以前に使用していた、SDRドングルより、安定した、受信が出来ています。 特に、耳で聞き取れない微弱な、信号でも、FT-8が受信出来るのが、素晴らしいです。 評判通りの商品で、満足しています。

価格の割に高性能です。v3より感度が良いと感じます。PCで動作に問題があった時は、給電も疑ってみて下さい。USBハブ等は通さずにPCと直接接続して下さい。

Great SDR, works well in many applications.
Been great using this to listen on the HF bands using SDR Sharp. Also cool to be able to use it to track aircraft with ADS-B.

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.

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,

Maybe nice for some other frequencies, but doesn't want to pick up anything around 868mhz, so avoid if you're using it for FLARM etc.
