Hello all; for information here in south west Europe we use 2320,100 to 2320,300 cw/ssb portion
of 13cm band for tropospheric , AS , RS,  traffic. I have been told by Piero
I5CTE there is permanent continuous carrier beacon around 2320.190 MHz (+/- doppler) by 1 of
the 3 Sirius elliptic NA satellites. It appears reception is very good here with small 10 turn helix
antenna (in spite of 12m heliax coax) peaking 539. Apogee (50000km ) around 325°
with 27° elevation. F5BOF reports same signal with small hand held 25 elements f9ft yagi.
So these are for us very interesting beacons. Depending hours we can receive 1 o 2 sats.
Real time positions (Sirius-1 / Sirius-2 / Sirius-3) here:
Any info about beacon sat polarisation and eirp ?
