[hpsdr] Pandora Layout Help

[Kjell Karlsen]

Hi Richard and Jeff.

I have built 2 complete HPSDR transceivers. The first is with a PC and  
monitor in the same box. This one has shielded boxes around all units. The  
2.nd is in a smaler box where only the assembly with Atlas, Ozy, Penny and  
Mercury are shielded. Both units can run 150W PEP and I have had NO  
problems with RF feedback. I have also operated both stations without the  
top and bottom shield and there has been no problems. I have even tried  
with everything spread on my work bench without problems. Just try all  
inside Pandora and see what happens. I do not think there has to be a fan  
to cool Pennywhistle if the PA transistors are bolted to an outside wall  
on Pandora.

Good luck, 73 and a Happy New Year!

LA2NI, Kjell
