Wow that's amazing Dennis!!!! 

The one thing I really like about this contest is the DX station sends
their power level. I worked a horde of 5 watt stations, mostly all JA's.
In the past when I would work single band 80 and I would work one 5 watt
DL station it was almost like an alarm was sounded within the Bavarian
QRP club over there and they all line up for a Q. Unfortunately, several
of them were a real strain to copy. This weekend I had to shake my head
several times when I would work a very copyable 5 watt station then I
would struggle with the next station that would send "KW"!!!! Says a lot
about a good antenna!!! 

Anyway your run this weekend is quite impressive!

I grabbed a 9V battery off the desk that had been used for something else but measured a bit over 9 volts.  I operated about 2 hours.  Power at the beginning was 1.2 watts and by the end, voltage was 7.7 and power output was 700 milliwatts.  I stayed mainly on 20 meters and found that many DX stations answered me on the first call. Some required several calls and a very few couldn't copy me at all.  I was surprised that it worked so well since I was down an average of 30 db from a kw station.

It's not like operating a "big rig" but it is just a little bigger than a pack of cards.  I'll be taking it out to the park when the weather gets a little better.
