Hi Mateusz, It sounds like Spanish to me. I heard it during the pass also. In Spain some people use the 2 meter band for privat talk. They are not necessarily radio amateurs. It is an old story :-(
I tried to contact the Spanish authorities - but they do not do anything. It is often worse on the AO-27 uplink at 145.850 MHz. Sometimes they block SO-50 - but you can not hear it - however they make it drop out. 73 OZ1MY Ib ----- Original Message ----- From: "Mateusz" <sq7...@poczta.onet.pl> To: <amsat-bb@amsat.org> Sent: Monday, November 30, 2009 9:32 AM Subject: [amsat-bb] morning pass AO-51 > Hallo > > Today morning I recorded signals from AO51 downlink with my call and a > station in background: > www.enduro.idl.pl/audio_sat/AO51_30_11_09_0754UTC.mp3 > Elevation was 3 deg and lower. > Station heard in background probably doesn't know that transmits within > satellite part of 2m band, maybe it is not amateur? > > Matt SQ7DQX _______________________________________________ Sent via amsat...@amsat.org.
