Practice makes perfect
While contesting isn't everybody's cup of tea, it can be an excellent way to hone the skills you will need to operate in a high stress DX location. I had bursts of high QSO rates while on St. John during the ARRL DX contest that sounded very similar to those scenes you see on a typical DXpedition video. Though nervous, I was able to keep up and log accurately though those bursts largely because of all the practice I had gotten in previous contests.
Improvement needs to be a closed loop activity: you need to do something, assess your effort, make a plan to correct what you didn't do well, and then try again. Assessing your effort is pretty easy if you participate in one of the major contests run by the ARRL or CQ Magazine as they provide access to a UBN (Unique, Bad, Not-in-log) report. An article describing this Learning from Your Log Checking Report just won the ARRL QST Cover Plaque Award for September. The article is brief, but it provides some excellent advice such as record and listen to your on-air operation after the event to see what you missed. Use the log checking report to revisit those problem QSOs. See what went wrong. Did you miss that extra dit making an "h" into an "s"? Did you hear "J" and log "G" in that call sign?
To give you an idea of what is in one of these reports, I've included one of mine (so you can see all my goof-ups). I believe practice makes perfect but you also need to have an improvement plan that analyzes your shortcomings and tries to address them. And, like my little 100 pound DXpeditions, I have goals in these contests, too. For example, in the next major contest I would like to have no busted calls. We'll see how I do. In the mean time, here's the log from my QRP effort in last year's ARRL November Sweepstakes contest. By the way, this was SSB with my Elecraft K2, a low hung inverted-vee antenna, and a lot of grit. I may not have had the most competitive station for this contest, or indeed any contest, but doing your best with the working conditions you have is also excellent practice for lightweight DXpeditioning! OK. Here's the UBN report. I hope you, too, can learn from my mistakes. Enjoy.
