Have two unids on 6300 Khz and 6327 Khz at 1340 Utc. 6300 Khz plays some rock songs of the 70th and 80th and Oldies. Strong signal SINPO 43433, I doubt it is Radio Rainbow, there is another station in the background. 6327 Khz played some pop-music and dutch music and faded out or signed off a few minutes later.
