Ive noticed this with several of the rtl sdr's ive used in the past. In contrast, the Planar Disk is almost free and it performs quite well in an indoor setting. Just because an antenna 'is sold' does not mean its good or even marginal.

Please verify your dongle is working with a good antenna before complaining that you cannot receive something. Here is a great, broadband Planar Disk Antenna that outperforms most commercial antennas of similar size for under $65-75 and can be built in a half hour or less by beginners with less than $10 in parts. See our wiki with tutorials and other resources including a Quick Start page to verify your dongle works. The rtl-sdr project page Source of the rtl-sdr driver software and hub for its continued development. Resources - Please read this first - before posting!

Max sample rate: 3.2 MS/s (2.6 MS/s in practice).

Frequency range : 24 - >1760 MHz (100 KHz - 24 MHz in direct sampling mode).

Typical specs (some depend on specific tuner): All rtl-sdr compatible devices employ the RTL2832U as an ADC and USB controller, but different RF tuners may be used. 'rtl-sdr' is a generic term for cheap USB digital TV (DVB-T) receivers that use the Realtek RTL2832U chipset, which can function as general purpose software defined radios (receive only). While originally dedicated just to the rtl-sdr project, relevant legal content related to general SDR, RF and similar projects is also welcomed.įeel free to ask questions but please check the wiki first.
