#   0:  Realtek, RTL2838UHIDIR, SN: NOAA_001 (or ADSB_001)
#
# Supported gain values (29): 0.0 0.9 1.4 2.7 ...
# [R82XX] PLL not locked!
# Sampling at 2048000 S/s.
# NO EES, NO OVERRUN

# Check next NOAA pass
# First, update TLE data:

# Find next NOAA pass (manual test):
# NOAA-15: 137.620 MHz
# NOAA-18: 137.9125 MHz
# NOAA-19: 137.100 MHz

# View image:
# Look for horizontal lines indicating APT signal
# If image is mostly noise, check antenna and gain
