[hpsdr] Munin III

Fri Nov 12 00:18:16 PST 2021

Hi Dick.

Thank you for this information!

As the very old CAD program(Ultiboard v5.71) I used until this year was 
meant for manual handling by the PCB manufacturer, the extension of the 
file did not give the right information for the layer if used in an 
automatic process. But if the manufacturer just open the Gerber files in 
a Gerber viewer, he can read the necessary info written on the file.

Now I have changed to Kicad and I understand that some manufacturers 
have had some problem also with Kicad files but they seems to be solved 
now.

I have updated the github with BOM for the Munin III board and I am 
working on a description how to make the output PA Transformer.

73, Kjell
