Thank you for your entries, please see the feedback below:
#43 We are worried that the radio tower is too detailed for embroidery on shirts etc. Perhaps try simplifying the graphic, and try incorporating it with the text in different ways.
#42, #41 and #40 are the most interesting of your submissions.
#39 This design looks too similar to the BMW M logo.
#38 This logo is too simple and doesn't give any indication of the brands values or identity.
#37 On its own this logo is not designed enough, but it is a great starting point. You might be able to use the swooshes in other ways. Perhaps lay them behind the font appearing above and below, or use different sizes to represent the edge of a globe above or below the font. Keep working with this design.
You may wish to increase the character spacing slightly on the font, it feels a tiny bit too compressed horizontally.
