Stockholm Radio is the sole commercial coastal radio station in Sweden operating on MF from five transmitter and receiver locations around the coast. Karlskrona Radio (SAA) & Tingstade Radio (SAE) are both Naval coastal radio stations.
"All of the general purpose MF Telephony/DSC transmitters are Standard Radio SST490 0.8 kW solid-state SSB/ISB types feeding vertical resonant radiators"
