We keep hitting this bandwidth wall. I say we should just ignore it. We are
never gonna get a change if we don't show the need for it.

I note that at the advertised bit rates, the OBW

exceed US Regulations for 70cm. However, the chip used, is also claimed to
support 33cm.
I am interested in the new packet protocol proposed by the project. Even at
a lower bps on 70cm (for the US), and full rate at 33cm, this has real
potential for mid-tier data communications.

It's designed for "access", not backbone, and not designed for H24 use.
Its is 100% open-source.
Do not hesitate to ask me questions about it.
I hope it will interest some people here.
