I have a AT&T /Lucent 10 Mhz reference Oscillator F/S Part number ED2R849-31 G4 I can send pics if interested. I got this a long time a go and it has been in my garage for a while. Now that I got my Trimble working I don't think I'll ever do anything with it. So I'm offering it up here. Contact me off list.
