RTL-SDR V.3 Frequency Range?

Post by bab5871 » Sun Nov 25, 2018 3:32 pm

Will the current production v.3 dongle be able to receive NOAA 16 on 1694MHz? I seem to be able to pick up local beacons on 1296MHz, but I can't seem to hear anything from NOAA 16 up that far in frequency. There are published ranges... (Frequency Range: 500 kHz – 1766 MHz) but I'm not able to hear anything at all way up there. Suggestions? Could it be a bad dongle? Or are there other recommended ones for that range?

Yes it should be able to receive those frequencies.

What type of antenna and LNA do you have? Remember that these are weak signals, so you need a good tracking directional antenna, and a good LNA to reduce the system noise figure, otherwise you'll certainly hear nothing.

Using a 24db gain dish, no tracking needed for geostationary. I hear absolutely nothing even with the SAWBird+ LNA.

But NOAA 16 isn't geostationary, it's polar orbiting, and needs tracking.

You might be thinking about the GOES satellites which are geostationary, you need to point at them fairly accurately. Even a few degrees out and you could receive nothing at all.

Which SAWBird do you actually have? The 1688 MHz center one?

Also what is the dish, and do you have the correct modified feed?
