Welcome to the website for Zefie's HackRF Plugins

What are they?

Zefie's HackRF Plugins are a set of plugins for SDRSharp that enables gain, intermediate frequency, and amp control,
via either USB or Ethernet (via hackrf_tcp).

Extras (Updated 2014-01-08 [feat. hackrf_tcp beta])

You can download my pre-compiled hackrf-tools (includes 32-bit and 64-bit) for Windows here:

Current Version

The current version is currently v1.7.


Aside from this site, you can also find the plugin binary and source on my GitHub:


  • Source code is included, no change in license.
  • Allows enabling (Default) and disabling the HackRF internal AMP
  • Allows gain adjustment
  • Allows intermediate frequency adjustment
  • HRFTCP allows accessing your HackRF over a network, like with rtl_tcp

Known Issues

  • The plugin is still in alpha/beta state and may not operate as desired.
  • Updating to v1.4 from an older version will reset your stored LNA and VGA gain values.
  • If you receive an error from SDRSharp, you may need the Microsoft Visual C++ 2012 Redist

Pending Feature Requests

  • Enable TX mode via hackrf_tcp / By zefie
