Beyond FM:  Contesting

By Jim Aguirre, W7DHC

One of the best times to check out the bands above 50 MHz is during a contest. That doesn't mean, however, that you have to be a polished contester or even particularly interested in contesting. Simply put, during contest periods there will be more concentrated activity on these bands than at any other time.

Don't worry if you're not a contester; the only thing you'll need to know'along with your call sign'is the Maidenhead grid square you are in. Most club members are in CN87; a few'those living East of Issaquah'are in CN97. If you're not sure of your grid square, ask any of the VHF operators in the club and they'll help you find out.

The contest exchange is usually just your call sign and the grid you're in; e.g. 'N7CFO copy CN 97 from W7DHC.' You will need to copy the same sequence of information to make it a valid contact. That's it, but be aware that unless things are really slow at the time, most contesters aren't likely to pause and 'chew the rag' very much, so contacts will be short.

The first big event of the VHF/UHF and microwave contesting season has just passed'the ARRL June VHF QSO Party. No problem, however, as there is still a lot of action to come in the next 3-4 months.

There are basically three types of VHF/UHF and microwave contests; standard, sprint and cumulative. Most contests are of the standard variety and are conducted over the course of a weekend. They generally begin at 11:00 am local time (1800Z) on Saturday and run through 8:00 pm local time on Sunday (0300Z Monday).

Sprint contests are much shorter in duration'usually 4-6 hours or so'and are often scheduled on weekday evenings; e.g. 7:00-11:00 pm local time. Most sprints are single-band events.

Cumulative contests are usually reserved for the high microwave bands or specialized modes like EME ('moonbounce'). Here, the contest period may stretch over a period of weeks. The reason for this type of contest is to maximize the possibility of good propagation on these specialized bands and modes.

Here's a list of known VHF/UHF and microwave contests scheduled in the next four months. There may be other local contests as well.

(Editor's note: The dates listed below are for previous years. The actual dates for the current year will vary but generally will be around the same weekend.)
