Sorry for the repeat bandwidth folks, but I though that the title of the message before would not have garnered any readers.
 
 
Hello Folks,
 
I may be way off base here but I am going to ask this question anyway. 
 
I just looked at part 15 regs and sure I missed something.
 
Background:
 
A thought occured to me while looking at the the 3 stations capture NC LEK BRO  put up on the web.   Sorry I am at work and don't remember  who it was.  Seeing all 3 staions fit into the space of 1 Hz looked very interesting.
 
I got to wondering if a person had lets say 2 lowfer stations on his property on 2 different frequencies .25 HZ apart, both running 1 watt into seperate antennas that would  be legal right??????
 
Now work with me here :>)  What if that same operator were to have a 8 transmitters(or some other number) on 8 freq. seperated by .25 Hz  with 8 antennas would it still be legal?   Yes????
This would mean 8 stations in a 2 Hz bandwidth correct?
 
And what if  all the transmitters were run by a common keyer that could be programmed to send a given specified length of dot/carrier in every one of those 8 positions with a common stop and start time.  Would you not see a specified length of dashes in all 8 positions on RX?
 
And could these 8 positions then not represent a binary code, or an ascii code, or some other code?
 
And all the above is true then could not the operator of these 8 stations, and acres of of antennas send a complete ASCII character in 1 dot length? 
 
Sorry for the craziness.
 
Then what if one could combine those 8 seperate transmitters into 1 antenna system?
 
Does part 15 preclude this?   The power is all on different frequencies, none exceeding 1watt, no 1 frequency exceeding the legal radiated power.
 
An identifier like "NC" could be sent in 1 minute assume 30 second dot length?
 
There has got to be some legal reason why this would not.
 
Some help to put me out of my misery.
