[time-nuts] KS-24361 REF-0 standalone

Synergy GPS makes an SSR-6Tr board that speaks Motorola binary and would probably work in the KS-24361.  It's on an M12+ sized board, so you'd also need their adapter board to fit it in.  Their SSR-M8T board would probably do the same thing but using an LEA-M8T receiver.  I believe they're selling their older SSR-6Tr boards at a discount as they update their product line.  I haven't tried this out, though.

I went back to the Time-Nuts archives, and noted that a modern GPS receiver to replace the Motorola Oncore UT+ (8-channel, timing) in the HP Z3801A was discussed 3 years ago (Sept, 2012).

Bob Camp suggested something like a uBlox LEA-6T and a PIC on a drop in board to fit in the Z3801a.
"Let the GPS work with lots of sats and use the emulator to hide the extras from the 3801.  Initialize the gps from the PIC and more or less ignore the init commands from the 3801.  Sounds like a pretty involved project."
The proliferation of smaller, more capable GPS receivers, at lower price points -- as well as powerful processors -- turns the exercise into software for command translation.
