Fort DeSoto Park ?

Can't seem to find any information about where to listen to Fort DeSoto Park.
Are they on the county or state trunked systems or do they have there own frequencies in use?
Thanks for any information.

traditionally there has been activity referencing areas/beaches/wrecks in ft desoto on the parks tgids in the pinellas county public safety system, and also simulcast on the pinellas county public safety p25 system. don't know if they use conventional, as well. the database references parks "c" as de soto.
