[Hammarlund] Hammarlund Restoration & Noise Level & TIME

[Richard Knoppow]

    I spent much of my professional life in network broadcasting 
and much of the rest in electronic metrology and have the habit 
of keeping track of time.
    BTW, somewhere I remember reading an article on figuring out 
the propagation delay applying to WWV and WWVH. WWVB, and the 
late, lamented WWVL are virtually all ground wave to the 
propagation time is fairly stable (was phase stable on VL) which 
it is not on the HF stations. For accurate time the HF stations 
must be averaged over a long period of time, days at least. 
Essentially cycle counting over a very long period. The 
transmitters are controlled to a very accurate standard.
     Also, details of antennas are available on the web.
