WOW!  Congratulations on your great breakthrough!  I am very curious to 
learn if you have any equipment for 6m, or can suggest any station over 
there to contact about a 6m JT65A mode sked on their moonrise.  I have 
heard that the power restrictions are only 50w on 6m, but perhaps a 
special permit can be obtained to run a few hundred watts output for EME 
tests...this is the best time of the solar cycle to work 6m EME, and it 
sure would be wonderful to get a station operational from China to take 
advantage of it!

I have now completed with 68 different DXCC using 6m EME, and most of 
those contacts were with single yagi stations using JT65A mode when the 
moon was near the horizon for them.  The extra ground gain they get when 
their yagi is aimed on the horizon is what makes such a contact 
possible.  For very high gain yagi antennas that are being constructed 
by the users and proving themselves in numerous successful EME contacts, 
I suggest: http://www.yu7ef.com/

Even if you can only run low power, I would be happy to arrange a sked 
during your moonrise, so you can test out your antenna and confirm where 
the ground gain lobes are for your particular installation.  PSE keep us 
informed, and good luck in your project!  MNI TNX and VY 73, Lance
