# ==== sdr.hu listing ====
# If you want your ham receiver to be listed publicly on sdr.hu, then take the following steps:
# 1. Register at: http://sdr.hu/register
# 2. You will get an unique key by email. Copy it and paste here:
sdrhu_key = ""
# 3. Set this setting to True to enable listing:
sdrhu_public_listing = False

# ==== DSP/RX settings ====
fft_fps=9
fft_size=4096 #Should be power of 2
fft_voverlap_factor=0.3 #If fft_voverlap_factor is above 0, multiple FFTs will be used for creating a line on the diagram.

fft_compression="adpcm" #valid values: "adpcm", "none"

digimodes_enable=True #Decoding digimodes come with higher CPU usage.

"""
Note: if you experience audio underruns while CPU usage is 100%, you can: 
- decrease `samp_rate`,
- set `fft_voverlap_factor` to 0,
- decrease `fft_fps` and `fft_size`,
- limit the number of users by decreasing `max_clients`.

# ==== Misc settings ====

client_audio_buffer_size = 5
#increasing client_audio_buffer_size will:
# - also increase the latency
# - decrease the chance of audio underruns

iq_port_range = [4950, 4960] #TCP port for range ncat to listen on. It will send I/Q data over its connections, for internal use in OpenWebRX. It is only accessible from the localhost by default.

# ==== Color themes ====

#A guide is available to help you set these values: https://github.com/simonyiszk/openwebrx/wiki/Calibrating-waterfall-display-levels

### default theme by teejez:
waterfall_colors = [0x000000ff,0x0000ffff,0x00ffffff,0x00ff00ff,0xffff00ff,0xff0000ff,0xff00ffff,0xffffffff]
waterfall_min_level = -88 #in dB
waterfall_max_level = -20
waterfall_auto_level_margin = (5, 40)
### old theme by HA7ILM:
#waterfall_colors = "[0x000000ff,0x2e6893ff, 0x69a5d0ff, 0x214b69ff, 0x9dc4e0ff,  0xfff775ff, 0xff8a8aff, 0xb20000ff]"
#waterfall_min_level = -115 #in dB
#waterfall_max_level = 0
#waterfall_auto_level_margin = (20, 30)
##For the old colors, you might also want to set [fft_voverlap_factor] to 0.

#Note: When the auto waterfall level button is clicked, the following happens:
#   [waterfall_min_level] = [current_min_power_level] - [waterfall_auto_level_margin[0]]
#   [waterfall_max_level] = [current_max_power_level] + [waterfall_auto_level_margin[1]]
#
#   ___|____________________________________|____________________________________|____________________________________|___> signal power
#        \_waterfall_auto_level_margin[0]_/ |__ current_min_power_level          | \_waterfall_auto_level_margin[1]_/
#                                                      current_max_power_level __|

# === Experimental settings ===
#Warning! The settings below are very experimental.
csdr_dynamic_bufsize = False # This allows you to change the buffering mode of csdr.
csdr_print_bufsizes = False  # This prints the buffer sizes used for csdr processes.
csdr_through = False # Setting this True will print out how much data is going into the DSP chains.

nmux_memory = 50 #in megabytes. This sets the approximate size of the circular buffer used by nmux.
