? You might want to drop down a wire size to #30? I had trouble getting the ones done with 32 turns let alone 38! #30 I was able to get 38 turns. Frim memory wire size is not that critical just number of turns. I will send SA plot of 30M later to see if it made a difference. These filters are fairly wide (I plotted 80 and 20m so far) to start with so I doubt there is much difference.? Tim W4YN? |
