 If some of the AM users on 3885 went FM right now the howling would start so
fast about it from the weenies on either side of them it wouldn't last long 
enough to get any idea it it would be feasable.
 Why someone elects to `park' 5KHz away from a recognized AM area and they 
bitch about the problem is beyond me.

 JE> Can try...CW starting Saturday night (if I'm here - schedule is so 
screwed
 JE> up now, I don't know where I'll be) at 2000 CST (0200Z ?) at 3700 to 
3705,

 How about -this- Saturday from 8pm eastern around the freqs in netmail?
 If we can get this to work maybe we can get an informal net of some sort 
going
for anyone in the HAM related echos to join in on this winter for some voice
fun so we can place a voice with what we see on the screen.
