I bought the squares as they are smaller than the ones I made and while harder in someways they kept the mess down. I bought some J310&#8217;s from Mouser and either the ones I had were less than optimal or I fixed something in the resolder. I ended up with 4 batches of those. They all tested different and the Mouser sourced ones had the lowest Vg (turn on voltage?) according to my 12$ tester at 1.65 V rather than 2.35 or 2.65 for the Amazon ones. The noise on it sounds almost identical to the noise on my Kenwood on the same antenna. Thanks Everyone. It&#8217;s part of a very long term goal.<\/span><\/b><\/i><\/span><\/div>\n<div><span style=\"background-color: white;\"><i><b><span face=\"gg sans, Noto Sans, Helvetica Neue, Helvetica, Arial, sans-serif\"><span style=\"white-space-collapse: break-spaces;\"><br \/><\/span><\/span><\/b><\/i><\/span><\/div>\n<div><span style=\"background-color: white;\"><\/p>\n<div class=\"separator\" style=\"clear: both;
