Simplex Test

The next project will be a 75 meter “simplex test” to compare antennas.

The simplex test measures communications distance, both one-way and two-way, between every participating station.

  • Everyone transmits in order of a list created at check-in on the repeater.
  • Participants write down the callsign of everyone they copy solid enough to have a contact.
  • We return to the repeater to exchange reports
  • Participants must stay through the entire test, otherwise you will not be counted in final tally


To be fair to everyone the simplex test operates under the following rules:

  • Everyone is welcome to participate but they must stay through the entire test to be counted
  • Participant transmitter and receiver location must be the same as the FCC listed address, or you must supply the exact physical address
  • The reports must be honest, They must include the callsign or some identifying trait (e.g. “I heard Jeff in Thomaston” ) of stations copied. We will clear the ID up on the repeater so don’t worry if you miss a callsign.
  • If you need a repeat at any point or if the emcee misses anything please speak up immediately!


The goal of simplex tests is to compare our signals and motivate people to improve their systems. The simplex test is a form of friendly contest, much like our Wednesday night trivia.
