Observation 13859394: NOAA-2 (6235)

Regarding Observation 13859394 … hello everyone I wanted to ask why am I receiving very bad noisy signal and no data received my setup is a dipole antenna and a raspberry pi 5. Thank you :folded_hands:

from metadata, seen your sdr gain is not set.

try increase this value like:
SATNOGS_RF_GAIN=49.6

SATNOGS_RX_SAMP_RATE=2.048e6

and restart

And do not be to disappointed if still no data shows up, APT transmissions are disabled on the satellites.

These are all the support gain value when using a RTL-SDR

Don’t use 49.6 because that will also get you the highest noise level. Use a SDR program like SDR++, SDR#, GQRX and try to find the highest value where the noise increase is at its minimum.

Without an LNA start around 36.4

Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6
