I'm just guessing as I have seen the same thing on my Magnum. The SWR will change with power output setting up/down. The difference between these two radios, is that the Magnum uses MOSFETS and the Galaxy uses bipolar transistors for output. I was told that the MOSFETS are a bit more sensitive to SWR changes. If that is true or not - I can't really say for sure.
