Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
1. It gives you actual live conversations with all the mistakes and alterations. Not everyone uses computer generated CW. In fact, most brass pounders dislike it because it's boring to listen to and dry to copy.
2. There are sanctioned CW events all the time... QSO parties, commemorative stations and even at the beginning of next month there are straight key nights where people put the paddles away and break out the straight key.
3. I'm going to assume the end goal is to put this listening to live feeds anyways. You should work toward that goal now as then you can write code to compensate for QRM and QRN/fading.
Having people feed you 'tapes' won't accomplish your goal. You need to have it work with the real source.
Think of how long it has taken to get GPS based ILS put in place and approved even tho the practices and technologies have been around for decades.
But think of the stream coming off the satellite as one big pipe. So that's a known cost based on overall usage. But then it's routed on the ground different ways. Since GPRS/GSM/UMTS/LTE/etc... is a mobile protocol, you're now having to route to another network or if you're the provider having to invest in infrastructure to unencapsulate all this data and turn it back into IP as opposed to WiFi which is already IP. Hence it may be cheaper to still use WiFi opposed to leaving LTE burning. In Europe, you're already used to that tho.
These systems work on the premise of noise generators that blot out the external signals and a new carrier is presented just above the noise level that commands mobile phones to idle their transmitters down. In fact, one might say this causes *less* interference as you don't have a bunch of phones blasting away RF energy inside the cabin.
The real question is what will be the cost model for UMTS/LTE vs In-Cabin WiFi as each has a entirely different set of data protocols and are routed differently once they reach the ground network.
