Hi Domenico, Thanks for the correction. It is not so often Italian radio amateurs that are the problem.
I too would like a HEO - in the meantime I will use whatever satellite we have :-)

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.

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

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.

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?
