For extreme qrp you should also try out the new mode ros With 5 w
and a wire you can work the world with almost no conditions (band closed)
I consistently work the world on 20m with only ONE watt (My PSK-20), an
attic wire dipole, DigiPan, and PSK31, whether the band is open or not,
but
As multi mode soft you can not beat multipsk (i think)
For extreme qrp you should also try out the new mode ros ..
With 5 w and a wire you can work the world with almost no conditions (band
closed)
For sstv I use mmsstv most of the time (or easypal for digisstv)
Just my 2 cents
