The ARRL September VHF Contest is this weekend (1800 UTC September 14 to 0259 UTC September 16), providing a chance for radio amateurs of all levels to experience contesting on our higher bands. This event is markedly different from the June VHF Contest, due to the heightened potential of excellent tropospheric conditions. Activity centers on 50.125, 144.200, 222.100 and 432.100 MHz. These are calling frequencies, however, and contest participants should avoid monopolizing them.

On 6 meters, the most popular band, most SSB activity will take place between 50.125 MHz and 50.250 MHz, and CW between 50.080 MHz and 50.100 MHz. The frequencies between 50.100 MHz and 50.125 MHz are considered a “DX Window,” for contacts between W/VE and DX stations, so avoid US-to-US contacts in that part of the band. Even FM operators can get in on the fun by competing in the FM-only category. FM simplex activity on 2 meters will center around population centers. Remember: ARRL General VHF Contest Rules prohibit contest operators from using the national simplex frequency of 146.52 MHz to make or solicit contacts. Operators should avoid camping out on traditional calling/simplex frequencies. Check the band plans for details on all bands.

Rules and entry forms are on the ARRL website. All logs must be e-mailed or postmarked no later than 0300 UTC on October 16, 2013. Electronic logs are preferred. Send paper logs to September VHF Contest, ARRL, 225 Main St, Newington, CT 06111.
