[Elecraft] KPA-1500 power reading ?

[Ed Stallman]

Lou , just checked again on the HF bands

80m LPA=1495 and KPA=1501

40m LPA=1476 and KPA=1421

6m LPA=1512 and KPA=1325

This is not concerning to me at all . My curiosity and a cold rainy told 
me to see how others compared . I suspect this is the case with any two 
watt meters . I know it's adjustable in the KPA 1500 but I'll not bother 
. Thanks everyone for ur reply .
