[Boatanchors] [HallicraftersRadios] Bird Model 694 Termaline Wattmeter 1 KW

[Walt Cates]

I got the pdf file. Unfortunately, under calibration it says the RF unit is not a field maintenance unit.

My Thruline 43 with the 500wt and the 1000wt both indicate my SR-2000 in low power CW is producing 480 watts.  The 694 indicates 215 watts. The antenna analyzer indicates the 694 load is 47 ohms at 3MHz and 51 ohms at 28MHz, with a VSWR of 1 point zip. So,,,, it is ok to use since I rely on the 43 for measurements.

Walt,

Why don't you reach out to Bird in Solon, Ohio (suburb of Cleveland). Everytime I reach out to them they are always cooperative.
