I haven't been on this topic in a while, and was wondering if sawtooth correction was added to this GPSDO?
I built one from a friend that was based on Lars', had dual EFC DACs, sawtooth etc. and it did a good job with HP 10811s, symmetricom sprinter series, and an X72 Rb I have. I brought it out the other day and promptly blew up the arduino by attaching the received signal from the GPS directly to it without using a voltage divider. Now I can't recognize the arduino or reprogram it, and Amazon let me down on overnight shipping. But then I started wondering if this DO had ever been updated with sawtooth and maybe start here if there was more support.
Using the other GPSDO, I had planned to take the DACs out and send the tuning word to the X72 over serial, but I ran out of serial ports so I would have to rewrite some of it and setup another software serial port. I planned also to convert it to an STM32 board so I didn't need a PC to monitor it. I want to shut down my two lucent GPSDOs and just run the X72 until I repair my Cesium (I have another tube to put in it). The two lucent boxes take over 100w of power to run and at .40 per KW hour, that's not cheap.
Thanks
