Get Ready for the Upcoming ARRL September VHF QSO Party


September is here, and according to ARRL Contest Branch Manager Sean Kutzko, KX9X, that means the VHF bands are getting a workout. "If you've never experienced the fun of VHF+ operating, the ARRL September VHF QSO Party is a great place to start."

With many HF radios now offering at least 6 meter SSB/CW capabilities -- and some offering 2 meters and 70 cm as well -- any amateur with a Technician class license or higher can experience long-haul communication on the VHF bands," he said. "Getting on the VHF bands is simple, he said. You need a radio that can transmit on both CW and SSB." When operating on VHF, Kutzko explained that your Maidenhead grid square is the common geographical information exchanged.

While there will be some contest activity on FM simplex (especially near large population centers), Kutzko said that most long-distance VHF+ QSOs are conducted on CW or SSB; that means horizontally polarized antennas: "A dipole for 6 meters is only 9 feet, 4 inches long and is an easy construction project," he explained. "Try to get the dipole in the air as high as possible, but even 15 feet off the ground will make some QSOs. If you have an antenna tuner that can handle 6 meters, you can try loading up another of your antennas on 6 meters with reasonable success. For 2 meters and 70 cm, a horizontal loop will work nicely for SSB and CW contacts." You can find plans for simple VHF antennas at the Technical Information Service area of the ARRL Web site, in the Antennas chapter of The ARRL Handbook, or in the VHF and UHF Antenna Systems chapter of The ARRL Antenna Book.

Kutzko advises that there are a few things to know about operating on 6 meters: In the US and Canada, there is a "calling frequency" on 50.125 MHz USB. Many stations monitor this frequency to listen for band openings. Stations can call CQ on the calling frequency; if somebody answers, the stations will find a new frequency on which to conduct their QSO. It is considered poor etiquette to monopolize the calling frequency for QSOs.

Most SSB activity will take place between 50.125 MHz and 50.250 MHz. If conditions are exceptional, Kutzko said you may hear signals above 50.250: "CW signals can be found from 50.100 MHz to 50.080 or so. The frequencies between 50.100 and 50.125 MHz are a 'DX Window,' meaning it is reserved for QSOs between W/VE and DX stations. Please do not make stateside-to-stateside QSOs in the DX Window."

Because VHF+ antennas are relatively small, Kutzko said that many amateurs operate from portable locations, such as a hilltop or a campground. Others operate the contest as a "rover," operating from their car or truck while transmitting from multiple grid squares over the contest period. "Tracking rovers during the contest is almost as much fun as the contest itself," he said.

The ARRL September VHF QSO Party runs from 1800 UTC Saturday, September 12 through 0300 UTC Monday, September 14. Be sure to use those extra bands on your transceiver and get in on the fun you've been missing on 6 meters and up!
