Observation 246330: NOAA 18 (28654)

Regarding Observation 246330 and others observations I get from HRPT, why I never see data in the waterfall that look like HRPT transmission, but always something like a beacon ?
What can explain this ? Maybe they don’t transmit above my GS ?

I tried to find correct observation of HRPT transmission in the network, but It’s hard to search by a transmitter. (I tried with API and give up)

Do you have any ideas ?

< cgbsat[m]> jujun: concerning your HRPT question on the forums; HRPT is much broader than the band your sampling, so you only see the carrier
