The LP100A claims typical 3% absolute w/ NIST calibration (and Larry does that for you for free when you're done building the kit). I really dig that you get to build the kit including the coupler. I also like that you can use it as a field strength meter. Not to mention that in field strength meter mode it goes to MUCH higher than just HF frequencies. I've used it to take antenna patterns for YAGI's at VHF frequencies. It also can give you a lot of the similar information that people buy the MFJ analyzers for too. I also like being able to get the information in several formats. You can get FWD power and REV power, or you can get FWD power and SWR, or FWD power and return loss in dB (my personal favorite).
Anyway I'm pretty pleased with mine and find it to be VERY accurate and I compared it to an actual Agilent lab watt meter from work. ~BTH On Wed, Oct 21, 2009 at 7:58 PM, Grant Youngman <n...@tx.rr.com> wrote: > The LP-100A (I have one) is spec'd at "5% or better", without saying what > "or better" means, and < 2% relative, which isn't a spec Elecraft provides > for the W2, but which one could reasonably assume is in the same range. > > I don't see any practical difference.
