SDR RTL receiver apps

[mmediaman]

Hi,
Can anyone here help me understand why some apps appear to be inferior when receiving signals from SDR hardware?

If I connect my Nano3 to SDRTouch on my phone it barely (did I say barely?) gets the same signals CubicSDR on a laptop gets using the same hardware, w/same antenna.

Is it a processing power thing? I like to think my phone is as powerful as my laptop...

🙏

Strange. Maybe there is some noise induced on the connection between the phone and the CubicSDR causing you issues, noise that might not be present when you have the CubicSDR hooked to your PC.

Thanks for the reply.
I think maybe you misunderstood the question.

I'm saying; why with the same hardware, one app that's on a PC (CubicSDR), performs much better than another app (SDRTouch) on a modern phone?

And I gave a possible answer. Good luck.

Try putting your phone in airplane mode while you have an SDR attached to see if that makes a difference. If it doesn't, I don't know what else would work. There shouldn't be any major discrepancies between using an SDR on PC or phone.

Thanks for the replies.
I was able to get SDR++ working on all my devices.
My conclusion is that some apps are just better than others and in my experience, SDR++ is head and shoulders better than the SDRTouch app I was trying to use. Hate that I paid for SDRTouch when something much better is free.

Look into SDR++ Brown edition on PC. Not sure if it works on phones but it's a great version, with built in DSD for monitoring conventional digital signals. Also has some really good built-in noise reduction for sw/hf listening, FT8 decoding, among other things including the ability to listen to kiwi/webSDRs.

Ok, thank you!

As a general rule, the quality of received data is highly dependent on the signal processing algorithm employed by the application software. Some algs require more processing power and can pull things out of weaker signals, while others are less cpu intensive and only capture strong signals. As with everything to do with SDR, you have to experiment to find what works well for you and your location.

Right. I think I've discovered the same now. (SDR++ > SDRTouch) Thanks 😎🙏
