Regarding the ARRL Phone Sweepstakes, I enjoy this one as it's one you really need to work at working all sections besides trying to make as many Q's as possible. However, after awhile, unless you're a big gun, and are able hold a frequency for a duration of time, you tend to run up against dupes. I would like to see the contest modified to allow working the same station on multiple bands as is allowed in so many other contests.
