    Does anyone know if you can or how to upgrade an EF Johnson 51SL for TDMA?

    need to call johnson and ask them for the opt package that has that option. cost you a couple of buck if not one of the locals may help you, put the radio into upgrade mode and go for it. actually pretty simple.

    I didn't think the 51sl could do TDMA. The 5100ES can with a board swap.

    the 51xx series (and 51sl) will not do TDMA. The VP600 and 53SL are the radios slated for TDMA Phase II upgrades.
