The ghpsdr3-alex Project

This is a modification of the excellent Software Defined Radio (SDR) software by John Melton ([G0ORX/N6LYT][1]

The original software by John is called ghpsdr3. We are working towards merging the two projects (ghpsdr3 and ghpsdr3-alex) source trees to a single source. However BEFORE that happens, you CANNOT mix and match programs from the two projects. See note for HPSDR hardware users below.

Project README https://github.com/alexlee188/ghpsdr3-alex/blob/master/README [2]

Source Code is via git at https://github.com/alexlee188/ghpsdr3-alex [3]

Project Goals

1. Open source (GPL) SDR software

2. Client-server network-enabled by design from the ground up

3. Customized server for each SDR hardware type. Currently supporting HPSDR, Softrock, Microtelecom Perseus, and Ettus Research USRP.

4. Single dspserver that connects to single server. However, each server can have multiple Rx and Tx channels.

5. Multiple clients, such as QtRadio, that can concurrently connect to a single dspserver.

6. Full Rx and Tx capability for hardware capable of Tx

• Screenshots and Recordings
• QtRadio on Windows
• QtRadio - Operation
• QtRadio Installation
• aHPSDR Android Client
• Pulseaudio Setup
• Developers Documentation
• ToDo/- Wishlist

Note for HPSDR and ghpsdr3 (original) users: In general, you cannot mix and match software from the two projects, ghpsdr3 and ghpsdr3-alex. However, John has updated the programs in the ghpsdr3-alex repository, and the "server" program works for HPSDR hardware (for Rx only currently, Tx coming shortly). We are using John's new binary header format so the dspserver is NOT compatible with "old" software from ghpsdr3. Use the "new" header format software from the ghpsdr3-alex repository. We also have a ppa for Linux and Windows versions of QtRadio. The "new" Android client and Java client from John will also work with the gphsdr3-alex dspserver.
