Hi Everyone, I have two Lucent RFTG boxes in my workshop. The XO is a loaner. I'm curious if they will interface with each other or (most likely) they are a different series as the interface connectors on each have a different number of pins. One is marked RFTG-u REF 0 The other is RFTGm-II-XO Thanks in advance. Chris KD4PBJ

Chris, The RFTGm ("m" for miniature even though still a large box) is a later version of the RFTG line. The XO unit houses the GPS receiver which is essential for disciplining. Both boxes operate at 24 VDC and there is an interface cable drawing on line at KO4BB's web site. Never tried to hook them up together, but it might work. Maybe others here may know. Good luck with it. 73's Doug On Jul 18, 2016 12:52 PM, "Chris Waldrup" <kd4pbj@gmail.com> wrote: > Hi Everyone, > > I have two Lucent RFTG boxes in my workshop.

No, it does not work, unless you can reprogram the microprocessors. I speak from experience. The older boxes used a GPS receiver that reported up to 6 satellites. The newer boxes report 8. The messages that report satellite health have different lengths. If the micro reports an error in the message, the box goes into "flywheel" mode (aka holdover). The oscillators are undisciplined, wasting all of that GPS info. An external PPS signal, if you could couple it in, would be ignored because the micro won't even try to use it. Bill Hawkins Note: I can't reprogram micros with unknown code. -----Original Message----- From: Douglas Baker Sent: Monday, July 18, 2016 4:39 PM Chris, The RFTGm ("m" for miniature even though still a large box) is a later version of the RFTG line.

Thanks Bill. I can use the RTFGm-XO by itself though, right? I found a site with mods to extract the 10 MHz Signal rather than use the 15 MHz.
