Ok, I will make it short.
As a result of the Campus Party 2012 in Berlin I just donated 66UD$ for the development of LMR4.
Why and how?
At the Campus Party in Berlin I brought the kit of ALF to sell it at the CP 2012. The kit contained all the parts to build ALF inluding the bottle caps. During the Campus Party I was able to sell 53 kits. As a thank you to LMR and it's members, the friendly community and the great help I got all the time I decided to donate 1 Euro (1.25 US$) for each kit I am able to sell for the development of the LMR Version 4.
ALF and my other projects would not exist without LMR where I got the re-start of my electronic activities.
