Anybody know what the diodes are in the MN2700 wattmeter ?  I suspect they
are the same in the WH7. They call em AA119 in the MN2700. I see the same
diodes in the TR7 wattmeter.  I kinda suspect they are germaniums like a
1N270 based on how well the SWR reading  still works at low power. I am
asking before I unsolder one to see what the forward is on them. Maybe
someone knows what they used- and where to get replacements .
