Hi All

At the moment, I am using a 200 watt HF W2 Sensor on VHF, and while I
realize it isn't far from perfect, it is perfectly good enough to tell me
if I have LOTS of watts out on a remote VHF station or no watts out.

I could calibrate it against a known good watt meter if need as that is
easy enough to do.

Or, could I convert it to a VHF 200 watt sensor as it looks like Elecraft
is not stocking them anymore based on trying to order a couple from the web
page.

The W2 is a great meter for remote operation and we actually use NodeRed on
a RPI to make it web readable.
