[Elecraft] Looking to add LP700 to KPA1500 - ideas?

The Telepost LP100 (and I expect the LP700) are calibrated to NIST 
traceable standards.  I bought an LP100 kit (no longer in kit form) and 
did my own calibration after construction - then sent it to Larry for 
his real calibration.
Although Larry will not commit to it, I suspect the accuracy to be in 
the vicinity of 2% or better.

There are a number of LP100s in the Elecraft working area.  I don't know 
how often they are sent back to Larry for a calibration check.  What I 
do know is that they are better than the average Bird used by hams.
