thanks for the reply.

i understand the theory behind it. i just dont get how to use it; practically?

could you give me an example, comparing an in game reading and how you would use that to determine what it is; according to the pdf.

thats what i dont understand. especially the column with the frequency scales on the right side of the document, i see they match the frequency dial in narrowband...
