Re: ATU 10 by-pass


 

Hello, David;

Everyone's responses are greatly appreciated. However, Unfortunately, I am finding them conflicting and hence confusing. Let me make sure I have this correct.

Talking about the ATU10 (NOT the ATU100): If I hit reset, and then immediately turn the unit off, It will essentially be in a by-pass mode? Input shorted to output? Is that correct?

If this is so, then the ATU10 DOES have a by-pass mode. This would explain why, when I have the equipment set up in the order of: xcvr then ATU10 then MFJ then ant configuration, and I turn off the ATU10, I still get normal power and swr readings on the MFJ, yes?

With ATU10 on and working, after hitting reset and putting it in tune mode, at for example 7.150Mhz,, AUT10 gives me 1.5 swr @ 1.4w, while the MFJ is reading 4.0-4.5 swr @ 2.5w. I am not sure how to reconcile these diverse readings?

Then, following your though if I am clear, after I reset/off the ATU10, the MFJ gives swr 4.0 @ 3w.; a small difference. Is this significant?

Thoughts?
