3) Hack to force the bias tee to always be on by setting the unused IR endpoint bit to 0 in the EEPROM. Example to force the BT to be always ON "rtl_eeprom -b 1", to remove forced BT "rtl_eeprom -b 0" 3) Hack to force the bias tee to always be on by setting the unused IR endpoint bit to 0 in the EEPROM.

4) Repurposed "offset tuning" to toggle bias tee ON/OFF. We can now use the "offset tuning" button in SDR# and other programs to toggle the bias tee if there is no specific button in the GUI. 4) Repurposed "offset tuning" to toggle bias tee ON/OFF.

5) Support for future R828D based dongles. 5) Support added for R828D RTL-SDR Blog V4 based dongles.
6) Auto direct sampling. Will automatically change to direct sampling mode when the frequency is below 28.8 MHz. Will change back when the frequency is above 28.8 MHz again. 6) Auto direct sampling. For R820T/R860 dongles the code will automatically change to direct sampling mode when the frequency is below 28.8 MHz. Will change back when the frequency is above 28.8 MHz again.
BIAS TEE NOTE: Always take care that you do not enable the bias tee when the device is connected to a short circuited antenna unless there is an inline LNA. However. if you did by accident, don't worry as the circuit is dually protected with a self-resetting thermal fuse and built in protection on the LDO. Just try not to short it out for days at a time, otherwise you could eventually degrade the thermal fuse.
