Thanks Shoman94, this is a lot of useful information. I appreciate the time and effort in your response. I have found so many postings on this forum that were really useful.
One clarification, when I referred to the Long Island stations, specifically I was thinking of WLIW 21 which is at 206 degrees(magnetic) which I am seeing as a delta of 39 degrees from the NYC stations at 245 degrees. Is the thinking that I would aim at 245 or would I cheat toward 240 or 235? I am not asking for an absolute, understanding every installation is different, just looking for the approach and logic. This was the basis of my question about the Db4e.
Lastly, is the below FM trap recommended? Does this get installed before the pre-amp (e.g. Juice) or after?
