This March 24, 2019 from 6pm – 8pm local time will be the Spring version of “Light up 2 Meter Simplex”. the aim of this event is to get on 2 meter simplex and chat with other hams. A common place to start is the national calling frequency of 146.52 Mhz (no tone and no offset) Also any other simplex frequency is great as well.
