Satellite Monitoring with SDR
If I may ask if any members are using SDRPlay as monitoring for downlink signals? If so, what software is your preference or suggestions?
I own a SDRPlAYdx and getting it out of mothballs.

Gerald,
I'll respond to the BB, since, this is... kinda good conversation for the BB. I have my RSPDuo hooked up to a broadband discone at roughly 20ft. I have an RSPDuo (and a couple other SDRs, funcube prov1.1, nooelect e4000 and a dvb-t stick), but I have dedicated the discone to this SDRduo. The SDRuno software it comes with is what I use. You can route the output (see RX settings) to any WME output device, which makes it uber easy to interface other devices with it, or you can write your own code to process the output, pipe it to the internet, etc... If you know c/c++, there's also an api you can use to control the RSP. This makes it easy to control the SDRPlay with Python / C#, etc... You can also easily interface the software with signalink USB. Oh, and the software is super easy to use, my two kids (9 and 11) can set the tuning frequency and tune around with it.
I will say, the SDRUno software does have some kinks to work out. The biggest annoyance to me is that I come and go from my home office regularly, and like to turn devices off or put them to sleep. When SDRUno is up and running and you put your machine to sleep, if you try to come back, it doesn't re-enumerate / connect to the device... You have to kill / restart it. Which is, kindof a pain. Also, the scanner is somewhat primitive and could use some more options.
Side note, you should also be able to download the RSP-spectrum analyzer, which is also neat.
You're welcome to contact me off the list anytime to discuss.

Hi, I have an RSP2 that I connect up to an Arrow Yagi for 2m -70 cm amateur reception and a homebrew LHCP L band helix for LEO/MEO SAR downlink reception ( Via a couple of switches and LNAs). I like it and SDRUno a lot. PST Rotator and Com0CoM can be used for doppler compensation ( K3RRR has a nice YouTube video on this). I'm sure there are other good approaches too. Alan VE2NHR

I’ll third the comments by Joe and Alan. I have the RSPdx and have used it in numerous ways. At the moment it is part of my combined station and get a fair amount of use for monitoring band activity. I use a discone as well... as a dedicated V/UHF antenna on one input and through an SDR switch on HF. Very versatile with SDRuno.

Hi,
I use SDRConsole with an SDRPlay 2, it has satellite tracking, doppler shift & NOVA compatible rotator DDE built in as well as remote control / doppler for an external TRX - all from a single bit of software.
I use this with PSTRotator to control the rotator, I have a pair of Wimo Xquads , feed from each band connected to a switch - from one side of each switch I feed a 2m/70cms diplexer that feeds my SDR - the other side of the switches usually gives 2m/70cms to Kenwood TS-2000, or sometimes via another 2m/70cms diplexer into my Yeasu FT-991.
This gives me the best of both worlds - it allows me to receive both 2m/70cms downlinks straight into the SDR and can use a 'stereomix' 'input' to feed audio from the SDR into telemetry decoding software, it also allows me to transmit via VHF / UHF up to the bird.
I do lose a bit of sensitivity with the diplexers, but on the plus side this does give a good amount of cross band isolation - just need to remember to make sure you have the switches in the correct 'direction' for the operations you want.
It's a great solution for being able to see your uplink on the waterfall and tune to other stations, but there is a bit of delay converted the SDR IQ into audio, so this can be a bit disconcerting until you get used to it.
I didn't really get on with SDRUno, but have been a very happy user of SDRConsole since it was first created.
