When colour UHF television began in 1969, the nearby BBC owned station at Rosemarkie was chosen over Mounteagle to carry these broadcasts. Both the UHF and VHF services continued in tandem until 1985, when VHF television was discontinued in the UK. At this point, Mounteagle ceased broadcasting television services entirely.
In 1982 Mounteagle was chosen as the site of the first commercial radio broadcasts in northern Scotland, with Moray Firth Radio taking to the air on 23 February of that year.
In 1996 transmitters for Classic FM were added, and then later in 1997 Mounteagle began broadcasting television services again, when transmitters were installed for the launch of Channel 5. Digital switchover occurred in the Inverness area in October 2010, and at this point the Channel 5 service was discontinued, and now broadcasts digitally from the nearby Rosemarkie transmitter site.
More recently the station has become the first in the area to carry digital radio broadcasts, with the addition of transmitters for Digital One, BBC and Score Inverness.
