HPSDR (including Hermes Lite 2) device notes

Setup

Support for HPSDR receivers uses the HPSDR connector at https://github.com/jancona/hpsdrconnector

Building the connector

1. Download Go from https://golang.org/dl/
2. Install Go, following the instructions for your OS at https://golang.org/doc/install. Be sure to add the Go bin directory to your PATH if the installer hasn't done that for you.
3. Install Git using your OS's package manager, e.g. sudo apt-get install git.
4. Clone the hpsdrconnector repository: git clone https://github.com/jancona/hpsdrconnector.git
5. In the hpsdrconnector directory, run go install to build and install the connector.
6. Test your installation by running hpsdrconnector -h. You should see a usage message.

Usage

In order to use hpsdrconnector with OpenWebRX you will need a version of OpenWebRX that supports it. Until OpenWebRX 0.21.0 is released, you will need to follow the manual installation instructions. Once there is a new release, a normal installation will suffice.

You will also need to update config_webrx.py. Here is a sample SDR definition:

# Limitations
* Only the original HPSDR Protocol 1 is supported.
* So far, this has only been tested with the [Hermes-Lite 2](https://github.com/softerhardware/Hermes-Lite2/wiki). Feel free to create [issues](https://github.com/jancona/hpsdrconnector/issues) with reports of success or failure using other hardware.
