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.

There is a video of the codec vs. SSB on the same radio link here. You can also take any radio links you have at hand and run the FreeDV program. This is an evening project to set up without a business case, and at least some companies appreciate people who take the initiative to do this sort of thing.

Comment Re:1200 bits/s, not bauds. (Score 1) 37

Sorry. When I say "1200 Baud", I am in general thinking of the TAPR TNC 2, which was never built for voice but can do it, to a degree, with this codec. It's sort of a Bell 212 modem on half-duplex radio. There were many commercial products based on the TNC 2 design and many hams have them on hand. It's a good demo to put speech through a pair of them, not really practical because the latency is high.

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.

Oh, definitely, cramming isn't a particularly good strategy, especially in the long term. My point is just that (particularly for people who have conditions for which they are prescribed; but apparently the general population as well to some degree) performance enhancing drugs are simply performance enhancing.

People who have blatantly shot study habits and/or sleep schedules need drugs to function; because they are pushing themselves well beyond sensible parameters; but it's entirely possible to take a sensible approach to sleep and study and just make it a bit better with the extra focus and alertness that drugs can provide. You have to be careful; because the greater ability to push yourself makes it easier to fall into bad habits and (at least for a bit) get away with it; but if you are careful, there isn't anything magically pathological about drug-aided activity.

It's worse than a non-sequitur:

Let's play EC101 for a second here:

1. Not enough students are persuing 'STEM' education.

2. Hypothesis: 'STEM' education needs to be improved, to improve retention and attraction and/or the rewards of pursuing 'STEM' education need to be more visible, greater, or both.

3. Ergo, we should issue more H-1B visas in order to lower the real wages for workers in 'STEM' fields and thus incentivize more students to study the (even if rewarding, quite challenging) 'STEM' subjects!

A non-sequitur would be downright sensible by comparison. At least disconnected statements tend to not be internally contradictory...

If you are having difficulty recruiting students for a subject, why would you possibly want to reduce the rewards for studying a subject? That's the opposite of what you want to do. Now, admittedly, some non-STEM students or STEM-abandoning students are motivated more by shitty teaching or other similar factors than they are by future job prospects; but unless you want to abandon basically all theories of human motivation underlying vaguely capitalist economies, you have to admit that expected payoff is sort of a major factor in whether to stick with hard math or go and do something else.

This one strikes me as similar to the (also surprisingly common and equally absurd; but self-interested) "We can't attract enough good talent, also wages are too high!" whining from employers. Hey, dumbass, supply curves, no? If you can't attract good talent, how can you also be paying too much? Unless your work environment is brutally fucked on various social levels, if you were overpaying, talent would be knocking down the door to come join you...

Clearly IE, the popular closed source browser, ,is against anonymity. Who knows this for sure, the country with the code .ie - I feel dumb for not knowing earlier.

I strongly doubt that there is actually a connection here, rather than some pandering moron attempting to secure the Irish values voter/authoritarian 'security' freak vote; but MS (and most multinationals doing business in the EU) magically book enormous portions of the proceeds in Ireland, rather than countries with the actual customers and higher taxes...
