Product description

Quickstart Guide: rtl-sdr.com/QSG
V3 Features Guide: rtl-sdr.com/V3
Antenna Guide: rtl-sdr.com/DIPOLE

This is an RTL-SDR blog software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz (2.4 MHz stable) of bandwidth. (HF works in direct sampling mode). Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works on Windows, OSX, Linux, Android and computers like the Raspberry Pi.

Great for many applications including general radio scanning, air traffic control, public safety, ADS-B aircraft radar, ACARS, trunked radio, P25/MotoTRBO digital voice, POCSAG, weather balloons, APRS, NOAA APT/Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a ham radio.

Comes with a multi-purpose dipole antenna kit which is perfect for beginners. The short antennas are great for ADS-B, and the longer antennas work well at lower frequencies. When used in a v-dipole configuration the antenna works well for 137 MHz weather satellites and the ISS. Use in a vertical configuration for terrestrial signals. The two mounts and 3m of RG174 cable allow you to easily mount the antenna outdoors.

This model has several improvements over other brands. It uses the improved R820T2 tuner, a 1PPM TCXO, better components, a redesigned lower noise PCB, cooling improvements, extra ESD protection and an SMA F connector. It also has a software activatable bias-tee for powering LNA's and active antennas. Full info available on the improvements at goo.gl/MD12bD

For enabling HF reception below 24 MHz please see the V3 features guide: rtl-sdr.com/v3 and please feel free to contact us via Amazon messaging for technical support - we're happy to help.

<セット内容など>

短波も聞きたかったので、このドングルを買うことにしました。
単体で買うかこのセットにするか最後まで迷いましたが、SMAコネクターやケーブルも別に買うと結構高いので、結局こちらを選択。プラス千円というのはコスパ的には微妙な線だと思います。
アンテナやケーブルはとりあえず無いよりマシなレベル。かなりシャビーです。

<温度の上昇>

外気温29℃で約30分稼働後、ケース温度は45℃になりました(それ以上にはなりませんでした)。
浅田飴の空き缶にのせて風を当ててやると35℃以下で安定しました。

<ソフトのインストール>

紙のマニュアルはついておらず、URLを書いた紙が1枚だけ。
サイトは英語ですが、わかりやすいです。Google翻訳を使えば違和感のない日本語に変換してくれます。

受信ソフトは以下のものを試しました。

・SDR-Sharp (Windows版)
メーカーのサイトではこれが一番おすすめになっています。
Zadiag USBドライバーもインストールする必要がありますが、ダウンロードサイトに問題があったようで最初うまくいきませんでしたが、ばらくして、再挑戦するとダウンロードできました。
あとはすんなり動きました。

中波帯: NHKなど電波の強い局はとりあえず受信できました。ただし感度はあまりよくないです。
HF帯: 北京方法、平壌放送など電波の強い局はクリアに入りました。アマチュア無線も近所の局はなんとか。
(中波帯、HF帯を聞くためには、ソフトの設定をダイレクトサンプリング用に変える必要があります。この設定にすると28MHzまでしか聞けないので、VHFを聞く場合は設定をデフォルトに戻す必要があります)

FM: いちおう実用レベル。ただしステレオだとノイズが結構多いです。アンテナケーブル自体も結構電波(雑音)を拾うので、配線ルートに工夫が必要です。
VHF: 航空無線はを中華ラジオ(XHDATA D-808)と遜色ないレベルで聞けました。

・Gqrx (MAC版)
インストールは問題なく終わりましたが、まったく音がでないので困りました。
サイトの説明をよく読むと、Receiver OptionのModeのところがデフォルトで”Demand off"になっているのが原因と判明。そこをAMとかWFMに切り替えると音が出るようになりました。

こちらも中波、HF、FM、VHF問題なく受信できました。
中波とHFの受信では、ダイレクトサンプリング用の設定を行う必要があります。
Configure I/O devicesのアイコンをクリック
→Device stringに "rtl=0, direct_samp=2" と入れる。(direct_samp=3でも動きました) 
こうするとDeviceがOtherになるが問題なく動く。

HFの受信では、サンプリング周波数をいろいろ選べるので、SDR Sharpよりも調整がしやすいと思います。

・RF Analyzer (Andoroid版)
Rtl-sdr ドライバーというソフトもインストールが必要です。
Andoroid4.4.2のタブレットと7.0の古いスマフォでトライ。
ダイレクトサンプリングには対応していないためHF以下は聞けませんが、FM以上は問題なく聞けました。

・Radio receiver (Chromebookアプリ)
FM専用です。操作性がふつうのラジオと一番近く使いやすいと思います。
