    Unit works well in the shortwave/HF band and similar at other freqs, you don't use direct sampling as it has a HF upconverter on board, you'll need to use the blog v4 driver which makes HF tuning seamless, just tune to freq you need. Tested with linux and GQRX. Of course: the antenna you connect is everything, poor antenna feed will only result in disappointment, a long wire outside and up high will greatly improve things. But I'm sure you heard this before... Do make sure you buy a legit unit.

    Im Vergleich zu den "einfachen" RTL-Dongles ein Quantensprung. Ich nutze den Dongle an einem Einplatinencomputer mit Debian und dem rtl_tcp-Paket als universellen Netzwerkempfänger. Mit der entsprechenden Software und korrekten Einstellungen lassen sich starke AM-Signale, UKW und DAB+ sehr gut empfangen. Die Lieferzeit war mit 2 Wochen aus China deutlich kürzer als angegeben.

    The sma connector is female so need a male plug from to terminate the antenna

    Better than expected.

    I use it as a ASD-B receiver with a raspberry pi and it has very good sensitivity. The integrated EMI filter works fine so don't need the external filter i have. The only concern is that the receiver is getting hot and I have to do something about that because it is placed in a box where the sun sees it all day. For flightradar24 radarbox and related applications you have to install the appropriate drivers from rtl-sdr site. It is better than expected. I recommend it.

    RTL-SDR dongle. 100% happy with my purchase..

    Purchased two RTL-SDR dongles, very good value for money, excellent reviews. Will be buying another two soon as I mainly listen to P25 and TETRA trunking systems.

    SDR works as advertised.

    SDR works as advertised. It is as easy to use as the V3 version but does a better job at HF frequencies. However, the sensitivity is a few dB lower when using the internal upconverter as opposed to using a NooElec standalone upconverter. Still very usable.

    The best RTL-SDR

    I bought this device for a specific receiving task. I wanted to use it with the AirSpy SDR# software and the RTL_433 plugin from GitHub. I had it up and running within a couple of hours and was able to log a dozen or so low-power 433 MHz wireless devices by the next day. All this with a short indoor antenna, The RTL-SDR BLOG V4 is quite sensitive on UHF frequencies. The value proposition lies not just in the quality of this RT:L-SDR implementation, but also in the wealth of free software for decoding a myriad of radio signals by RTL-based devices.
