For V4 users, download the latest RTL-SDR Blog drivers from the GitHub releases page and copy the rtlsdr.dll file into the Program Files\CubicSDR folder.

Here are the basic steps for setting up HDSDR and CubicSDR:

HdSDR Setup (Win XP+) is a straightforward process. You can download the software from http://hdsdr.de/, using the download button at the bottom of the page.

The first step is to install the RTL-SDR drivers via Zadig. You'll need to follow the Zadig guide to install the drivers.

Once the drivers are installed, you can proceed with the HDSDR installation by running the installer you just downloaded.

To set up the RTL-SDR, you'll need to copy the ExtIO_RTL.dll file into the HDSDR install folder, which is by default set to C:\Program Files (x86)\HDSDR.

When you open HDSDR, you might be asked to select a .dll file. Choose the ExtIO_RTLU.dll file you just copied over and then click Open.

To start the SDR, click on the Bandwidth button or press F6, and choose an output Sampling Rate of 48000 Hz for general NFM signals, or choose 192000 for wideband FM signals, like broadcast FM.

Press Start or press F2 to start the SDR. You can then set the RTL-SDR sample rate, gain, and frequency correction by clicking on the green "SDR-Device" button.

For the V4, make sure that "IF AGC" is NOT selected otherwise you may experience problems.

The FFT Display Panel in your SDR setup is where the magic happens! You can select either the FFT display, Waterfall, or both to view your signals.

The Window option allows you to choose from various FFT processing types, including None, Hamming, Blackman, Blackman-Harris, Hamm-Poisson, and Youssef. Each filter has its own response curves and envelopes.

Resolution is also crucial, and you can adjust it from 512 to 4194304 by powers of 2. 4096 is the default selection, but I've found that 16384 is a good compromise between display quality and performance.

You can also use Time Markers to display Date and Time markers on the left side of the Waterfall display every 10 seconds with default settings in the SDR# config.

The S-Attack, S-Decay, W-Attack, and W-Decay options all affect the response and appearance of the FFT and Waterfall displays, so feel free to experiment and find the settings that work best for you!

First, if you already have some other drivers installed, please purge them from your system using the following commands. This will ensure a clean slate for your RTL-SDR setup.

To purge existing drivers, you can use the commands provided in the instructions. I've found that this step is crucial in preventing conflicts with the RTL-SDR drivers.

Next, you can install the RTL-SDR Blog drivers using the following commands. This will get your RTL-SDR up and running.

After installing the libraries, you'll likely need to unload the DVB-T drivers, which Linux uses by default. To do this, type "sudo rmmod dvb_usb_rtl28xxu" into terminal.

For a permanent solution, create a text file "rtlsdr.conf" in /etc/modprobe.d and add the line "blacklist dvb_usb_rtl28xxu". You can use the one line command shown below to automatically write and create this file.

Some devices, like the Orange Pi zero, have a bug in their current mainline OSes, so you may need to blacklist "dvb_usb_rtl2832u" instead. Just update the black list file at /etc/modprobe.d/rtl-sdr-blacklist.conf manually too.

Now you can restart your device. After it boots up again, run "rtl_test" at the terminal with the RTL-SDR plugged in. It should start running.

Then, click on the Bandwidth button or press F6 and choose an output Sampling Rate of 48000 Hz for general NFM signals, or choose 192000 for wideband FM signals.

Here's a quick rundown of the steps to get you started:

For the RTL-SDR V4, make sure that "IF AGC" is NOT selected, as this may cause problems. To tune to a station, change the Local Oscillator frequency to a frequency near the station's frequency, then tune to the desired frequency either by clicking in the RF spectrum or using the Tune numbers.

The Radio Panel is where you'll spend most of your time when using HDSDR. It's a comprehensive section that lets you tune in to your desired frequency with precision.

To start, you can choose from various modulation modes, including Narrow FM, Amplitude Modulation, Lower Side Band, Upper Side Band, Wide FM, Double Side Band, Continuous Wave Lower, and Continuous Wave Upper.

The Frequency field is where you enter the current tuned frequency. Keep in mind that if you enter a frequency outside the current display range, the frequency won't change, so make sure to select a new Center frequency that's the same or near the desired new frequency.

You can also input an offset if you're using an upconverter or downconverter by checking the Shift box and entering your offset.

The Front End / Input Select field allows you to choose your desired input device, which could be RTL-SDR via TCP connection, RTL-SDR via USB connection, FUNcube Dongle, SoftRock / SiS570, or Other.

The Filter Type field lets you select the desired filtering type, which affects the demodulated signal audio response curve due to differing envelopes and filtering profiles.

You can also adjust the Filter Bandwidth to change the effective width of the signal being processed for the mode selected.

To reduce noise, you can turn on Squelch and select the level with the box below it. Squelch levels may change depending on filtering type and mode selected.

CW Shift allows you to change the frequency shift in either CW mode, similar to changing a BFO (Beat Frequency oscillator).

Snap To Grid forces frequency to snap to frequency steps selected when drag tuning.

Correct IQ enables SDR#'s exclusive Automatic IQ Correction, which is useful for improving signal quality.

Swap I & Q swaps I & Q inputs, which is useful when using sound card input devices and swaps L/R inputs to I/Q.

Mark Peaks displays a marker on detected peaks above the noise floor, which can be helpful for identifying signals.

The Frequency Manager Panel in HDSDR is a powerful tool that allows you to manage your frequencies with ease. The panel is located in the SDR# folder and has two main functions: adding and deleting frequencies.

To add a frequency, click on the "New" button, which will add the current frequency, mode, and center to the frequency.xml file. This file is used to store your frequency settings.

You can delete a frequency by clicking on the "Delete" button, which will remove the selected frequency from the visible list. The list can be sorted by name or frequency in either direction by clicking on the title bar.

The Frequency Manager Panel also allows you to customize your frequency settings, making it easy to organize and manage your frequencies. By using this panel, you can streamline your workflow and focus on what matters most - tuning in to your favorite stations.
