There are some nice wide HRPT signals coming from NOAA 15, 18 and 19 (others too, but these are the ones I looked at today). NOAA 15, 18 and 19 are LEO satellites and therefore require real time tracking. Since it’s been a while since i have tracked any LEOs it took some time to get the tracking software operational, not to mention getting the dish calibrated. The signals are pretty good and stable for most of the 10-15 minute pass – suitable for decoding software.
Not a bad signal from NOAA 15 with it’s omni-directional antenna.
The signals coming from NOAA 18 and 19 are RHCP and look to be 665.4 kbit/s split phase PSK. I could not confirm this because of the government shutdown.
