[time-nuts] Oscilloquartz 4532 GPS receiver

[Tom Knox]

I saw that on eBay, it is great to see a fellow Time Nut won it. I would think Phase Noise is excellent with the 8663, although I would prefer a version with discrete SMA's on the outputs.
I look forward to your impressions after further evaluation.
