Introduction

The SDR Server supports one or more SDR radios located at a remote location, the internet is used to connect the SDR Console to the server. Use the Server Manager (below) to configure and start the server (runs as a Windows service). The server also supports up to ten simulateneous connections (one radio per user), so the practical limit is your internet upload bandwidth.

To determine your upload bandwidth use one of the many websites such as http://www.speedtest.net which will gives results such as shown below.

The recommended minimum bandwidth is 2 MBps (two megabits), more is better as it allows a higher sample rate between the server and the console.

The server does not require a high-end computer - tests have successfuly concluded on a 32-bit Windows 7 laptop with a 2GHz Core2Duo processor, the CPU load typically less than 2%.

The server sends IQ data (In-phase and Quadrature), this is the same data your SDR radio creates so you are effectively running a SDR radio with the internet between. By sending over IQ data you lose none of the features available when the radio is connected to your local computer.

Note: Transmit support using the V3 server is not currently planned.

 

Connecting

Note: The connection logic changed with 3.0.11 to simplify the process. With 3.0.11 when you connect to a server a list of available radios is displayed, so if the server owners adds or removes radios what you see is the current status. Also, there's only one entry in the Radio Definitions window for each server rather than one entry for each radio on a server.
  

Add Definition

To connect to a server you must first add a server definition:

  1. From the ribbon bar select Home, Radio, Select Radio.
  2. In the Select Radio window click Definitions...
  3. In the Radio Definitions window select V3 Server at the bottom of the Search list.
  4. The Autodetect window is displayed.
  5. Enter the Address, Username and Password, then press Select. You can also select a worldwide server from the SDRSpace.com list.
  6. If the server can be contacted a list of radios is displayed.
  7. Now press OK.
  8. A new entry is added to the Radio Definitions window.

 

Starting

To connect to a radio simply select the entry in the Radio Definitions windows and press Start.

A new window is displayed with a list of the radios on the server and the current status. Select an available radio, the bandwidth and press Start.

That's it!

 

All receivers have a Signal Meter (S Meter). SDR Console offers a digital bar and a psudo analog meter.
