2013-01-29lib: remove "e.g. hama nano" from the default device descriptionSteve Markgraf
This caused some confusion... Signed-off-by: Steve Markgraf <steve@steve-m.de>

2013-01-16lib: enable standby mode of e4k and r820t on exitSteve Markgraf
Since the R820T is a power hog and gets quite hot, this makes sense, especially when being battery- powered. Signed-off-by: Steve Markgraf <steve@steve-m.de>

2012-09-13add support for direct sampling modeSteve Markgraf
This commit adds the function rtlsdr_set_direct_sampling() which can be used to enable/disable a mode where the RTL2832 acts as a direct sampling receiver. This mode disables the tuner, and by attaching a long wire, or better, a 50Ω to 200Ω transformer and a lowpass- filter to the In-phase ADC input (pin 1 or 2 of the RTL2832, whereas pin 1 is at the molded dot) it is possible to listen to shortwave radio stations. The coupling capacitors can be left in place, but for better results they should be removed. Tuning in this mode is done with the DDC, and since the ADC samples with 28.8 MHz, tuning is possible from 0 to 28.8 MHz. Signed-off-by: Steve Markgraf <steve@steve-m.de>

2012-07-08apply frequency correction value on the xtal clock directlyDimitri Stolnikov
by using this approach both, the tuning frequency and the sample rate should be corrected at the same time.
