add support for direct sampling mode

2012-09-13T19:53:51Z

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

return RTLSDR_TUNER_UNKNOWN (0) on failure of rtlsdr_get_tuner_type

apply frequency correction value on the xtal clock directly

2012-07-08T13:52:59Z

by using this approach both, the tuning frequency and the sample rate should be corrected at the same time.

disable DAGC by default, add control function

This adds rtlsdr_set_agc_mode() to enable/disable it. Thanks to Leif Asbrink for finding this setting. Signed-off-by: Steve Markgraf
