectrum, so let's target the usual ISM suspects first. In Europe 433 and 868 MHz are commonly used for remote controls (even cranes), data/sensor telemetry (weather stations and the like) and much more.  These bands therefore have a much higher probability of carrying our signal candidate than the rest of the available RF spectrum, so let's target the usual ISM suspects first.

-Let's pick 433 MHz, fire up osmocom_fft, gqrx, SDRangelove or any other SDR receiver with a spectrum analyzer/waterfall display tuned to 433 MHz. +Let's pick 433 MHz first, fire up osmocom_fft, gqrx, SDRangelove or any other SDR receiver with a spectrum analyzer/waterfall display tuned to 433 MHz.
