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
