Comments:

The K3/100 was a Christmas present from my XYL. Although it arrived three days 
after Christmas, I was excited to get it built and on the air. By the time the 
contest started, I hadn't read the operating manual yet. Just enough to work 
the contest. 

I must say that this little rig impressed me. I only have the stock 2.7 kHz 
roofing filter, but I was able to dial down to 300 Hz with no problem. There 
were only a couple of situations where nearby signals caused pumping of the AGC 
-- a narrower roofing filter is definitely under consideration. 

My K2/100 would definitely feel extremely warm after calling CQ for 10 minutes. 
The K3/100 didn't break a sweat. It was relatively cool and silent the entire 
time. 

The inverted L was erected just before the ARRL 160m. I added four more 125 
foot radials the day before the contest. I also trimmed 9 feet from the element 
to bring the resonance up from 1740 kHz to something in-band. This must have 
improved the radiation efficiency quite a bit. The received noise went up 
considerably after these changes -- this antenna sounds much more like the 
shunt-fed tower I have in Gwinnett County.

As in the ARRL 160m, the antenna worked well. With a few exceptions,  I could 
work most everyone I heard.

I started a little early. I didn't expect to work anything until the sun went 
down at around 2230z, Imagine my surprise when tuning around with the K3 around 
2030z and finding stations on the air. Another 20 minutes, and I had the 
computer set up to log and worked a handful of stations. Then I found a nice 
spot and started calling CQ.

This contest was mostly a CQ-fest for me. Rate was pretty slow at first. I was 
reading e-mail on my second laptop between Qs. After sun-down, things picked up 
considerably. This was an absolute blast. There were a couple of times the rate 
really kicked in for a brief period. I found out later that these coincided 
with a couple of spots I got. 

Not a lot of DX in this contest. NP2, and VE were about it. I did hear a couple 
of europeans, as well as CE, but the couldn't hear me. (Well, it sounded like 
they couldn't hear anyone)

This would have been more fun with a little more activity. I've never 
understood why the Stew Perry isn't as active as the ARRL 160m. 

Looking forward to the CQ 160m contests.
