Ah yes, there you are. Frequency check shows you to be 166665.53. You're plenty
strong at the moment even during the night/day transistion. Will take another
look after sun up. Is this the 50' square loop or something different?

Will have my RG-58/#12 number for you later. Is it a good brand of RG-58 or old
RS stuff with about a half dozen wires for the shield?

Will check my core stash when I get to work.
