[HamGateNY] Proposed WWconvers Channel Scheme

Sat Nov 28 20:58:39 EST 2020

Hi Charles,

Although I've read your past few emails in the thread, I, like Joe, am new to the WW convers concept and have a question. Forgive me...

So I understand the purpose - logical allocation, assignment, maximal utilization of space/bandwidth, etc. But in reality/technical functionality, is this "channelizing" a schema that works as you said like AIM or IRC in the sense that it is literally a form of packetized, tagged or multiplexing sort of thing, or is it an RF/split spectrum sort of concept?

In other words, as we discuss both RF and non-RF mediums here, is this something that would just multiplex (channelize) data over a single RF frequency (sort of like DMR or simar) or would it require a spread spectrum of multiple subfrequencies?

I assume the former as you say this is over two decades old and already in practice and I doubt the practicality of finding 32768 different frequencies. :) I am just trying to "picture" it as conversations or channel data jump between one medium (internet/TCP/IP traffic) to another (RF) and back across the network...

Sort of like Brandmeister or a channelized EchoLink, but the AMPRnet version?

Regards,

AJM
