June VHF contest, 6 meter DX window

[TSkelton@engineer.clemsonsc.NCR.COM (Skelton, Tom)]

I have been off 6 meters for about 5 years, but with the new
Kenwood TS690s and 5 element yagi at 85 feet I will be back
for the June VHF contest.  Hope to work a bunch of you VHF
types there.

Now for some advice needed:  years ago, we stayed off
50.110 MHz as the DX window.  Has this changed any?
Due to all the great (former) propagation and new countries
allowing 6  meter operation, has the 6 meter DX window
changed?  Thanks in advance for any info.
