You could always transform this from a hardware problem to a software 
problem. Take the output of your GPSDO, divide it down to somewhere 
inside the audio band, feed it to a spare input on your USB sound 
card and have software track this reference and correct the received 

LART. 250 MIPS under one Watt. Free hardware design files.
