The June VHF Contest is the second major ARRL VHF contest of the year, the first being in January. The contest this year is the second weekend of the month, June 9th-11th. You can find a copy of the rules with all the specifics, here.
You will find most activity centered on 6M and 2M with the remainder of activity on 70CM and 1.25M. In certain areas, you will find people with equipment for the higher bands, 902MHz-10GHz, but I doubt there will be that much, or kind of, activity locally. You may want to try your hand with the various WSJT modes! But don’t forget our old friends SSB and CW.
Good Luck to All!
