[CQ-Contest] Bandpass filter

I should have properly stated that the addition of a 23' open stub on the
20m line brought the measured back fed power down to less than 1 watt. I
was writing on the Droid at my work parking lot and not putting enough
thought into my previous test setup. No 15m stub used in that test setup.

I am considering the addition of 4O3A's series L high power band pass
filters for placement after my Sixpack. The line of thinking is that there
is no worry about where my stubs are placed and I can look to resell my two
sets of W3NQNs to help offset the investment. I know the cost is high, but
I believe this will help with the presence of such strong fundamental
signals with my driven elements so close on the C31XR and the 40/80/160
antennas located within 12'.

Thanks for the continued information Tom.
