Default WWV and YVTO on 5 MHz

At my location on the east coast of the US, I get semi-reliable
reception of WWV on 5 MHz through most of the night.

(See my WWV usability charts at

http://www.trailing-edge.com/~shoppa/wwv/

for propogation/reception conditions.).

But the 5 MHz signal often "sounds" different than the 10, 15, and 20 MHz
broadcasts. There's an additional beep that seems to come once
a second, and this is sometimes audible when WWV isn't heard at
all. Is it possible I'm picking up YVTO (also a time station at
5 MHz) from Venezuela? I'm not sure I've ever heard a Spanish-language
voice announcment, but presumably the modulation on the voice is less
than the once-a-second beep. The beep seems slightly out of phase
compared to WWV.

Are there any other 5MHz once-a-second-beep stations that might be
audible from the East Coast of the US? Isn't there a Chinese time broadcast
on 5 MHz? But I doubt that I'd be hearing it here on the East Coast. What's
the format of the Chinese broadcast?

It is possible that you're receiving YVTO. Try listening in SSB to see if you
can pick up an ID, which usually lasts quite a bit longer than WWV's.

TS,

A second alternative is that you may be hearing WWVH ? ? ?

This list is advertised as possibly out of date, but still may be
helpful to you:

http://www.ac6v.com/standard.htm

It shows a number of stations on 5MHz that might be audible on
the East Coast.

My best catch was once on 10MHz when I heard four stations at
once: WWV, WWVH, BPM, and JJY.

It's almost certainly YVTO. It's been there for years. I tuned in a
couple weeks ago and I was very surprised to hear YVTO off-kilter with
WWV. Maybe YVTO keeping UT1, which is about a half-second off of UTC
right now?

Could be, I agree that it sounds off-kilter. There's also supposedly
a Chinese station (BPM) that for half the hour beeps with UT1 and the
other half beeps with UTC:

Although it seems far more likely that I'm getting Venezuela on 5 MHz
at night than getting China.

It's been a while since I heard the voice announcement, but you should
hear it sometime between the 45th and 59th second, male voice,
"Observatorio Naval Cagigal, Caracas, Venezuela. A la oida las horas
seran (x) horas, (y) minutos, cero segundos".

I am In Wilmington, NC and will tell you that it is YVTO Caracas. I
hear it about 3 s-units below WWV. BTW, the reason the tones are out
of sync with each other is the propagation path (the time it takes for
the signal to reach your reciever. I have never heard the chineese
service from the east coast. Only VNG at 16000khz from Australia which
is now silent key.

Oh Yea, forgot about CHU. And if memory serves, there was a medium
wave time station at 740khz but I had to be in south Florida to hear
that.
