The Smooth Radio network broadcasts on a number of mediumwave frequencies throughout the UK. Smooth Radio is not the most exciting station from a DX-ers point of view playing only pop music and with very little or no local programming. Local commercials and local traffic reports can, however, be heard on the stations from time to time making it possible to distinguish the different transmitters from each other.
At Lista in February 2017 I had a very good signal from Smooth Radio Hampshire on 1557 kHz one morning with local traffic and weather reports. This was via their mediumwave transmitter in Southampton listed with a power of 500 watts. Originally, this station was known as Ocean Sound. Broadcast Engineer Steve Ord confirmed my audio recording of the station with an e-mail today.
