The station is owned and operated by Gwy-Môn Media[1] and broadcasts on 96.8, 102.1 and 102.5 FM and online from studios in Llangefni town centre.

In recent years, MônFM's editorial content has been expanded beyond its primary Anglesey TSA (target service area) to provide ample coverage of the mainland county.

Following an RSL transmission on 87.9 FM for the Llangefni area in March 2012,[2] the station continued to produce online output before being granted a full-time licence in August 2013, allowing MônFM to broadcast across most of the island via a transmitter at Gwalchmai.

[5] In August 2019, OFCOM granted permission for MônFM to expand its FM coverage area by building two new transmitters at Penmynydd and Nebo.

[6] The station began broadcasting on 96.8 FM from the Penmynydd transmitter, targeting eastern Anglesey and north Gwynedd, on 6 May 2021.
