thinking of acquiring a couple of the Jackson Labs M12M
replacement receivers to use with my RTCM units. It appears
that they might greatly simplify the process obtaining a GPS
derived 1 PPS signal, especially for temporary / portable
repeaters that require voting receivers. They are currently
available for under $200 per unit, shipped.<br>

These were designed as a retrofit for a specific earlier GPS
receiver but they appear to be potentially useful to supply at
least the 1 PPS signal required by the RTCM. They might also
act as a frequency standard for simulcast, although they may
not have the oscillator required to provide a stable frequency
source in the event of loss of GPS signal.<br>
<br>
Does it appear that these units would work? Has anyone
experimented with this or similar units with the RTCM?<br>
<br>
Thanks.<br>
