I'm looking for two more receivers to implement "Pair and a spare" redundancy for our engineering lab and production.

Are these below compatible with Lady Heather?
Any thoughts as to overall quality etc?
Any other suggestions?

We have used the first one with good results two and three are probably the same and on closer look I would stay away from them. The ublox is not even a timing receiver I have done stuff like that on a 2 by 2 inch board calling it a GPS PLL. Number four  most likely like 2 and 3. Get the first one, also best price.

I've been happy with these:

https://www.ebay.com/itm/10Mhz-GPSDO-OSCILLOQUARTZ-OSA-OEM-GPS-GPSDO-10MHz-1PPS-STAR-GPS-Clock/262861459973?hash=item3d33c39205%3Ag%3AsbYAAOSwh2xYAjrp&_sacat=0&_nkw=oscilloquartz+gpsdo&_from=R40&rt=nc&_trksid=m570.l1313

They are not nearly as tweakable as the Thunderbolt, but the GPSDO inside is made by a company that seems to know what they are doing. The 8663 DOCXO used in the ATDC version is thei highest spec'd version.

==============================================

David,

You might look at the Leo Bodnar boxes if you want quality and support in a
modern unit:

NTP server with a PPS/1 MHz/10 MHz output:
http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=272

450 Hz - 800 MHz GPSDO with either 1 or two outputs:
http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=234
http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=301

I'm using all three here and there have been no problems.

Cheers,
David
