They do if you set them up right. For my V1, I have it set to limit the swing to 35W while maintaining a 1 to 2W carrier. But, they are able to swing full output if you want. The V2 even more so.I have one on the way - so was asking in advance of it arriving. V1s certainly didn't act like you're describing. Good to know. I am aware of the menu based adjustments on the v2. Thanks
