Hi, I am reviewing and expanding and for the NTPSec project < http://www.ntpsec.org >, a fork of NTP.
Among NTPSec's goals are a smaller, auditable, code-base; hence support for receivers last available in the early-1990s is being removed. I have been on this list for some years (thank you), but as I am in Singapore, I did not pay attention to the WWVB format change. I understand that as a result of the change, precision equipment may not be able to recover a usable signal from the new modulation scheme, rendering it useless for the sub-100 microsec disciplining. However, I am not clear if WWV and WWVH are still usable by commercially available equipment, or of such equipment is also obsolete now. I have read Wikipedia, the NIST pages, etc, and am still confused. Could someone summarise current state: 1. Are there commercially (or widely-used) receivers for professional use which listen to the WWVB signal? 2. Are there commercially (or widely-used) receivers for professional use which listen to the WWV(H) signal? A supplementary question: If you have your own homebrew for these signals, do you use them as a refclock for NTP?
