Hi Alan, the one I used was a Oncore UT. The message needed for the RFTG is @@Ea...... once a second if I remember correctly. Note that the RFTG doesn't talk to the UT, it just listens, so you will need to initiate the messages somehow. There's also some windows diagnostic software for the RFTG on ko4bb's archive. Have fun Guido

Regards Guido I've pulled it apart and the board does show a connection to the EXT C-FIELD. That trace runs to a jumper labeled A C B and currently C B is shunted. Any particular Motorola oncore model required - I see a bunch of them on Ebay...

Von Samsung Mobile gesendet Rex <[email protected]> hat geschrieben: I don't think the rubidium module for these systems can be disciplined. I think they were only intended as a backup if the XO section or GPS failed. The XO section does discipline but I don't know the details. I'm not sure of the model number, Lucent had several variations on the same theme in that time frame. I had one of the rubidiums that may be the same as yours. Trying to trace out some of the circuits, I found that the EFC on the LPRO connector was not being used at all.
