I Suggested a  timed  beacon system, a long time ago   , similar to the 
g3plx  5 meg  monitoring  system , where  stations simply took an  available 
time slot and transmitted a  long  pulse ... monitoring  software  then 
simply  looked in the  slots and gave a  real  time s/n  reading , also 
enabled  stations  could  be  in rx  mode during there  'off' period ....

Then  wspr  appeared .......game over ..or is it  ...

So what about a  timed  beacon system that  uses  allocated time slots and 
the  monitoring system  keeps track  or who is using  which slot  ..
what a  strange idea .. but  for  LF  may have  big advantages

All  on the same  frequency -so  no  problem  with  Ae Q / B/W leaving  the 
band open  for other modes
NO   need  for  silly  long  tx periods , melting  station accessories
ONLY   needs rudimental  time  lock

OH and one  little  oversight .. all  you  need  is a  -CW-  transmitter , 
no  frequency shift keying , no  audio  to  rf  translation ,

Down side . needs  some one to  write the  control  software ........in fact 
Andy , ran the  basic idea  on 500  for quite a  while , using  -one-  of 
the  three  time slots  of the  g3plx system, with Gary providing a  off-air 
on line  monitor  200  miles  north
