I'm intrigued by near-QRP power level operation.   I may bring the rig and 
buddipole to field day and try it out.  Of course I've never done a field 
day and have no idea how to operate in one.   From what I am hearing now on 
HF  I  can't imagine HF band conditions being so good that 5 watts can 
actually enable one to make long-range SSB phone contacts.   I'm looking 
forward to it.
