I got the Network PCB in the mail today - Thanks much. I cannot seem to find the cutting template for the enclosure that you refer to in the Network Manual. Do I download it from somewhere?
Thanks again & 73,

- Oops, sorry Sebastian. I forget that it was a separate document from the instruction sheets. I ve attached it to this email. 73, Jim W8ZR _____ From:Message 2 of 4 , Jul 9, 2012View Source
