You need to install SDR# and the Zadig driver to use Raydel's app. A Quick Start Guide is available here. Also of course you need RSS which can be downloaded here: http://radiosky.com/spec/Spectrograph.exe
After installing RSS, you can download and run RTLW. I have placed a copy on my website. Raydel may wish to put future versions somewhere else. Download and unzip the folder to someplace you can find it. There is no install procedure. You might want to create a shortcut to the exe file.
Plug in your dongle and try it out with SDR# first using SDR#'s own drivers. Once you are satisfied that it is working, run RTL-WideSpectrum.exe from wherever you installed it.,
At first you need to select a gain and then a frequency correction. Finally you must select a total spectral width (5,10,or 20 MHz), and a center frequency for the lowest frequency spectrum.
Run RSS in stand alone mode and select Options /Radio /RTL dongle receiver. Then press the Start button in RSS The charts should start scrolling. If the signal looks too hot, stop the chart and restart RTLW with less gain. I am using 28 for the gain.
Raydel says that there may be some updates coming and he is aware that there are some things that could be done to make the program easier to use but what he has provided is very workable and probably as effective as you will get using this method to increase the bandwidth of the RTL generated spectra. Obviously, I would love to make RTL Bridge a better performer by using some of Raydel's methods, but I am currently just too busy to work on that project and hope you will enjoy CM2ESP's innovative work.
