Here is an update on the 57964-60 GPSDO board that I bought. After figuring out what it needed for power (it is definitely 5.6-6.0VDV) and communications as I previously posted, I built it into a nice enclosure and fed the 10 Mhz output into my modified Tbolt so I could get a graph of the output. The graph doesn't show the first 10 minutes after power-up because the 10 Mhz isn't active until the GPS locks. It looks to be a pretty reasonable GPSDO in a small package. The labels on the front and back panels are just in the photoshop pictures shown in the link below and I haven't made the physical labels yet. Note that I did remove the on-board LEDs and reset switch and then mounted replacements on the front panel where they would be useful.
I have no idea what equipment these GPSDOs were used in so I have no idea whether there is going to be a lot of them appearing for sale in the future or just a few. I hope that if there are a lot of these available someone with the knowledge can make a Lady Heather type program to see what the thing is doing. Using a terminal emulator program works but is really clunky. http://i906.photobucket.com/albums/ac262/rjb1998/GPSDOx4_zpsu2cugpwg.jpg -Arthur _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
