Public Channel Removal Stops Node From Working

[W1LMS]

Hey @MtTopGuy, I had the same issue. Did not see your thread until now. I posted the same issue yesterday, then stumbled across the solution on this page, even though I had been over this page many times before. It says:

@W1LMS

While you can have a different PRIMARY channel and communicate over SECONDARY channels with the same Name & PSK, a hash of the PRIMARY channel’s name sets the LoRa frequency slot, which determines the actual frequency you are transmitting on in the band. To ensure devices with different PRIMARY channel name transmit on the same frequency, you must explicitly set the LoRa frequency slot.

Hope that helps.
