I am an activator living in central Texas and the summits in southeast Oklahoma and west central Arkansas offer a wealth of opportunities for me. Here is my target list of summits in the Poteau, Oklahoma area: W5O/OU-002, 005, 006, 013, 014, 017 and 018, W5O/SO-002 and W5A/OH-001.
These are already-activated 4-to-10 point summits on public lands (Ouachita National Forest) selected because they are “drive-ups” or involve hikes of only a few miles with elevation gains less than 1000 ft. I am working through these now, but I think there are many more good opportunities in the Ouachita range in central Arkansas and closer to you in the Ozark range in northern Oklahoma and Arkansas. I suggest searching through the summit lists covering those regions for guidance from the comments posted by previous activators.
My rig is a 5-Watt HB1B and I feed it through a small MFJ tuner and 450-ohm window line to a 40 meter inverted vee, with an apex at the top of a 20-foot telescoping fiberglass mast. The setup works well on 40, 30, 20, 17 and 15 meters. I first tested it in my backyard by calling stronger stations that I heard.
