Anyone know why and if it is normal for the swr to go up when amp is on and in use? I have an ameritron al-811 and the swr on the radio is 1.2 to 1 when talking on radio alone, when I switch on the amp and talk the swr swings up to 2.0-3.0 to 1.

I dont know if the radio is just seeing this from the amp being turned on or what. I know my swr of the antenna is 1.2 on my mfj 259 and radio shows same till like I said the amp on changes it.

Help.
