Why didn't my product come with a disc with the required software?
We no longer ship discs with most of our products. All of the required drivers are available in our Installation Guide, as well as some recommended software.
Why isn't Cubic SDR working on my PC?
You may have installed the wrong version. There are two versions of Cubic SDR, one is 32-bit, the other is 64-bit. Depending on your computer system, you need either one or the other. If you’ve installed the 32-bit, uninstall this and install the 64-bit instead, or vice versa.
I can't get HDSDR to work on my PC.
For this program, you need to be sure to download the zip file found in our Installation Guide. The zip file contains installation instructions, along with a library file and program file. When installing HDSDR, you need to note the location of the Installation Directory (program file) and move the library file (.dll) to this location, as per the installation instructions. Without completing this step, HDSDR will not be able to recognize your device.
I am using HDSDR and I can't seem to pick up any signals. What can I do differently?
When using HDSDR, there are a number of software settings that can be adjusted to improve the performance of your SDR. Please note that these settings are generally recommended, but will need to be adjusted depending on your signal of interest and operating environment. As with learning any new software program, some trial and error will be needed to find the settings optimal for your application. With that said, these are our recommendations when working with HDSDR:
- Disable AGCs (automatic gain controls) and adjust the gain manually.
- Ensure that you have selected the correct demodulation type for your signal of interest (for example, the setting for FM radio is FM).
- Set the sampling rate (bandwidth) appropriately for your frequency. For FM radio, the bandwidth settings should be 96,000 (input) and 192,000 (output).
- Set the LO frequency and the tune frequency slightly apart (start at about 10 kHz or so and increase depending on the bandwidth of your signal of interest).
Can I use your product with GNU Radio?
Yes, our NESDR series is fully compatible with GNU Radio. However, Nooelec does not provide technical support for this software.
I want to use my device for both SDR and DVB-T, how does this work?
The drivers for SDR and DVB-T are not compatible with one another and would have to be switched when using a different function. You would need to uninstall one when using the other and vice versa. A simpler method would be to use separate USB ports for each function, as Windows keeps drivers for USB devices on a per-port basis.
I have just downloaded the NESDR Driver Installer, but my antivirus software is identifying the file as corrupt and removes it. Is there an issue with the file? How can I fix the problem?
This is a common problem associated with some antivirus software. The file is an un-archived, executable file, which is capable of installing core files. This is both what it is designed to do, and also why the antivirus software is preventing you from opening it. You should disable your antivirus software temporarily to install the driver, and then re-enable it.
Can you help me to tune into a specific station or frequency in my area?
It is very difficult to assist a remote customer in tuning to a specific station in their area, as the settings within the software will vary depending on a large number of environmental factors that are unique to each individual set-up. However, here are a few things to look for to get you started:
- Select the correct demodulation type for your frequency of interest (for broadcast FM radio, it would be WFM);
- Tune the software to the correct frequency;
- Use the appropriate antenna for the frequency;
- Set the bandwidth to the correct value, depending on your signal;
- Set the gain appropriately (we recommend disabling AGCs for most purposes).
I'm using SDR# with my SMArt XTR dongle, and the performance is quite poor!
While SDR# is a popular software, please note that Nooelec is unable to offer technical support for this particular program. That being said, we do have some recommendations for resolving this problem.
The first thing to know is that SDR# doesn't play very nice with E4000 SDRs compared to some alternate software, especially if using the default RTL library and not one more suitable for E4000.
If you want to make SDR# work with your XTR dongle, we recommend not bothering with the AGCs. You are better off in most cases with the gain sliders. As for the static, make sure you have enabled offset tuning, and I/Q correction. This is very important for E4000 based SDRs.
Hopefully these tips will improve your initial impression of the SDR!
Where can I find the software for DVB-TV?
We are happy to provide HDTV software free of charge. Download it here.
