Feb 08, 2011 · I have built 2 WBR’s now, both with good results. The second one was a bit deaf, but there is a mod for that, which solved the sensitivity issue, but resulted in breakthrough from a strong local AM broadcaster. A simple BC band trap solved that and now I have a delightful regen for the 31M SWBC band (my other one tunes the 40M amateur band).. "/>
