Getting Started with RTL-SDR V4 in Airspy SDR Sharp (SDR#)

hello and welcome back to my channel this is V3 z a Sur here today we'll be discussing about arsd V4 dongle and how to make it work on SDR sharp application for Windows let's talk little bit about V4 version as for the physical appearance it is pretty much similar to that of V3 version the V4 version is basically based on the r828 D tuner and uh there are a lot of features as compared to the V3 version the most interesting part is improved HF reception and uh this uh particular dongle uses built-in up converter instead of a direct sampling and other features are like improved filtering and improved power supply design here is my setup arsd is connected to a laptop using uh USB port the SMA connector is connected to an external efsw antenna through this coax cable now let's start the configuration part open your PC browser and uh go to RTL SDR uh blog SL V4 uh there you can find a well documented user guide related to uh tsdr d uh V4 so as you can see uh there are some circuitry changes been made in the new design and uh for that reasons uh new driver need to be installed and uh also so the interesting part is that this new driver is Backward Compatible with the older versions of the RL SDR so uh first of all we need to replace the existing drivers with the new driver and uh as for the description it is an easy task so we'll be focusing uh uh more about uh SDR Shar software uh that uh I found uh very useful uh while uh working on this RTL dong all you need to do is go to the rout directory of SDR shop and uh you have to rerun the install rtlsdr dobat F again and uh make sure that uh your internet connectivity is on so that it will automatically download the packages and uh replace the existing drivers now let us connect the rtlsdr to the PC and let's check the device maintenance so as for the device maintenance I can see a new device has been detected now let us browse to the root directory of s strr sharp application here you have to find the file named install hyphen RL SDR dobat now you have to execute it make sure that you are connected to internet the batch file will automatically download the required drivers and replace the existing drivers once it is completed exit the window now let us open SDR sharp application as you can see the device detected in the device manager is still showing the same icon this is just an observation I'm sh ing as we already know that uh V4 dongle have inbuilt up converter so we can uh change the sampling mode uh to quadrature sampling and uh let us first explore uh the VHF frequencies so the simple and easiest uh way I uh think is we can tune to a broadcast uh station on VHF range so I'm getting few stations here uh around this frequency let's try to tune it okay uh so okay here we go uh let's increase the RF game of the tuner okay so excellently we are able to receive the broadcast FM [Music] signal so there are other stations also at around 98 MHz frequency excellent cop now next part is uh let's explore the HF part so as we already know there is an inbuilt up converter still uh let us explore the user manual and the manual says uh we don't need to modify the sampling mode uh to direct sampling as we uh used to do for the older version here we can use the same settings of quadrature sampling mode and uh we can straight away go to the lower frequencies of HF So currently I'm uh uh trying to monitor the HF frequencies and uh it's uh daytime here uh so let's uh check the upper brand like uh 21 MHz and I will try to monitor the digital frequencies of uh like ft8 uh frequency uh to check whether I'm able to copy the ft8 signals [Music] so here we go I am able to excellently copy this uh uh ft8 digital mode signals and uh I can straight away modify the RF gain of this particular tuner uh with the settings over here so it is very interesting and uh a very good uh feature addition uh as we all know that uh this V4 is a limited edition so uh uh you can uh grab one uh as earlier as possible if you wish to have one in your collection so hope you guys enjoyed this video and uh uh there are lot of things that we can explore using this new version if you enjoy the video click the like button and do share thanks for watching 73
