Hello Nuts, I have a Symmetricom 3500 shelf minus GPS receiver. The 3xxx series looks like it uses a proprietary IF interface that shoots 18V up to the GPS receiver, and I don't know what comes down. There has to be data though since the box can report lat and lon. Don't know if there is also any frequency reference signal, but based on the function of the box you might think that there is. The physical interface is just a single piece of coax.
Does anyone know what the 'proprietary IF interface' is? Does anyone have an extra GPS receiver laying around that they would like to get tid of (or where I could find one) for these boxes? Thanks in advance.
