New Computer Line-up announced

SDR users now have four computers specifically designed and tested, component by component, for optimum performance.

A new computer designed for small operating spaces, RVs, dxpeditions, etc., is available. The Incredible Small-Form-Factor Computer has the power to run Flex-3000s and 1500s with a low power-consumption footprint.

The new "King of the Hill" is The Ultimate Op Computer. This is a crazy-powerful machine, powered by Intel's i7-3930 6-core, 12-hyperthread CPU which blows the lid off of benchmarks. Connect up to 6 monitors and know you have a machine that your son/grandson will tell his friends about!

The premium The Dx'ers Dream Computer is using the Intel i7-2600 CPU, which is the most performant versus cost processor Intel has ever produced. This dream machine will meet all of your needs for many years in the future.

A new Entry Level Computer rounds out the new line-up of SDR computers. Sporting the powerful AMD Phenom II X6 965 4-core CPU, you will comfortably drive all Flex radios at an incredible price.

All systems now use Windows 7 64 bit operating systems.

Spot 1.9.12 enters beta test

Spot version 1.9.12 is available for beta testing. This version fixes the incorrect headings and some small bugs. The main bug remaining is with alarm notifications.

Send email to K3NC if you would like to test!

Computer Systems fine-tuned for SDR activities

One of the critical success factors in using modern software-defined radios (SDRs) is often overlooked during the decision process of buying a new radio: your computer. In the early days of experimentation with SDRs, we thought that processor speed and overall computer utilization was the critical success factor. A holdover of this school of thought is that many SDR consoles show the system utilization on the main panel.

It was a bit of a shock, however, when new SDR owners, who do not spend days tuning their systems, started running into troubles. They would buy the latest desktop computer from the local big-box store, plug in the radio and start seeing problems. These problems are evident by the console freezing up or losing communications with the radio (which is just on the other end of the FireWire cable!) These computers normally had the latest in CPU technology and their computer system had every bell and whistle ever imagined, yet it couldn't run a program that a small system such as an Intel Atom 330 could run with no problems (if set up correctly).

The four critical success factors for a SDR computer are:

1. Properly selected computer components that provide adequate power and overhead when needed,
2. very low latency at the driver layer of Windows (properly written drivers),
3. congestion on the IRQ that the FireWire or USB cards are using, and
4. and tuning Windows so it doesn't interrupt audio processing.

Each year we test many new components, solely with the goal of identifying the best components to use in each of our computer systems. Some end up in surplus computer systems that we sell merely to recover our costs (if you are looking for a good system not related to Software Definied Radios, please drop us a line!) As opposed to other dealers, we select each part (even non-sexy ones of things like power supplies) for the quietest, lowest maintenance usage in the shack.

Some components, using well-known chipsets, still can be problematic due to poorly-written drivers. These drivers result in to a very high rate of Deferred Process Calls (DPCs) which will block the data path through the I/O subsystem of a PC.

Unfortunately, many motherboards also engineer the peripherals (whether the built-in type or ones you plug into a PCI/PCIe slot) only on a few (often just 2) IRQs. A recent Dell computer in my shop had all peripherals assigned mainly to IRQ 16 and 17. There was no way this system would run well as a SDR computer without turning off some of the system devices. Long gone are the days where users could assign the IRQ used by a device!

The Windows operating system itself can be a cause of problems. For instance, Windows will try to provide lghtning-quick search by continually reading any file that has been updated and building indices of file names, words contained within the documents etc. This type of search and analyize function can fire ever minute

Why should I buy a computer from you instead of the ones I see at Walmart/Costco/etc.?

If your biggest priority is to get the absolute cheapest computer for your new SDR, look for a good AMD-based computer at your local store of preference. You want to look for a multi-core processor AMD processor, 3.0GHz or fasfer running Windows 7 with at least 4GB of memory. You will want a processor type that has Phenom II, Athlon 2, FX or A Series. If possible, make sure it has an AMD controller (you will see specifications like 990. 880. 765,etc.)

We offer 4 computers specifically configured and tuned for use with your Software-Defined Radio:

  • The Entry Level Computer, which is a system for those just starting out with a Flex-3000 or 1500.
  • The DX'ers Dream Computer, a premium-level machine that will last many years in your shack,
  • The Incredible Small-Form-Factory Computer, designed for very small shacks or RVs.
