Almost three weeks to reach port from China ... transportation ... China Post! The CD ROM is unreadable and appears to be empty? Fortunately, the seller was very correct and quickly sent the file by email. The sensitivity is very good and the use of TV software is easy. It is a R820T RTL2832 that seems to work from the top of the HF band to over 1.1GHz therefore interesting for the reception of 1090MHz with rtl1090 is the use I made of it. Sdrsharp I use for radio reception ... Overall very positive note!
