Hi Robert,


As far as I know, the NixiSat will support NMEA. I there are a few members of this board who have upgraded their NixiSat's with a GlobalSat GPS unit similar to what you used. Also, the GPSII, NixiSat and NixiChron are all the same designs just in different packages.

I like you're idea of using the BNC and grabbing the +5V from under the PCB somewhere. That would be clean.

I have the schematic for the NixiSat, I can send it to you if that would help? Let me know and I can send it to you.

Hi Greg,

An Oncore footprint adapter would be powered by the +5 provided at the NixiSat Oncore socket... no need for any other tap into the NixiSat pcb. Think two wires from the BNC (data and GND) and a third (GPS data) routed inside from under the clock... The three wires terminate in a 1/8" stereo plug plugged into the adapter board. Better still, include an OSX jack in parallel with two lines of the 1/8" jack on the Oncore adapter. This leaves the installed BNC-OSX pigtail intact.

I'd be very interested in the NixiSat schematic... bob home at pacbell dot net. Let's take this off-line for a bit?

Hi Robert,
I've got 2 of the GPSII clocks, some of Jeff's earliest, and I'd be very interested in obtaining more information (all the gory details) about how to go about replicating this wonderful fix. Thanks!

Best wishes
Bob
