[time-nuts] Cheap GPSDO with OCXO from aliexpress

[David G. McGaw]

The BG7TBL design (that happens to be the designer's ham call sign) is 
also available on eBay in various versions.  I do have one. Seems to 
work.  The problem I have with it is that it only outputs NMEA from the 
GPS receiver.  There is no lock info from the serial port.
