RTL-SDR Blog V4 R828D RTL2832U 1PPM TCXO SMA Software Defined Radio (Dongle Only)

I purchased the RTL-SDR V4 to upgrade from the V3 which I've had for over a year. I usually listen to the HF amateur bands and the V4 seems to be much better in this regard - less noise and interference and better sensitivity. I don't have a great setup - just a long-wire antenna about 13 meters long in the back garden but have heard contacts from all over the world. The unit does get very warm in use and, even though they say this is normal, so as not to shorten it's life I have attached an extra heatsink so that it now runs much cooler. I have tested it on the air bands, marine bands and commercial bands and all work just fine with clear reception. If you already have a V3 for listening to HF and are thinking of upgrading I'd suggest this is a good purchase especially for the price. There is less benefit to UHF, VHF etc so if this is your usual listening range the V3 is probably already more than adequate.

Nice I’ve got a few but this especially with dsdplus paid version works well but there more info on it look it up Outdoor antenna works well

Work very well for the price.

Works as expected and is identical to the ones I got from the official outlet on Aliexpress where they are £11 cheaper, requiring only patience for delivery. There are a few niggles with the design - The SMA connector is set back on the PCB a couple of mm which means if you tighten the SMA nut, you will be pulling on the solder joints. The extruded case has screw mouldings on all four corners but they chose to only put two screws in each endplate to save pennies and these are coarse self-tappers that shed particles of aluminium swarf every time you undo them and why they chose countersunk heads in a non-countersunk plate is a mystery. I wanted to panel mount a few of these dongles but the SMA is too short to be able to poke it through and add another nut for proper grounding, again it's that bizarre set-back on the PCB. It's pot luck whether you receive a dongle with the USB plug soldered on straight.

It's a brilliant device but it's only as good as the antenna you use with it.

This is a very affordable SDR. It isn’t exactly plug and play and took some googling to set up but I’m not an expert and for the price should expect to have to put in a bit of work to get it set up. So far I’m really happy with it and it can be used with a range of different sdr software

For a relativly small inexpensive item you can listen to transmissions around the world. Build quality is solid, it does get warm. The in built up-converter makes a real difference and really sets you up to explore this hobby. A better antenna is going to improve the signals but a long wire is a good starter. Endless fun for not much money.

Tried to get it to work on a Raspberry Pi 4. Two operating systems tested (using CubcSDR) - Trixie and Bookworm. Didn't work at all on Bookworm, and Trixie was unreliable. Nooelec alternative runs fine, same hardware and software, so I know this unit is faulty. Maybe just an unlucky unit?

安いSDRモジュールを試していましたが、Macだとノイズが乗ってしまいます。これに変えたところ、ノイズがなくなりました。Windowsでも問題ありません。

Ottima, sotto tanti punti di vista. Bisogna fare riferimento alla documentazione ufficiale riportata nel sito. Bisogno installare driver e librerie C++ per farla funzionare. Poi va utilizzato uno dei tanti software a disposizione. L`ho installata con successo su Win11, Kali e Mac. Per linux bisogna aggiornare il source packages, ma con un pò di pazienza funziona tutto. L`utilizzo dei software come ad esempio sdr++, può avvenire solo dopo aver configurato correttamente i drivers. Funziona, basta seguire le guide. Dotatevi di antenne adeguate.

Thank u for Seller services

This is the second dongle I bought, and it works PERFECTLY after I did the RTFM trick The first one I bought, I couldn't get to work, so I sent it back because it would not connect to my Ubuntu OS This one, I googled how to install it to a linux computer and also installed GQRX as my receiver to receive 10Ghz amateur radio with a BullsEye LNB at 618.368.100USB it also lets me receive the same stations on my Quansheng WT unit at 618.100mhz

Funciona muy bien aunque si es muy necesaria una buena antena al exterior,
