[time-nuts] Oscillators away

Hi Bob,

Thanks for making these available to group members.

I could make use of either of your Rb, 10 MHz., osc's (17 or 18). I am in need of a high stab osc for my Amateur Radio microwave rover station. These stabilize the Tx/Rx frequencies in the transverters.

Best regards,

Dave Smith W6TE

Time-Nuts,

   I have a number of oscillators to give away.

The link to images, along with a few datasheets is below:

https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapp.box.com%2Fs%2Fhq22jbe3jdfzhfqnot1hxcvjqwdooj6m&data=02%7C01%7C%7Cf13503bc38694d036d9608d6296f220c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636741954614227721&sdata=6EedT8y4j28OaqaLkJG3RIelonoml90SOhGXfRN4uC0%3D&reserved=0

Note that there are two pages in the Box.com folder.

I'm willing to part with them, one or two to a customer, in return for the cost of shipping.

For myself, I'd prefer they to go to those who will use them.
So, if you want one, please tell me how you plan to incorporate it into your timing system.

If you have questions about individual oscillators please send then to the group because the answers can then be shared. The moderator can decide whether this is a viable process.

Other than the moderator, please DO NOT not contact me directly for now. In a week or so I'll send a message to the group to begin the request process.  This should allow everyone time to consider their needs and possibilities.

Some of the devices are valuable and I may share your requests with the group or individuals in the group as a sanity check for your request.

Again, please don't contact me directly until everyone has a chance to review the list and I send the post to begin.  The selection process will be off-list.

Thanks,

Bob Martin

  automatically to 5 or 10MHz reference. Locking is
  mixer/integrator based. Used in 5MHz steered DDS's.
  If you want one you will need to have be explicit
  regarding your application.

Osc 12
