Re: [time-nuts] Alternatives for Thunderbolts

[David J Taylor via time-nuts]

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?

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_id=272

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

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

Cheers,
David

[time-nuts] Alternatives for Thunderbolts

[Mark Sims]

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=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.
