  In short, I agree with you.  When the W4MCO-10 digi is reborn, it'll 
allow FL7-7 and up to WIDE3-3.  For the brief time it did live this 
weekend we saw the usual crowd from Melbourne & Titusville but also new 
stations from the Tampa area. 

  Now, putting together a non-144.390 MHz backbone through the state for 
FLN-n communications is an interesting proposition should Talahassee 
ever become interested in what us folks down-under have to say...  But 
that's another topic I guess.
