I've always wondered if an SL5 will work too. Ass-u-me-ing, but if an SL5 will work on a Phase III, it should work better with this. If I understand correctly, all the HD is on the birds parked close to each other and the 119 just has some SD Locals and carries some SonicTap music. The 110 carries nothin I know of or have access too.
BTW, the mod doesn't have to be SWM. Might be a consideration as that requires another 12vac outlet in the boonies.
