Just got a newer version of the GPSDO from BG7TBL and it does receive the data fine with Visual GPS View. It seems like a neat program now that it is working. Too bad the other makes of Chinese GPSDOs won't work with Visual GPS View.
If the RS232 connectors can output NMEA sentences on one of the pins. Using U-Center from U-Blox works very well. Lot's of features.

without the proprietary oscilloquartz configuration manager software you wouldn't be able to talk to the ocxo anyway. the protocol does not appear to be documented. nor does the software appear to be available anymore.
I got hold of some documentation for the Star-4 (still checking to see if I can share it).
Interesting! Have you tried Lady Heather with other GPSDOs made in China? I've got 3 others that I can't get to talk with PUTTY, Termite, or Visual GPS. I haven't tried SatStat or GPSCon. I love the way the BG7TBL GPSDO communicates with Visual GPS.

Yes, Lady Heather now talks to pretty much all GPSDO, GPS timing receivers, NMEA receivers, GPSD, etc including those small Trimble/Symmetricom "UCCM" GPSDOs.
Attached is a screen dump of Lady Heather controlling the BG7TBL GPSDO via the Star-4 "management" port. It shows the unit doing its 4-hour self-survey after a power-up. Once it surveys in, it switches to position hold mode.
I wired a RS-232 level converter to the management port pins on the 26 pin Star-4 connector. The management port lets you monitor and control the device a lot better than through the NMEA TOD output on the RS-232 connector. One funky thing that happens if you use the management port is the TOD output switches from NMEA to Ublox binary messages.
It would be cool if someone stuck their GPSDO into a case with a front panel LCD, with that as the output being displayed.

Lady Heather runs well on a Raspberry Pi (also Windows, Linux, macOS). The standard PI LCD display (800x480) can work but is really a a bit too small to be effective. A 1024x768 screen would be a lot better. Linux and macOS use X11 as the display system.
It can work with NMEA, Trimble TSIP, Motorola, Ublox, Sirf, NVS, Z38xx (SCPI), Star-4, GPSD, etc devices or as a fancy clock display off the system clock and provides full control and monitoring/logging.
Sorry, actually MTK3339.
Too bad Lady Heather is not ported to QT. I have my raspberry pi 3 booting yocto. Going to try and see if I can get the native Lady Heather Linux version to compile.
I have not looked at the source code of it. I'm wondering how much effort would it be to port it over to QT?

I'm hurt, deeply hurt.

Would like to stick the gpsdo and a raspberry pi 3 into a nice case with a 10inch display. Have the unit boot directly into Lady Heather. I got my yocto image built. It boots in about 8 seconds.
