【スマホを広帯域受信機にする】amazon Fire HDを広帯域無線受信機に魔活用してみた /Androidスマホでも使えます

This is a how-to video on how to install a USB tuner and free SDR receiving software on an Android device, turning it into an ultra-wideband receiver. To run the Android version of the SDR software, you'll need a USB tuner, antenna, and a dedicated USB OTG cable. You can also install and run an SDR on a smartphone, but the small screen makes it difficult to use. I switched to an Amazon Fire HD 10 and found that operability improved dramatically, so I included it in this video. You can use a USB tuner equipped with an RTL2832 IC chip, which can be purchased for less than 2,000 yen, but if you have the budget, we recommend the "RTL-SDR.COM V3" USB tuner, which has significantly better frequency selection performance. Note 1) When the source is set to RTL-SDR in RFAnalyzer, the receiving frequency is fixed at 28 MHz or higher, so AM broadcasts and shortwave (HF) bands cannot be received. A separate frequency converter is required. Note 2) There are imitations of RTL-SDR.COM (products without the .COM prefix), so please be careful when purchasing. Detailed operating instructions are also listed on this channel's web page, so please refer to it as necessary. https://falconblog.org/android-sdr-in...
