Hallo, I decided to buy a SDR device for VHF/UHF DMR signals reception only. But looking on the WEB I found different opinions about SDR Blog v.3 and v4. I do not think that D828D chip is the best choice for VHF/UHF, but for HF band. I shall appreciate the best sensitivity. What is your advice ? ---

Finally I bought a RTL SDR Blog v.4. I think that the driver is the same of the NOOELEC SMart V.5. So, using SDR## application, it should be like a “Plug&Play” operation. ---

You can see the measured sensitivity graphs at [RTL-SDR Blog V4 Dongle Initial Release!](https://www.rtl-sdr.com/rtl-sdr-blog-v4-dongle-initial-release/) Basically the V3 has better sensitivity at VHF/UIHF, but the V4 will have better selectivity due to the filtering. As long as you’re using the latest version of SDR#, it will download the latest drivers that are compatible with the V4 when you go through the quickstart guide procedure. ---

Hallo Carl, thank you for your answer. Currently I’m using a NOOELEC Smart V5 (driver downloaded using ZADIG) device. The software on the PC (Windows 11) is the latest version of SDRSharp. I bought a few days ago a RTL-SDR Blogv4 from Aliexpress. It will be delivered next week. My question is if I should forced to follow the quickstart guide procedure for the new RTL-SDR, or simply I could exchange the devices on the USB port of the same PC. My final purpose is to check either the devices (alternately) using the same PC, and the same antenna. ---

It depends on how recently you did the installation for programs like SDR#. If you installed recently you would have the most up to date drivers already. If not, then you’d want to do the QSG from te beginning.
