GB3OM is just one of the repeaters run and maintained by UKFM West Ulster Group, commonly known as the West Tyrone Repeater Group, the other repeaters which the group run and maintain are GB3WT and GB7WT.

GB3OM started off as a 70cm analogue repeater on  433.375MHz (RB15) with a 1.6Mhz + Shift, this then changed in 2012 when GB3OM was allocated a frequency change with a wide shift and can now be heard on 430.950MHz (RU76) which is still current today, the latest change came to GB3OM when it was allocated Dual Mode working and is now a DMR/Analogue repeater.
