Notes on Autek Wattmeters
WM (3) intermittent. W0CG
brought to to Idaho 5 April 2017, shipped to N7IR. From N7IR: The
fault was a broken 1/8 Watt resistor lead, caused by corrosion. I've replaced
all of the resistors in this unit with new 1/4 Watt carbon composition or metal
film resistors as required. It's been recalibrated to agree with my Bird 43 and
100 Watt Bird slug on my Bird 150 Watt dummy load.
Only the top of the board showed any signs of corrosion, so it's probably caused
by deposition of saltwater aerosol. I will seal up the large hole in the back
of the meter unit with duct tape. That should keep the rate of new corrosion to
a minimum.
N7IR will ship to WI9WI for his May WPX CW trip. WI9WI
brought it back and left it at the station on the Station 2 - 3 desk corner.
