Hello,

Has someone managed to get the free upgrade from the paperback version to the latest Kindle version ?
I sent an email to Amazon but they said that I can't get the free upgrade from the paperback version to the latest Kindlke version.

Hello, So ladder line + transformer is better than normal wire + balun ? How does the RTL-SDR "Portable Antenna Set with 7M Long Wire and Telescopic Whip" perform in HF ? Does "Matching SMA Adapter" mean that there's some sort of balun or adapter in the sma connexion ? Thanks again for your help, Ja...

Hello,

Thanks for the photos. What receiver are you using for HF, how is the antenna connected to it (directly or with a balun) ?
What sort of distance can you receive ?

Thanks for your help.

Hello, Thanks for the new answers. In the end, I bought an Airspy mini and a spyverter r2. For the moment, I haven't got a suitable antenna for HF.

What is the best way to listen to HF when you live in a town, with very little outside space for an ante...

Hello, Thanks for your quick answer. For the price, I think that I'll stay with the RTLSDR V3 dongle. More bandwdith would be nice but is it worth the price of 5 RTLSDR V3 dongles ?! As I've already said, I'm having lots of fun with my cheap dongle (AIS, ACARS, ADS-B, NOAA, Inmarsat, RTL_433, weathe...

Hello, In a nutshell, what does an 'expensive' sdr do compared to a 'cheap' one? Does it receive weaker signals, is the sound quality better. For example, on the hdsdr website, it says don't expect wonders from the rtlsdr v3 dongle (http://www.hdsdr.de/hardware.html). I'm using the rtlsdr v3 dongle,...
