RTL-SDR No reception

#1

Unread post by G4GUJ »

Can anyone help me please?
I have a nooelec NESDR Mini2+ R820T2 & DVB-T USB RTL-SDR which my PC recognises as a HID Infrared Receiver (?) that I am trying to use as the front end receiver for SDRplay.
The software sees the device and appears to connect to it but I cannot get any reception - even when I try to tune to a known strong local VHF FM transmission.
Yes I have connected an aerial to it!
Does anyone have any checks that I can do before I send the USB dongle back to its maker??
Richard.

Not sure what a front end RXR is for an SDRPlay or why it’s required, since the SDRPlay is a DC to daylight RXR as it is.
RTL dongles all have to have the proper drivers installed, an executable called Zadig is what is used. Since the computer thinks it’s an Infared RXR, that might be the problem.

Directions for using the dongles is here, including driver installation:

a printscreen (with the device connected) would help Richard.

He needs to play with Zadig to replace the drivers Windows 10 found with winusb.sys. I believe there is a description of this on sdr-radio.com where you got SDR Console.

Many, Many thanks.
I ran Zadiq and replaced the driver now I have reception (of sorts)
For broadcast FM stations I cannot get the filter bandwidth wide enough but at least I now know the device is working and can now start experimenting.

Thanks again

Richard,
For FM Broadcast, you need to operate the mode in BFM (Broadcast FM). The button will be renamed BC-FM in v3.0.27 for clarity. If you don't have a BFM or BC-FM button in your Mode window of your DSP panel, you can add one via the three dots in the Mode window.

It doesn't take long to 'get the hang of it' using Simon's creation, SDRC. Like Amateur Radio, there are lot's of facets on how users utilize this powerful software as the posts on this website prove. More features and improvements are added with every update, either by Simon's own creative thinking or users posting suggestions here on the "Requests" area of this site.
