GPSDO - from Radioshackus - China.

Bought a unit for keeping as an reference - 10MHz or 1PPM. My unit is built on the Trimble base doesn't seem to work as stated - tested. I followed the pdf connecting it and typed help... - No response from the unit. The unit when powered on with the antenna connected started with the leds On and Alm1 - after one second the On moved to Lock -and it have stayed there since.

Now... I was a bit hasty and overly harsh. Hence the edit. There is a solution to this I'm sure of. I will look into it during the weekend.

Which GPSDO? The Timenuts list Time-Nuts -- Precise Time and Frequency for Amateurs would be the best place to find out about it. You can search the messages online somehow https://www.mail-archive.com/time-nuts@febo.com/

Thanks Demian for the tip. There are many different boxes all more or less the same.
The one I bought and got working was one of these http://rover.ebay.com/rover/0/e11051.m43.l1123/7?euid=f77ceb1b549f4e959e07b647cccf3c15&loc=http%3A%2F%2Fpages.ebay.com%2Flink%2F%3Fnav%3Ditem.view%26id%3D182046512214%26alt%3Dweb%26globalID%3DEBAY-US%26referrer%3Dhttp%253A%252F%252Frover.ebay.com%252Frover%252F0%252Fe11051.m43.l1123%252F7%253Feuid%253Df77ceb1b549f4e959e07b647cccf3c15%2526cp%253D1%2526exe%253D13926%2526ext%253D35632%2526sojTags%253Dexe%253Dexe%252Cext%253Dext what a terrible URL...

I looked at them. Probably the 10 MHz and the 1 pps will be good, just not timenuts good. I suspect some guys DIY GPSDO bootlegged on a large scale.

I have a Thunderbolt (from when they were cheap) and an Arbiter GPSDO with a Wenzel oscillator that is very good. But they are overkill for audio.

The Tbolts are about 400$ when I looked - way over my budget. I just use it as an 10MHz ref so 140$ had to be enough.
