Beth and I just returned from a 5100 mile road trip. My KX3 went along. Even with hot weather and family obligations I managed a few picnic table QRP QSOs.
One of our first stops was Pratt, KS. With 4 hours of free time I asked around for the local park. Lemon Park has lots of trees, shade and tables...prefect for my afternoon. I had nice QSOs with K5KW on 40 and W7LXN on 30
Another stop was Pullman, WA. Here I had an afternoon in Sunnyside Park. I set up next to a walking trail and the frizbee golf course so I had a couple of eyeball QSOs in addition to the ham radio ones. From here I worked KC4ZPB, W9CC and VE3XY, all on 20 CW.
My KX3 running 5 watts CW feeding a 20 mtr endfed zepp continues to be a fun traveling companion.
