> …all the nodes on the same channel significantly impacts latency with more handshaking, which affects voip.

> Ideal approach is to dtdLink all the nodes together and put them all on different channels.

> The 'mesh' per se is not at the RF level, rather above that at the IP level.

>  …putting everything on the same RF channel will have reduced performance and won't scale. (…won’t scale to anywhere near a dozen Channel -2 omnis! An expensive lesson.)

> The dozen:

> WA8APB Channel -2 Omni 
> KA8ZKR Channel -2 Omni 
> N8NQH Bellbrook Channel -2 omni 
> N8NGH S Xenia Channel -2 omni

> Notes:
> [1] 2.4 omni at KAS on a line between MVHS and WA8APB AGM2s
> 
> [2] Brings cross-mesh link up from 10 MHz SISO to 20 MHz MIMO
>     3.4 omni at N8NQH Bellbrook on line between MVHS & W Xenia.
> 
> [3] Helps keep its 2.4 RF out of DARA omni and KAS nodes
>     Should get our nodes below the tank obstruction light
>     
> [4] Radiation to WA8APB NSM5 probably blocked by tower leg
