I was looking at GPSDOs about a year ago and settled on a Geppetto Electronics OH300, I have the OCXO version. It was $289.00 new and with an antenna attached is truly plug and play with my K3EXREF. With an accuracy of +/- 0.1PPB its actually much better than anyone really needs (+/- 0.1PPM @ 144 MHz is less than 1Hz). The customer support is great and at $289 its tough to beat! For more info here is their URL "

> A shiny new K3S has joined my Elecraft herd, though K3 #2545 is still going strong.? I have been getting confused looking at GPSDOs, and wonder if someone can recommend a plug and play (or close as practicable) GPSDO for me to buy.??
