If you have an MFJ-259 antenna analyser is the analog SWR meter reading the same as the digital one?
Mine has always been a bit cock-eyed. The digital display is blob on but the analog meter is about .2 too high. i.e. a 50Ohm load shows 1.0 on the digital display and 1.2 on the analog one. 100Ohm shows 2.0 on the display and 2.2 on the analog one. It seems to have a constant offset with frequency.
Now it’s been like that since I got it 5+ years ago. I always the use the analog meter to show trends as that’s nigh on impossible on the digital display. So it’s a case of twiddle stuff and watch analog meter till it’s at minimum and then read actual value on the LCD. However, I’ve been using it a lot this weekend whilst playing with some ideas for antennas for 20m-10m and the offset is now bugging me. I’ve found calibration details on various websites but before I get the calibration hammer out I thought I’d ask to see if mine is squiffy or if this offset is typical.
