HI David....how are you going to educate the EU stations who use Digital 
modes in that area
especially as the sunpots start to rise and prop gets a lot better
i noticed what i think is Packet/APRS signal on 7035.5 (approx).....this 
signal would get swamped by a VK who doesnt know what APRS sigs look 
like if he/she was chasing DX on say PSK....also not all VK/ZL stations 
have a copy of any bandplan not being a member of WIA/NZART
im not saying go away....im just trying to point out what is a problem 
with that area of the band
WSJT JT65A /WSPR is operated around 7039 in both EU and USA

if you beacon say every 15min and a VK/ZL starts PSK on 7035.5 after the 
beacon he may not have seen it or starts working the DX and then your 
beacon comes on you interfere with his QSO
a very difficult situation for both stations.....

im only trying to point out the difficulties of operating beacons around 
7035
you have as much right to the freq as any other station but as with PSK 
contacts cant complain if you get stood on
