I am using a MFJ-259B to tune up my Tuned Input circuits. I know to go for 1:1 SWR or as close as I can get it and 50 ohms of resistance(Rs). How about Xs? What value am I shooting for? 73, Bill ===== Bill Smith KO4NR __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com
