Several years ago, I bought W6OSP's LP100A from his estate. It came with 
one sensor, and I bought a second, sending the first back to Larry to 
calibrate for me. I have one sensor on the output of both power amps, 
and the LP100A autoswitches to display the one that is transmitting.

I'm VERY happy with it. I'm currently using a borrowed KPA1500, and find 
that the amp and the LP100A are within a 1-2 percent of each other.
