One of the SDRplay user community, Jukka, has started an interesting discussion on what he has called ‘propagation-triggered recording’ – he outlines the concept, and what he is doing, on our forum – see http://www.sdrplay.com/community/viewtopic.php?f=9&t=1839
The idea is that you monitor signals to determine if conditions are particularly good and can thereby trigger an I/Q recording of a whole band during that particular propagation high point – feel free to chip in with your ideas and to help shape what Jukka is doing.
Maybe CW decoding of amateur radio prefixes can yield a useful alert when signals from certain countries surface through the noise? There’s probably a lot of other practical opportunities for content-based triggering or even content-based tuning – especially if other factors are blended in – weather, time, stress detection in voices, popular twittersphere topics… where might all this end?!!!
