Thread-topic: [CRTech] SDRs in broadcast
We use sdr# at work to monitor our uplink. It lets us see our carrier relative to adjacent ones. We still check with the satellite people for accurate power setting but its a good monitor. 
I use SDR Touch on my android. It has rds. It's handy for quick checks. I'll dig out the real spectrum analyzer when I need to.
At home I use gqrx. It has rds too.

Sent from my Samsung Galaxy Express™, an AT&T LTE smartphone

The software determines RDS capability more then the stick, it’s just an RF to data convertor, the software does the all the work. I use CubicSDR here which does stereo but doesn’t decode RDS last I looked. I can see the RDS subcarrier on the screen though. RDS decode would be nice though since I have one site that does have RDS turned on and the rest might in the future. The thing is quite sensitive though, I’m using my RTL-SDR v3 (in the grey metal box) with a 2m/70cm dual band handitalkie antenna to listen to 50kW 90.7 about 20mi from me clearly.

So which one(s) does RDS ?
I did a quick look and could not confirm RDS
Some are amazingly cheap
Not sure my 175$ RDS Play does RDS

I use one for a quick and dirty test tool. I wouldnt count on it for accuracy though.

Works well enough to see some spectrum, check rds, check out the band, etc....

Anyone using one of those SDR USB dongle receivers either as a modulation monitor, or any other application in a broadcast environment?
