Welcome to the website for Zefie's RTLTCP Plugin Mod

What is it?

Zefie's RTLTCP Plugin Mod is a plugin for SDRSharp that enables a Direct Sampling via RTLTCP (which is built into the latest rtl_tcp), as well as enables support for the modified Linrad Gain modes for the E4000 chip.

Why a "Mod"?

Direct Sampling support was missing from RTLTCP at the time of the mod, and Linrad E4K modes are not officially supported by OsmoSDR (creators of RTL-SDR)

See also: rtlsdr patches, and zefie's patched rtlsdr for windows (featuring previously linked patches (including Linrad E4000 Gain Mod)) (v2, built against libusbx)

Features

• Source code is included, no change in license.
• Allows enabling and disabling Direct Sampling mode from SDRSharp
• Supports Linrad E4000 Gain Modifications (don't use this if you are not running a modified rtlsdr source)

Known Issues

• The plugin does not check to see if the Linrad E4000 Gain Modifications are supported by the current rtl_tcp server.

Pending Feature Requests

• None.

Special Thanks

• prog (aka Youssef), for creating SDRSharp
