Hi John, KD6OZH

Just for record i have included belowe a list of  OSCAR-13
operators with their call letters and antennas used for downlink
Mode-S from 2400.711 to 2400.747 MHz during the lifetime
of this glourious  U/S transponder
 
The power of OSCAR-13  mode-S was only 1,5 W pep and the 
satellite antenna was an helix with G=10 dBi and so EIRP=15 W 
pep

In comparison the power of the S1 TX  on AO40 was 50 W
pep and the antenna was an helix with G=10 dBi and so 
EIRP=500 W pep
The power of the next P3E will be 38 watt pep with a similar
antenna.  

The mode-S transponder of OSCAR-13 was "hard limited",in
other words no AGC was in it and so the 1,5 W pep
available for all users was proportional to the uplink power.

At epoch time of this list,uptodate by W4FJ on 14 jan 1994 
it was very difficult if not impossible to find ready to operate 
preamplifiers/converters antennas/antenna feeds for 2.4 GHz 
and the most part of  the equipments  where necessarily hombrew 
by amateurs.

In addition,at that time about 12 years ago,the best GaAsFET 
available at amateur price showed a noise figure not less than 
1 dB at 2400 MHz

Even though the list of users is very long.

Please read it
