Jack Russell was playing recordings of Radio Caroline 319 on Weekend Music Radio on his show this week.
N2MLP could have heard the rebroadcast via Shortwave Gold on 6160/3975. This show was due to run from 2100-2300 UTC (Saturdays)
I'm listening now on 6290 (20 Aug, 0937 UTC). Lots of clips with "Caroline 319" IDs from 1983
