unIDed CW beacon on ~2804.31
 

On Sat Mar 5 07:00:48 UTC 2005, I heard weakly a repeating CW beacon on
~2804.31Khz in Denver, Co. USA

......... ..-.

The last char is definitely an "F" but I either am hearing two chars run
together or 7 dits preceding it. My Google turned up nothing. Any one
else hear it or know what beacon it i?
