I see something similar with my (non-Elecraft) amp. The amp's display
matches a Bird 43 I had connected with a 12 inch cable from the amp and
then goes into an accurate 50 Ohm dummy load. I usually do not leave
the Bird in-line, but had this set up for testing the amp when I first
got it.
The remote LP100 sensor I have is actually on a cable that is about 3
feet from the amp and it usually reads HIGHER than the amp does, even
into the same dummy load.

Subject: [Elecraft] KPA-1500 power reading ?
The KPA1500 is new to me and very happy with my purchase . I'm using the
LP-100A watt meter and comparing it with the KPA-1500 they both read close
enough 10 to 160 . On 6m I'm seeing a bigger spread with the LP-100A reading
1500w the KPA-1500 is showing 1375w . If you look at this in DB , it's nothing.
I know the LP-100A is very accurate and the only way to know for sure is to
have Larry at Telepost test it. Most likely wont do wont do that. Are their
others that see a difference on 6m ?
Thanks Ed N5DG
