This is the main problem with ALOHA-like TX scheduling, or lack thereof.[1]

We're using slow, outdated Bell 202 modems to transmit data on 2 meters. 
There are better ways, and better technology to do so.

Take, for instance, the proliferation of "sub-1GHz" digital radio modem 
chips from TI, ST, NXP, Silicon Labs, ON semi, etc. Many of them can 
transmit in most amateur bands between 2m and 928MHz.

Let's get out of the 2m packet mindset and on to higher data rate 
networks on 1.25m, 70cm, and 33cm!

I've got a small back-burner project which I hope to share when I get 
some time. It is along these lines.
