    On a Conduit, can the EU868 channel plan be configured to offer one FSK channel running at DR7 (50Kbps)?

    If so, how to do this? I assume it will require a custom configuration of the layout of the channel plan that will be propagated to the network.

    Packet forwarder allows configuration of an FSK channel.

    		"chan_FSK": {
    			"bandwidth": 125000,
    			"datarate": 50000,
    			"enable": true,
    			"if": 300000,
    			"radio": 1
    		},
    

    For the EU868 channel plan 868.8 MHz is defined of FSK in network server and packet forwarder modes using the UI to configure. The above configuration is used by packet forwarder MANUAL mode.

    We are not using packet forwarder mode. We are running some application code on the Conduit that connects to our own cloud services.

    Is there a config file that sets the radio channel plan in general for each region setting?

    https://192.168.2.1/api/loraNetwork?method=PUT&data={“lora”:{“frequencyOffsetDR7”: 300000}}

    Frequency is offset from 868.5 MHz, offset is limited to ~ +/- 500K

    Restart lora network server.
    Save and restart the Conduit to persist.

    Does this knock out one of the other LoRa mode channels, or is there already spare capacity for the EU868 setup?

    Is there already another LoRa channel set up on that center?

    The planning of the network seems to be very … opaque.
    I am hitting network capacity limits with EU868 due to the 1% airtime.

    Given that the EU868 spec does not mandate the channel plan directly in the way that the US915 plan does, it would be good to know the actual, exact channel plan that the Conduit it set up to offer when in EU868 mode, so I can compare that (and any additions/modifications) to the EU868 bands, airtime limits, and plan for the capacity that is needed.

    I would like to be able to be able to know, see, and modify exactly which centers, BW’s, DR’s, and modes (LoRa vs FSK) are being offered. By either the UI setup or by editing of a config file.

    Channels for DR6 and DR7 are configured separately

    Conduit AEP: Convert to Basic Packet Forwarder

    The Sx1301 allows 8 Multi-SF (SF7-12) channels at 125 KHz, one LoRa channel with fixed SF/BW and one FSK channel.
    https://www.semtech.com/uploads/documents/sx1301.pdf

    In packet forwarder mode the full configuration is available via MANUAL configuration.

    In network server mode see the LoRaWAN Gateways page.
    Choose the detail option from the gateway list.

    Also info available through API, see packetForwarders section.

    Multiple Conduits can also be networked to provide more downlink capability
