INLINE SWR METER(S) VS RADIO SWR METER(S)

Hello All,
Maybe someone can clear this up for me? With my radio(s) ON and amp OFF my SWR reads about 1.0 - 1.1 across 40 channels per the built in SWR meter on the radio(s) and the inline SWR meter. Just FYI, I purchased 3 brand new (different types) of inline SWR meters just to be sure. With the radio(s) and amp ON, the inline SWR meter reads about 1.18 to 1.24, which i believe is normal due to the harmonics from the amp. BUT BUT BUT, the SWR meter on the radio(s) read 1.6 - 1.8? Should I care? Should I ignore the built-in meters because the inline meters show a good SWR? This morning I talked to Montego Bay Jamica (From Rhode Island) with no trouble at all. That being said, I'm thinking that I do not have an SWR issue?

Thanks
 

The input and passthrough tune will be different so that's probably why you are seeing different readings. Like undertaker said, anything under 2.0-1 is fine. If you are driving your amps within an inch of their life you'll want to have lower SWR, otherwise up to 2.0-1 doesn't affect your signal or hurt the life of your equipment.

Thank You Gentlemen. I failed to mention that have tried (2) different Amps. Carl Built 400DH & Thunderbolt 305. I think the Thunderbolt 305 is a "Cleaner" Amp regarding Harmonics etc. Maybe I'm crazy?

Thanks
