[App_rpt-users] Jackson Labs GPS Device and RTCM

[Frederick Bray]

I am 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.

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.

Does it appear that these units would work? Has anyone experimented with 
this or similar units with the RTCM?

Thanks.
