Hi gang I have an opportunity to acquire a Johnson repeater, (free), since I have lond since lost my Johnson key, I am not sure what it is yet, I have a feeling it is a CR1010, all I know at this moment, is, it is set for 463.875/468.875, it was originally licensed in 1998, and renewed in 2003, Is this unit convertible to 440, if so how hard would it be?
