Mini 600 Antenna Analyzer problem
 

Hope i can post this here,

I have a Mini 600 i picked up at a local hamfest. Was told working ok.

Problem i am having is the display is not stable. When doing any of the modes, the display is not reading right. It is all over on the screen. I have see on the web that should have a flat line type in the display. mine just jump all over the place and really do not know what it should be. I have added a link with some pictures that might help what i am seeing.

I have seen that there are some updates for other units, but do not know if it will work with mine.

Any help please, Mike - KB8SSH
