The noise floor at the WB0WNX-5 site,located at the KUSD analog and digital 
TV and FM radio station, in Beresford South Dakota has risen drastically 
since I first installed the node a few years back.

Since there are so many node on 144.390 I figure I am not the first person 
with this problem.

I was was wondering if anyone has a pre-tuned band pass/band reject cavity 
that will allow for 50 watts of power for sale or know who sells one?

Or is there a better way?
