assistant: Hi, Scott;
Ok, when I'm wrong I admit it.  I wuz rong.   :-{
Let me rephraise that.  The Handbook I had back in the 50's documented
that time code pretty thoroughly, and I DID have an old Hallicrafters
S-22R that could pick up everything from 110 KHz to 18 MHz, so I heard
WWV/WWVH plenty of times, and heard the "buzzing" which was documented in
that old Handbook.  But at this time the only HF RX I have is the HF
tranceiver wich does not cover ANY of the WWV frequencies.  (I do pick
up CHU occasionally on 3.330), so I haven't heard WWV/WWVH for about 15
years.  Since the later (1979) Handbook makes no mention of that encoding,
I could only assume that it was no longer there.  (Maybe I should send a
nastygram to the ARRL to tell them go get that info back in there?)  <G>
Also, just recently I was reading an article about one of the newer
clocks, telling how it was controlled by WWVB, which I have known about
for over 30 years.
The keyword there is "similar," not "same."   ;-}
OK, your docs say it receives 5, 10 and/or 15 MHz, I can't argue with
that, can I?  Pobody's nerfect.   :-}
That sounds like a LOT of fun, (I don't think!).   :-/
I'm sure of it!
