Here's an older (2016) listing of SSB Nets but it should still be pretty accurate...
OCC Caribbean SSB Radio Net 2015 - 2016
The OCC Caribbean radio net will be in operation again this winter from December to April as a minimum. This is not a HAM net so anyone with a SSB radio can join in. Getting the net started in December requires some persistence by the net controller to recruit contributors, so please listen and call until we establish a workable group after which it is self-sustaining.
0730 local time (1130 GMT) on most days usually Monday-Saturday on 6227kHz USB.
John & Christine Little have handed over to Simon & Hilda Julien aboard 'Barisa ' who intend to carry on the Net.
