Yongnuo RF602s and Sunpak PF30x

A quick Google shows the PF30x as having well documented issues working with wireless triggers of all sorts.
 
Most flashes with a trigger voltage under under 12v will work with the RF602, however there are one or two others (the early Nissin Di622, for example) which won't. As far as your Sunpak goes, they seem to have problems with triggers in general.
