Years ago, when i was young, i've done an experiment with a portable MF 
equipment which completely fits into a backpack, including battery, PA, 
antenna (TX antenna!) and measuring equipment as well as a netbook.
I had CW QSOs with a horizontal dipole just 4m above ground in the 
forest using 50W from a small by powered by a 7 Ah accu. These QSOs were 
with DF6NM and DL4YHF. And it was July in the late afternoon!

PS: Ignore the theory, just do it!
