How to receive
Appearance
It is very to receive your and other people signal with RTL-TCP.
Most of SDR applications support RTL-TCP, Took SDR++ as example:

Q&A
Q: What sample rate should I use?
- 250KHz (0.25MSPS) for receiving Shortwave and lower band
- 1.024MSPS (or higher) for receiving FM, wide signal
Q: I don't see anything?
- Make sure you type in the right information
- Make sure you are tuned in the right frequency
- Try using manual gain or RTL-TCP if you are on higher band
Q: What band should I receive?
- Try 60m SW band (4700 - 5100KHz)
- or FM band (87.5 - 108MHz and recommend using RTL-AGC / Manual gain)
Q: I don't see the port box.
