[hpsdr] HPSDR Question

[Dave Meitzen]

 I think I have a RF feedback issue.

Using my HP431C with a 40db 100 watt attenuator I can confirm over 100 watts
from my Penelope/Penny/EB63 string.

If I connect to my 80M antenna through a Bird with a 100 watt slug My PEP is
around 14 watts.

The antenna measured SWR is less than 1.3 so I would not expect this to be
an issue.

What is the best board stack starting at the LPU side? Right now I run
Mercury/Ozy/Penelope/Excalibar/Antenna switch.

Any words of wisdom will be greatly appreciated.

Best Regards
Dave aa9tt
