I remember getting one of those when I was 10 or 11. First generation. All excited to finally have a computer. But I couldn't leave it on for more than an hour or two before it would just crash because it had overheated. Too frustrating to use. We sent it back before the necessary 10 days had passed.
I was sad.
Later (within the year? I don't remember) I got a Vic-20; a couple of years later, a Commodore 64. Then, in college, a Commodore 128. Those guys worked much better for me than the Sinclair ZX ever did.
So, it is tempting to resurrect Technocrat.net now that Slashdot stinks worse than the last two times I shut down technocrat.net
If you remember, we didn't get very many readers. We didn't get them because not enough people submitted usable articles.
I know that I can do it technically, and I have the server, and Cloudflare should be able to help me handle the load. But if it is like last time, and my wife observes that I'm talking to the same dozen guys all of the time, it's not going to work.
What do you think?
You could do this using FRS walkie talkies, as long as they have microphone and earphone connections. Or analog telephones. It's been tested multiple times on ham FM walkie talkies. Anything that carries voice should work. The bandwidth is only 1.25 kHz and I think the low end starts at about 700 Hz.
MOS is only for people who want to pay a lot of money. Of the automated processes, the one available to us isn't validated for less than 4K bps codecs.
It would be a great improvement to MOS if there was an open version of POQLA. But the actual customer base for the codec have never even heard of MOS and thus we aren't volunteering to write that. The folks who want to put it in expensive government support systems yet aren't willing to help with testing don't get our sympathy.
We avoid some techniques that would make the noise performance worse. The HF version of the codec doesn't vector quantitize, and doesn't do any delta coding between frames. The current FEC is Golay and we are investigating low-density parity codes.
There is a lot yet unheard about the Ratheon codec, regarding its actual noise performance and how well the listener can distinguish different speakers.
