John :

I use VOACAP to predict propagation. I have found that it is fairly 
accurate. Also it is simple to use. You don't have to enter any 
parameters such as sunspot numbers because predicted values for these 
parameters are already built in. All you have to do is enter your 
location and the DX location and indicate a parameter regarding your 
station's power level and type of antenna system.

You will find that propagation is not the greatest from Oklahoma to VU4. 
However, there are some halfway decent openings short path and also long 
path.

The best short path openings: 0000UTC to 0200UTC on 15m and 17m
                                             1500UTC to 1700UTC on 15m 
and 17m

The best long path openings:  1300UTC to 1800UTC on 10m
                                             0000UTC to 0100UTC on 15m

Out of all of these openings the very best is around 0000UTC to 0100UTC 
short path on 15m

For complete info go to www.voacap.com/prediction.html

I think if you have a gain antenna (such as a tribander or log periodic) 
that includes 15m coverage you will be able to work him -- especially on 
CW if you are running with some type of linear.
