Hi ib, OZ1MY The accent of the interfering station on AO-51 is from Sardinia Island and the person speaking is a radioamateur discussing about a 50 ohm impedance with another Ham.
www.enduro.idl.pl/audio_sat/AO51_30_11_09_0754UTC.mp3 You cannot solve the problem existing as well in Spain shooting down all taxi drivers that are using 2 meters for their communications. The only cure is to make the LEO satellite receivers less sensitive and use more EIRP at the ground station.........no HT's my friend ! The above problem was not existing on HEO satellites like OSCAR-10 OSCAR-13 and AO40 because the EIRP necessary to access the transponder was almost 20 dB greater than the power radiated by a taxi driver or by the Sardinian station. The second cure don't sell a tranceiver covering the amateur band to everybody without an amateur licence is against the commercial purposes i.e. it is unviable. I know that you will complain with my statement and the Spanish autorities but if you don't like the Spanish or Sardinia interference over AO-27, AO-52 and SO-50 you must pull for only one HEO and not for many supersensitive LEO's 73" de i8CVS Domenico ----- Original Message ----- From: "OZ1MY" <oz...@privat.dk> To: <amsat-bb@amsat.org> Sent: Monday, November 30, 2009 5:05 PM Subject: [amsat-bb] Re: morning pass AO-51 > Hi Mateusz, > It sounds like Spanish to me.
