Is external power required for the CN-801 meters to operate, or is it only required for the lighted display?

A few years ago, I converted my trusty Drake W4 wattmeter to true peak reading using the info on these two sites:



Simple circuit to build. Works great. Powered by 12vdc/1amp wallwart.

To expand its usefulness Drake provides a chart for using forward and reflected power to calculate SWR.

The peak reading conversion turned this quality instrument into a meter as good or better than anything out there. Fun project too.
