;# Please note that the new RTL-SDR Blog V3 dongles ship a < 1 PPM
;# temperature compensated oscillator (TCXO), which is well suited for GNSS
;# signal processing, and a 4.5 V powered bias-tee to feed an active antenna.
;# Whether the bias-tee is turned off before reception depends on which version
;# of gr-osmosdr was used when compiling GNSS-SDR. With an old version
;# (for example, v0.1.4-8), the utility rtl_biast may be used to switch the
;# bias-tee, and then call gnss-sdr.
;# See https://github.com/rtlsdrblog/rtl_biast
;# After reception the bias-tee is switched off automatically by the program.
;# With newer versions of gr-osmosdr (>= 0.1.4-13), the bias-tee can be
;# activated by uncommenting the following line:
SignalSource.osmosdr_args=rtl,bias=1
