My Usual setup for Parks on the Air(POTA) is a Yaesu FT-897D, Alpha Antenna MagLoop, Jackery E300, SignaLink USB, Lenovo T440P, Apache 4800.
My experience with this setup has led me to over ten thousand contacts in just one year. With the Alpha Antenna Magloop I have found that the antenna on FT8 can be operated at 50 watts on some bands however, sometimes the ALC can start to respond on some of the lower bands. However, with the larger loop and with 80 meters I have found that there is a hard limit of 10-20 watts. I have created several videos showing how I setup my POTA station.
