I would like to know the following as it pertains to digital modes such as FT8. It is recommended that you keep your power output low, for example 5 watts. If all of the other variables relating to the setup of your digital station are optimum, such as sound card input and output volume, is there an advantage to using a gain antenna to increase your signal strength? In other words, are you better off increasing your signal strength by increased antenna gain or can you accomplish the same increase in signal strength by increasing your power output? Is there a greater danger of creating QRM by increasing your power output? The reason I am asking is that I want to operate portable and choice of antenna is important. Thanks so much for your comments.
