[Elecraft] KPA-1500 power reading ?

[Ron Manfredi]

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.

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 ?
