"The main thing I am thinking is how to display the entries so that people can gain instant knowledge and use that earlier entry to improve their entry."
Motivation is the key in any competition, options:
- for the common good,
- for the price,
- for fun.
Mental stimulation ovelaps, but nobody will reveal what s/he thinks is the best if there's a 200 dollar price involved. Also, to test antennas you'll need equipment, so sending a second receiver is moot as a price.
Outernet and satellite signal reception is interesting for people, I see from my webpage stats, more than 10,000 have read the easy outernet antenna post, so it's clearly a current and exciting aspect of radio.
Some of the categories listed above are only interesting to a limited set of people, complicating th=e competition.
As for the learn from mistakes, I think that the competition could be run in two stages, with only ONE category, entrants got 168 hours and ten dollars to build the best antenna. Other categoies for mobile ops etc will not bring in sufficient entries, no general appeal.
So ONE category, 10 dollars, 168 hours, get the best signal to noise ratio with an Outernet kit. Best Five gets loads of money.
Next stage, build and experiment with designs above, make them better.
Before it comes up I'll not enter the competition, Outernet is already supporting me (Syed if you're reading this it would be good to be able to reach the office, or talk to the company in a different channel, please. PM..),, I've tested different antennas and will make them public for free, my joy is getting Outernet reaching a wider audience.
Please let me know what might be required in the future on my part.
