Below is my "luxury" Field Day setup (operated from batteries in 1984 Itaska Motorhome). I can operate from 80M to 6M using a ladder line fed 80M dipole using a number of different modes including SSB, CW, RTTY, PSK31). I also have a QRP setup for 40M (with solar power).

For 2003,  some of us from the Honeywell Amateur Radio Association (HARA) operated as WM7A from Pivot Rock on the Mogollon Rim at 7100 feet altitude.
