What happened?

When configuring the FSK channel for AS923 it is some 40MHz higher than it should be.

What did you expect?

FSK channel is on the correct frequency

Steps to reproduce this issue

Configuration

  # Region.
  #
  # Please refer to the LoRaWAN Regional Parameters specification
  # for the complete list of common region names.
  region="AS923"

  # Minimal frequency (Hz).
  frequency_min=920000000

  # Maximum frequency (Hz).
  frequency_max=923400000

  # Concentrator configuration.
  #
  # This section contains the configuration for the SX1301 concentrator chips.
  # Example:
   [[backend.basic_station.concentrators]]

     # Multi-SF channel configuration.
     [backend.basic_station.concentrators.multi_sf]

     # Frequencies (Hz).
     frequencies=[
       923200000,
       923400000,
       922200000,
       922400000,
       922600000,
       922800000,
       923000000,
       922000000,
     ]

     # LoRa STD channel.
     [backend.basic_station.concentrators.lora_std]

     # Frequency (Hz).
     frequency=922100000

     # Bandwidth (Hz).
     bandwidth=250000

     # Spreading factor.
     spreading_factor=7

     # FSK channel.
     [backend.basic_station.concentrators.fsk]

     # Frequency (Hz).
     frequency=921800000


Steps:

  1. Implement above configuration file
  2. Observe channel map
