AO-40 S2 MB report 2000-12-05



	Hi all,
To all S-banders,

Location: JN88DF, Vienna, Austria
Equipement: 1.2m dish, 2.5 turn helix, preamp, 10m H2000, IC-970

phase  distance  squint  S-meter
 16    15000 km    30°     8
 24    18000 km    40°   0 - 6

Copy of telemetry with DSP-12 acceptable (some 20% CRC errors), 
with G3RUH demod - due to the narrower PLLs - marginal (around 50%).
The magnetorquer was in operation (and the cause of the frequency
jitter).
Frequency of S2 middle beacon: 2401.331 MHz
Useable TLEs:
AO-40                   
1 26609U 00072B   00329.17985884 -.00000509  00000-0  00000+0 0    69
2 26609   6.4136 245.1181 7345577 180.9898 176.0209  2.03019174   167
STRV 1C
1 26610U 00072C   00337.02909023 -.00000077  00000-0  00000+0 0    98
2 26610   6.3783 242.3238 7347480 186.3603 152.6817  2.03015472   327

Both TLEs yield AOS/LOS timings within one minute. Mean motion seems
to be correct to 5 digits.

Great signal - I have to get an attenuator for smaller squint angles ;-)
