Comments:

My first sprint using high power. Managed to attain a new personal  
best, although the event wasn't without a few surprises.

Bands seemed to be mediocre. 20m was open pretty long at the start,  
but I still managed a few close-in mults. Thought I'd drop out early  
and go to 40m, but things picked up at the end of the first hour, so  
I hung in until the rate dropped. This pattern also repeated itself  
on 40m.

First surprise came about 20 minutes into the contest. Every time I  
transmit, I would faintly hear a rumble from upstairs. Discovered  
that my 600 watts on 20m was causing the garage door opener to go up  
and down. I wonder what the neighbors thought of that. So, the amp  
goes off for the rest of my stay on 20m.

Things went better on 40m, and the amp played nicely, even into the  
slight mis-match of the sloper (about 1.7:1 VSWR). Rate was good on  
40m. Had my best rate in the 3rd hour, with a big 44 Qs.

Went to 80m in the last hour. Amplifier was more difficult to tune,  
even though I had a good match through the tuner. Could only get  
about 300 watts hour without running excessive grid current. After a  
few minutes, I noticed a "spitting" sound from the amp intermittantly  
when keyed. May have been some arcing, hard to tell if it was in the  
amp, or in the tuner. In any case, I turned the amp off for 80m.

Had to remove one QSO from a contester who jumped the gun after  
answering my CQ -- I come back and ask for a fill, and he's gone on  
to the next caller. Guys, you gotta wait until the QSO is complete.  
Your reward is a Not-In-Log.

Every QSO in the sprint is hard-won. By the forth hour, some of the  
CW just seemed like a blur. I wonder what the sprint would sound like  
if we had a speed limit of 20 wpm. I'm sure some might fall asleep,  
although there certainly would be time to hit that second radio.

Still need more practice in this one, and some time to work out the  
station issues with high-power. Good news is that I recieved a  
Cushcraft A743 kit, so I'll soon have a better antenna for 40m.
