Radio Dublin can be traced as far back as 1966 with sporadic transmissions. 

The earliest recording we have in our collection referring to Radio Dublin is from Radio Galaxy in around 1969/70. 

As Tony Boylan signed off at 1:30pm, he mentions that listeners might want to tune to Radio Dublin on 217m.  By 1971 the station had moved to 253m / 1183kHz and became very regular, expecially in 1971 and 1972.  The operators at the time were Ken Edwards, Prince Terry and Mark T.  Radio Dublin made one of many 'closedowns' in late 1972, when Post Office investigators began closing in, not just on them, but on other free radio stations in Dublin City.  At this point, the plans were to transfer to the shortwave 49 metre band.  It is not known whether these transmissions took place in 1973, but later on that year Radio Dublin returned to the airwaves on 253m, with Prince Terry at the helm.
