# Number of SDRs or SDR Connection Threads to use

# If SDR type is set to RTLSDR above, then this number is the number of individual RTLSDRs
# that will be used, eith each RTLSDR allocated a scan or decode task.
# If more than one RTLSDR is in use, multiple [sdr_X] sections must be populated below

# If SDR type is either KA9Q or SpyServer, this defines the maximum number of parallel
# decoding/scan tasks. On a RPi 4, ~5 tasks are possible.

# Network SDR Connection Details

# Device Index / Serial
#	If using a single RTLSDR, set this value to 0
#	If using multiple SDRs, you MUST allocate each SDR a unique serial number using rtl_eeprom
#   The serial number must NOT be 00000000 or 00000001, as this causes big confusion to the rtl utilities.
#	i.e. to set the serial number of a (single) connected RTLSDR: rtl_eeprom -s 00000002
#	Then set the device_idx below to 00000002, and repeat for the other [sdr_n] sections below
#
#   For the special case when auto_rx is used entirely with a JSON-via-UDP input, set the below to TCP001
#   This will bypass all RTLSDR checks and allow auto_rx to continue running.

# SDR Gain Setting
#   Gain settings can generally range between 0dB and 40dB depending on the tuner in use.

# US: 
#   Some areas have transitioned to the 400.05 - 406 MHz band, so try 400.05 - 406
#   Some areas are still using ~1680 MHz sondes, which use channels of 1676, 1678, 1680 and 1682 MHz (Thanks Tory!)
#   Example only_scan for these sondes: [1676.0, 1678.0, 1680.0, 1682.0]
#   In these areas I suggest using the only_scan feature below instead of using the peak-detect search.
#	You may also need to apply a small offset to the frequency for decoding reliability (i.e. 1676.025 MHz) as 
#	the sondes are often off-frequency. For now, check in something like GQRX to get an idea of what offset is required.

########################
# Settings for uploading to radiosondy.info
#
# IMPORTANT APRS NOTE
#
# As of auto_rx version 1.5.10, we are limiting APRS output to only radiosondy.info,
# and only on the non-forwarding port. 
# This decision was not made lightly, and is a result of the considerable amount of
# non-amateur traffic that radiosonde flights are causing within the APRS-IS network.
# Until some form of common format can be agreed to amongst the developers of *all* 
# radiosonde tracking software to enable radiosonde telemetry to be de-duped, 
# I have decided to help reduce the impact on the wider APRS-IS network by restricting 
# the allowed servers and ports.
# If you are using another APRS-IS server that *does not* forward to the wider APRS-IS
# network and want it allowed, then please raise an issue at
# https://github.com/projecthorus/radiosonde_auto_rx/issues
#
# You are of course free to fork and modify this codebase as you wish, but please be aware
# that this goes against the wishes of the radiosonde_auto_rx developers to not be part
# of the bigger problem of APRS-IS congestion. 
# As of 2022-03-01, radiosonde traffic has been filtered from aprs.fi, so even if you do
# modify the code, you still won't see sondes on that map.
# APRS-IS is a *shared resource*, intended for the use of all amateur radio operators, and 
# for many years we have been treating it as a playground to dump large amounts of non-amateur
# traffic into, so we can see weather balloons on a map. 
# Instead of congesting this shared resource with this non-amateur traffic, we should instead
# be moving to using databases and sites specialised for this purpose, for example sondehub.org
