[RTTY] E-mail Address for N2OW?

[Arsk0jn at aol.com]

Does anyone know the e-mail address for Dimitri, N2OW? "ra9usa at hotmial.com" 
is no longer valid. I would like to ask him about the possibility of operating 
RTTY from 4U1UN in the near future. I believe it has been more than 4 years 
since a RTTY operation has taken place from UN Headquarters although a number of 
other operations have occurred and it is becoming very rare to many hams 
throughout the world..
Many thanks,
Joe, K0JN
