Previews

Congratulations, you've found the preview page. Bookmark this page and visit it regularly, otherwise you may miss out on exciting new SDR software.

Please remember:

  • This is a Preview, it gives you an idea of the future direction my code is taking.
  • It is not a beta.
  • It is not a release.
  • It is not finished.

Support

Direct support from developers for version 3 is only available for commercial customers. Please do not send direct e-mail asking for support; sufficient resources are not currently available, instead you will be redirected to this page. Answering questions on a one-to-one basis is very inefficient.

  • The user group is hosted by Groups.io! at https://groups.io/g/SDR-Radio.
  • Help is available on-line only, to access help select Support from the Help pane in the program's ribbon bar.

New Features

Please do not ask for extra features or a road map. This is a preview, that's all. A road map will be created by the end of 2017.

... even if there was never another change made to this "Preview", it would still be the best SDR software I have ever encountered - and not by a small margin.

I had the idea with V2 that the user can get everything they want with enough fiddling, everything is included, but V3 makes it sooo fast and easy - intuitive. The program is faster and more fluid.

Amazing...


 

Computer Requirement

A third-generation i5 with HD graphics or a dedicated graphics card running Windows 10 is recommended:

  • CPU: The i5 has more than enough performance for the present demands of this software and should be powerful enough for any new features which will be developed during 2017 and 2018.
  • GPU: The HD graphics or even better a dedicated graphics card ensures a good, 'fluid' experience. The software uses DirectX which makes full use of any graphics processing on your computer. If you are considering a graphics card NVIDIA is recommended as this card can be optionally be used for DSP processing.
  • Monitor: Use a HD monitor (1920 x 1080) or if finances allow a 4k monitor - if you buy a 4k make sure your graphics card will run a 4k monitor at a 60Hz refersh rate.
  • Windows: You must use Windows 7 or newer; Windows 10 is excellent - despite some initial roll-out issues it is a tour de force and is the recommended operating system.

Introduction

Congratulations, you've found the preview page. Bookmark this page and visit it regularly, otherwise you may miss out on exciting new SDR software.

Please remember:

  • This is a Preview, it gives you an idea of the future direction my code is taking.
  • It is not a beta.
  • It is not a release.
  • It is not finished.

Support

Direct support from developers for version 3 is only available for commercial customers. Please do not send direct e-mail asking for support; sufficient resources are not currently available, instead you will be redirected to this page. Answering questions on a one-to-one basis is very inefficient.

  • The user group is hosted by Groups.io at https://groups.io/g/SDR-Radio.
  • Help is available on-line only, to access help select Support from the Help pane in the program's ribbon bar.

Getting Started

First you must:

  1. download, then
  2. install the software.

This is documented in full detail on the getting started page [link].

Version 3

  • Requires at least Windows 7,
  • Uses Direct2D (DirectX)for graphics,
  • Uses WASAPI for audio,
  • If a NVIDIA card is installed then it is used for DSP processing , if not installed the CPU is used,
  • Transmit support for ANAN transceivers and other hardware which supports the new firmware from Phil Harman VK6PH (Q2, 2016),
  • Favourites (similar to web browsers),
  • Unlimited receivers (VFOs),
  • Integrated digital mode support which can run as a top-level program on a second monitor,
  • Satellite tracking with full Doppler correction (TBA),
  • External radio support (TBA).

From MSDN: Direct2D is a hardware-accelerated, immediate-mode 2-D graphics API that provides high performance and high-quality rendering for 2-D geometry, bitmaps, and text. The Direct2D API is designed to interoperate with existing code that uses GDI, GDI+, or Direct3D. Put another way - it's much faster than the GDI/GDI+ graphics used in versions 1 and 2, will work with multiple 4k monitors without using all system resources, has a nice fluid display.

Receive

The internal design changes in V3 results in an unlimited number of simultaneous receivers (VFOs). In a future release it will be possible to display the receivers in a matrix display.

For more receiver information click here.

Transmit

This is the first time software from SDR-Radio.com has supported transmitting.

For more transmitter information click here.

Hardware

The software will run on a small Z3735F ATOM system such as the Quantum Byte Fanless Windows® Mini Desktop PC but only at low bandwidths (typically less than 1 MHz), anything higher can lock up the software. If you want a nice and nippy PC then the suggested minimum configuration is:

  • 64-bit Windows 7, 8, 10 (10 is recommended)
  • 4GB RAM (8GB is better)
  • 128GB SSD Disk for Windows
  • i5 4th generation or better, any CPU frequency (i3 if on a tight budget)
  • Intel HD graphics or AMD equivalent
  • If you are buying a graphics card then NVIDIA is recommended (more information below), if your CPU chip does not have built-in graphics (example: i7-980X) then a graphics card will improve the overall SDR 'user experience'. Even if your CPU has built-in graphics a graphics card enhances the graphics quality.

V2.x and V3

Version 2,x and 3 use separate file system and registry folders, they can both be installed at the same time without problem.

CPU Load

An important feature is the low CPU requirement, achieved by:

  • Using the Intel IPP library,
  • Using hardware accelerated graphics (in this case DirectX) rather than the traditional GDI/ GDI+,
  • Minimise memory allocation, recycle rather than free,
  • Attention to the code - every cycle counts.

The result of saving cycles during the processing is that it's possible to implement a more fluid and mature user interface, especially the spectrum and waterfall with opaque overlays.

NVIDIA CUDA

If you have a NVIDIA graphics card then this software will use the graphics card's processor for the CPU-intensive FFT processing (convert the SDR radio data to the waterfall and spectrum display). This

  1. offloads the processing from your CPU (Intel or AMD), and
  2. is advantageous when running radios with a bandwidth of ~ 2 MHz or higher together with enhanced resolution. Radios with higher bandwidths are Airspy, SDRplay, Ettus B200, LimeSDR etc.

It is not essential that you have a NVIDIA graphics card, but if you are going to buy a graphics card then buy NVIDIA with compute capability 3.0 or higher, for a list of NVIDIA GPUs:https://developer.nvidia.com/cuda-gpus . A good value for money card is the GTX 950, if you want a good budget card then look at the GT 730.

Note:

  1. CUDA is enabled in the NVIDIA graphics card, there's nothing for you to configure,
  2. The FFT processing uses the CUDA cores by default - if the graphics card has any that is!

 

Known Bugs

Before reporting errors please look at the Known Bugs page. This lists the major problems with the currently available kits.

 

Error Reports

If you see a small 'Please Wait' window followed by a BugTrap error report please upload the contents of the error report to the cloud, for example with one of these free providers:

Then send an e-mail to simon@sdr-radio.com with the link to the uploaded files. All object and symbol files used by preview kits are stored so that the crash dumps can be successfully analysed.

Thank-you!
