| 2012-10-07 | tuner_r820t: improve tuning accuracy, allow freq correction | Steve Markgraf | |
| We now use Hz instead of KHz for calculating the PLL parameters, and use the actual crystal frequency in Hz, which allows to correct the frequency error in ppm. Signed-off-by: Steve Markgraf <steve@steve-m.de> | |||
| 2012-09-13 | add support for direct sampling mode | Steve 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> | |||
