Hi Tony,

Sorry for the late reply. I don’t recommend trying to use a Pi-1 for RTL-SDR over WiFi. It’s unlikely to work well as it’s asking too much of the very low power processor in the original Pi.

Regards,

Mike

I have an old Pi1 mod.B rev.2 and I installed rtl_tcp, as Spy Server would overload it.

It has a Wifi dongle and I added the scritpt described in “Auto-Start rtl-sdr Server”. I plan to connect the Pi to the open Wifi of the entreprise network. Shall I add also the wpa-supplicant or would the Auto-Start rtl_sdr Server automatically connect to the only AP which has no password to enter ?

When I look at the local IP, it gives (partly, there are UDP ports not printed) the following (I don’t see anywhere any 1234 port) :

10.29.128.180:44376

tcp 0 0 10.29.128.180:36939

tcp 0 0 10.29.128.180:48170

tcp 0 0 10.29.128.180:60194

tcp 0 0 10.29.128.180:34979

There is a common public IP address, wherever I connect on the various AP in the premises. Do you think the Pi would be accessible from outside?

Shall I change the listening ports of both SDR# and Pi conf?

I hope I am not bothering you.

Thank you and best regards.

Tony

In reply to Shelaigh. Hi Shelaigh - I haven't seen anything for that using a Pi. In the existing server setup, the Dongle outputs its IQ data to the Pi using the USB port and the Pi then forwards the data to the host PC over the local network. The host PC needs to run SDR receiver software such as SDRSharp or SDR-Console to control the dongle and demodulate the signal using the IQ data. However, you could remote access your host PC using TeamViewer or other remote access software. That would allow you to operate your PC remotely. Mike

This was so helpful! Thank you for the info, I have been looking for a way to do this.
Is there a way to get only the audio from the tuner over TCP? I want to tune in a station remotely over the web, while recording the audio both locally into a file on the Pi and remotely in a 24 hour loop. My shed has been getting vandalized and I think this will help, Thanks in advance,
