Ok, I used the details in that forum post (https://forum.mikrotik.com/viewtopic.php?f=2&t=155803) with the MikroTik terminal on the gateway to set the channel plan to ‘custom’ and load up the TTN AU915 frequencies.
My channels now look like this:
Is that right?
Before this I edited my Ursalink UC1122 channel plan to match what I think it should be for AU915, and it stopped communicating (which is what I expected as there was no longer any overlap in frequencies).
After this, the Ursalink node appeared again. But, it’s supposed to be sending every minute, and I’m not seeing that. I’m only seeing occasional messages. Will look deeper.
