10MHZ Output Sine Wave GPS Disciplined Clock GPSDO + GPS Antenna+ Power Supply

Excellent product. This GPSDO produces a stable 10.000.000 MHz sine wave signal as well as a 1 PPS timing signal. It has a RS232 port and works well with programs such as "Lady Heather" for tracking GPS birds. The GPSDO is capable of tracking 14 satellites with the included antenna placed in a location which will give it exposure to most of the sky. The unit is small, runs on 12 VDC, produces little heat. Compared to my old cell tower GPS unit, it is a major improvement.

I've been selling and making precision oscillators including rubidiums for more than 40 years. This is the best product for price ever! My rubidum signed out a few weeks ago and I have been using an OCXO as my reference standard. According to the GPS (the satellites have cesium oscillators) my OCXO is 0.04 Hz off frequency at 10 MHz. Not too shabby. The GPS antenna is just on the bench a few feet away from a window.

The clock output works as intended, I measured sine wave at 10.003 MHz as the clock output (which I did not measure using precisely calibrated equipment btw). I would definitely recommend this as a cheaper alternative to other GPSDO products.

No manual, no instructions. Chinese web site printed on the label appears to be a grocery outlet. Its the same Chinese piece available on ebay for considerably less, but to me worth buying from Amazon if if I want fast delivery and the certainty of return/refund had it been defective.

Good value for a device that works as described. Easy setup.

Just received the device. Seems to lock in a reasonable period of time. The downside it seems to be putting out a ~16MHz clock, not 10MHz.

Been working now for over a week and I am very happy with the quality and stability of the unit. Glad I purchased this!

This frequency standard keeps my signal generator and frequency counters calibrated to one another. Really helps in aligning older amateur radios.
