A couple of nights ago, I was reading a book with 50.125, the calling frequency for 6 meter sideband, on in the background, when all of the sudden, an Oliva digit signal came on the frequency. I'm assuming he was calling CQ and trying to generate some Oliva interest on 6 meters. He tried about three times and likely was sending a frequency up the band above 52.220 where I have copied other Oliva signals this season. Kind of interesting.
