Yes, also with a lower sample rate (1024) the bandwith is too much....

Just to clarify, I use SDR Sharp (SDR#) on a Windows 7 PC (Client side) to connect on the RTL SDR on the Raspberry Pi (Server side).

If I use my LAN connection no problem at all, but the bandwith is too much for stream over my Internet Connection (1 Megabit/sec in upload).

Obviously I do not want to stream, for example, Wide FM Broadcasting over the Internet beacuse the audio bandwith is very high, but I would like to stream over the Internet the SSB mode (300 Hz to 3400 Hz) where the audio bandwidth is not so much.

So how Can I limit the maxium bandwith by using (Server side) the rtl_tcp command?

I'm pretty sure that with a bandwith of about 3 kHz and a sample rate of 1024 1 Megabit of Internet bandwith can be enought....

I use also the Perseus SDR receiver (by Microtelecom) with it's Server feature (stream over the Internet) and it works very well, my 1 Megabit of bandwith is enought.
