The Italian right-wing Catholic fundamentalist station Radio Luce just switched on a new transmitter in the Bologna area on 756 kHz. The station gives only one identification announcement at the beginning of their daily transmissions at 0700 CET (0600 UTC). At that time the frequency is completely obliterated by Radio Romania’s 200 kW signal, so I had to use the decorrelation function of my Microtelecom Perseus22 SDR receiver connected to two orthogonal Wellbrook ALA-1530 wideband active loops to remove the interference.
At the beginning of this video (https://www.youtube.com/watch?v=cX-z0efqsmc) you can hear Radio Romania; at 0:20 I switch decorrelation on, which wipes out Romania entirely. Station ID is at 5:10, followed by time signal. At 7:15 I switch decorrelation on and off a couple of times, just to highlight its wow effect.
In this case I used automatic decorrelation; sometimes it works better than manual mode, other times not: you’ve got to try and see. Of course the result isn’t as good as in this case, your mileage may vary. But if you’re asking yourself whether decorrelation can eliminate your local pest and let you hear a weaker station usually impossible to receive, the answer, at least at times, is yes.
Received on 6 November 2026 at 0600 UTC in Forlì, Italy, about 60 km from the station.
