Using various GPSDO boards with 1PPS signal for locking 10 MHz reference sources,
or other  RF reference signals, such as ProgRock from QRP Labs,
for use with weak signal digital modes such as WSJT/WSPR, where
there is requirement for high stability and frequency accurate radios.

If you looking for 1PPS output, you need to look for boards that have
the Ublox NEO-6T or NEO-8T chip, or have the Telit JF2,
or a Trimble 36576 (as used on the SRM9000 Dispatcher board).
