Step by step instructions on program baofeng mac 2 for police codes full#

The SPY Server comes with a standard configuration file that allows you using Airspy or RTL-SDR directly without an upconverter. The bandwidth savings allows usage over the Internet, but still requires high speed connection. If the network bandwidth is not sufficient to handle the traffic, uncheck the “Full IQ” option and the server will only stream the FFT display data and reduced IQ data that it necessary for decoding one VFO.

The “Full IQ” option allows streaming the entire spectrum from the device to the SDR client (SDR#). The default settings allow using the server in the LAN with optimal latency. When there are more than one client connected, the center frequency of the device and the RF gain are locked.

When only one client is connected, full control (center frequency, gain) is granted. The SPY Server allows you to connect many SDR# “clients” to the same Airspy or RTL-SDR device over the network. Since revision 1553, we offer a new utility for the Airspy series to convert a Raspberry Pi, an Odroid, or just your regular Windows or Linux PC into a fully featured SDR server. In any case, you should make sure the RF noise floor just overrides the quantization noise floor of the ADC, but no more.

Fine tune to maximize the SNR (the blue bar graph on the right).

If not, increase the gain by an extra notch.

Check that increasing the gain no longer increase SNR.

Increase the gain until the natural noise floor rises by about 5dB.

The following fine tuning procedure ensures you have the maximum SNR on the signal of interest while preserving the dynamic range: The “Linearity” mode is the one you want to start with: As depicted in this screen shot, there are many gain modes: Then next step is the gain configuration. Then run SDRSharp.exe and select the “AIRSPY” front-end: Airspy was designed by the same people who developed the SDR# software so it’s the obvious choice for running Airspy and leverage all its powerful features.įirst, go to the download page and get a copy.
