[Swan] WM3000 meter calibration

[David Shipley]

Does anyone know a method for calibrating this SWR/Power meter. I'm sure 
mine is out of calibration!
Also when I transmit with my 700CX or with my Yaesu 890 it turns off my 
Hitachi HDTV. It also turns on a touch lamp. I'm using a Gap Titan antenna 
mounted on the roof of a 2 1/2 story house. I'd like to know if anyone has 
seen this problem and what I could do about it!
Thanks
