If I copy th PDF directly using the USB wire it works fine. How do I turn off the compression when sending with Calibre?
How are you doing this? To my knowledge, CC does not run on any Kobo device. If you are using koreader then you need to ask there.

And in any event, CC doesn't touch the contents of book files.

EDIT: I reread your post and you are using koreader. As I said above, you need to ask there if it does anything with the transferred files. You could also ask in the calibre forum about the effects of metadata updates in files transferred to devices. The "wireless device" has no control over that.

EDIT 2: you say if you transfer by cable then the problem does not occur. Are you using calibre to do that transfer, or are you copying the file by hand? If you are copying by hand then you are avoiding calibre's automatic metadata update.
