# Receive Frequency (Hz)
# The normal receive frequency used by Project Horus is 443.5 MHz
RXFREQ=443500000

# Receiver Gain. Set this to 0 to use automatic gain control, otherwise if running a
# preamplifier, you may want to experiment with lower gain settings to optimize
# your receiver setup.
# You can find what gain range is valid for your RTLSDR by running: rtl_test
# A very rough figure that may work if you are running a preamp with ~20 dB gain is
# 32.8 - your performance may vary!

# Bias Tee Enable (1) or Disable (0)
# Enable this is you are intending on powering a preamplifer via coax from your RTLSDR

# 9600 baud, 100x oversampling
# 4800 baud, 200x oversampling
