Hi Marshall,

Yeah, I would love to have an amp.  But, it's just not in the budget. 
 Actually, homebrewing amps is one of those "sub-hobbies" I would like to 
pursue someday when I have more time to play.

I have small bricks for 2 and 432, but, we managed to get the power cords 
crossed at field day and killed them both :(   They are on the "to be repaired" 
shelf.  I hope to get time to dig into them eventually.

Currently, I am slowly rebuilding the home station after a couple of years of 
inactivity.  When I get the home station in reasonable shape, I hope to get 
back into Roving.

73
Dan

      I think that many rovers and some fixed stations just don't
      appreciate what having some power will do for your logs.  KW amps
      are easy these days, so there is not much reason to be running
      around with 100W or 50W.

      time) and ran it off 4 large 13.6V batteries in series.  We got
      700W output--hour after hour.  IF you worked up a circuit to
      charge those batteries when you were not transmitting, you could
      run 700-900W fairly easily.

hope to hear everyone on in the CQ-VHF this weekend!
