Hi all, This thread is getting rather long but I want to put my 2 cents worth in. The huge discrepancy between the K3 indicated SWR and the LP-100 shown in Stewarts original post is *not* normal or expected. Either there is something wrong with the data or the K3. I am finding that the K3 readings tend to be a little on the "kind" side. I don't have a precision meter like the LP-100 but have come to find my MFJ tuner with its cross-needle analog meter reasonably trustworthy. My K3 readings are generally lower by 0.2 to 0.3, but no more. This is both at the 10W level and the 100W level, and both at nearly perfect match and SWR more in 2:1-3:1 range.
