Re: [time-nuts] RFTGm-II-Rb - can you gps discipline it without the XO module?

Hi Alan,  I haven't seen this behaviour yet, but then I have RFTG shut off for a couple of months since. 7168 is dividible by 7 and the result is 1024. You know the gps week wraps over from 1023 (0x3ff) to 0. Perhaps what you see is the consequence of some software workaround of this problem,

Hi Alan, sorry for my misleading comment. What I meant was the RFTG will need @@Ea messages coming from the UT. They contain the necessary gps data for the RFTG to accept the pps pulse. You initiate on the UT by sending it a @@Ea request. This has to be done for example  y a PC running the

Alan, wrong manual, the UT doesn't talk sirf as far as I remember. Although it can do NMEA this is not what want. Try to find a manual for the motorola Oncore receivers, the commands and messages I mentioned are specific to them. Have fun, Guido Von Samsung Mobile gesendet Alan Kamrowski II

Been there, done that.  The RFTGm-RB can be disciplined if you connect the pps and the gps data stream coming from a motorola Oncore.  Regards Guido Von Samsung Mobile gesendet Rex r...@sonic.net hat geschrieben: I don't think the rubidium module for these systems can be disciplined. I think
