The transmitter primarily serves the central belt of Scotland.
Services from the site have already been interupted during the past week due to regular maintenance work at the site.
Now it has been confirmed that from 30th July through to the 23rd August, BBC Radio 4 on 198 LW in Scotland is liable to be affected by reduced power, although other transmitters making up the Radio 4 LW network will continue on air as normal.
