[hpsdr] Munin III

[Kjell Karlsen]

Hi Tony.

It should not be difficult to identify each file as it is written on the 
file in lower left hand side. The CAD program I used is very old but 
still follows the present rules. If you use a Gerber viewer you can see 
this text.

There is nothing I can do to improve this.

One manufacturer that still can use the files is boktech.cc, they have 
no problems.

I have now started to use Kicad so future layouts from me should not 
have similar problems!

73, Kjell
