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?

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.

[] David VanHorn Lead Hardware Engineer ============================================== 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.
