RTL-SDR V3..RTL-SDR V3和V4都是业余无线电爱好者常用的软件定义无线电接收器。一般来说,V4相比V3有一些改进,比如更好的传感器和低噪声放大器。因此,如果预算充足,我建议选择V4,因为它在性能上会稍微优于

我们很高兴地宣布,我们的新RTL-SDR BLOG V4接收器的第一个版本是基于R828D调谐器芯片。带有天线组的V4接收器的价格为39.95美元,仅接收器的价格为29.95美元,包括免费送货到大多数国家。 目前我们只从我们在中国的仓库发货这个型号,最初的生产批量很小,所以我们的库存有限。然而,现在我们已经确认,第一批小批量V4的生...
Almost all software (Confirmed to work on SatDump, SDR#, SDR-Console V3, SDR++, Welle.io, RTL1090v2) Most programs now come with an updated driver that works with the V4 (e.g. SDR#, SDR++ and SDR-Console V3 have all been updated with their latest versions). However the software y...
RTL-SDR Blog V4设计的核心变化是从R860调谐器芯片到R828D调谐器芯片的变化。R828D以前是一个更昂贵的芯片,然而,随着R860在今年年初生效的巨大价格上涨,我们决定利用现有的R828D库存,现在比R860便宜。 R828D与R820/R860非常相似,并共享许多相同的电路。然而,它不是只有一个输入,而是有三个可切换的输入。我们将这...

We’ll admit to not fully knowing what [Jay Doscher] has planned for the pair of RTL-SDR Blog V4 software defined radios (SDRs) that are enclosed in theslick 3D printed enclosure he’s designed. But when has that ever stopped us from appreciating a nice design when we see one?
