No, not a opera here. It's OPERA digimode. Really don't know what I'm talking about. But PA1SDB Peter asked if I could monitor the 630m band with OPERA. So I installed the software and it seems to be easy enough.
I managed to receive 5 stations in 24 hours. I guess it's just the popularity of this digimode. It's not as well known as WSPR. I might test it another time again. In the mean time I'm back on WSPR.
