Sounds like a Canadian NDB (non-directional beacon).

What I'm hearing is some strange signal which seems to have a
surpressed carrier on 500.0 and sidebands both above and below at about
6 khz intervals...ie +/-6, 12, 18, getting radidly weaker as they get
further from 500 khz. They are modulated A-2, MCW, with what seems to
be code with three characters...a dit, a short dah, and a long dah send
in the format {long dah, two dits, variable number of short dahs (n= 3
to ~20), long dah, pause} with timing like a busy signal on a landline
phone.

Are you really in the Finger Lakes area, or somewhere else?

?? anyone have any idea what this might be ??

I'll fire up the FRG-100 and maybe some other gear, and take a listen
from central .ok.us; not sure what if anything will be audible here.
