Maybe this is a dumb question, I have a rm 503 hd amp inline before the antenna, and with amp off i get a flat match. When i turn the amp on it goes to 2.5 without recalibrating, But when i recalibrate with the amp on it's 1:3.What i'm asking is do you recalibrate with the amp on and if so is my swr reading a proper reading with amp on
thank you

Re: SWR Reading
Make sure you change the watt reading on your meter. You could be getting the sad readings when your meter is still on 10 Watts. I don't know for sure, but I love the RM KL 503. Gotta be sure everything is set right when you transmit. On AM, pre amp off, correct wattage, lol, all the things I mess up all the time.

Re: SWR Reading
Yes, you have to recalibrate because of the additional wattage.

This is why I like a cross needle SWR meter over a traditional meter.
With a cross needle meter I instantly see if both values (output power and reflect) are within range of what I expect. And that in all power settings without recalibrating.
