+# In order to use an HPSDR radio, you must install hpsdrconnector from https://github.com/jancona/hpsdrconnector
+# These are the command line options available:
+#  --frequency uint
+#    	Tune to specified frequency in Hz (default 7100000)
+#  --gain uint
+#    	LNA gain between 0 (-12dB) and 60 (48dB) (default 20)
+#   --radio string
+#     	IP address of radio (default use first radio discovered)
+#   --samplerate uint
+#     	Use the specified samplerate: one of 48000, 96000, 192000, 384000 (default 96000)
+#
+# If you omit `remote` from config_webrx.py, hpsdrconnector will use the HPSDR discovery protocol
+# to find radios on your local network and will connect to the first radio it discovered.
