Is anyone working on Reticulum firmware for this?

I think it could be good foundation for a Reticulum walkie talkie.

Why would voice over 2.4GHz LoRa not make sense? Encrypted voice over ISM global licence-free band that doesn't break any laws makes sense to me.

yeha i'm confused too, zenith party line has codec2, it's working fine for me over 3.5kbps or something ridiculous like that. But maybe i'm missing something
