Is an experimental station
granted by the FCC to test
digital AM BCB "voice" modes. I have
more info but am having
computer problems.
You can google it or look at the
various monitoring blogs.

Interesting stuff. I'll be listening, time permitting. I'm interested in the freeware Ham digital voice modes. New York to Ohio is do-able.
I've only scratched the surface with FreeDV. Using an SSB receiver and FreeDV software you can receive this digital voice mode.
Just tried 1750 from indoors with a 1-meter whip... nothing there.
Given that it's a digital station, would anything be audible on a plain AM-SW receiver?
It was fun anyway.
I'm in CT, not too far from
any part of NY.
I seem to have missed them.
My monitoring set-up isn't fantastic,
but it's somewhere in the "OK" to
"pretty good" range. I have heard
1 kW AM stations from California, about
3000 miles from here.
Little bits and pieces I have
heard say they are having
antenna problems. So maybe
they are off and intend to come
back on.
I guess a bunch of us will be monitoring
1750 and (oh yeah) 9395 kHz - the other
thing of interest. Unfortunately I have to
run.

P.S. I ran back. Carl, they were doing
morse code and AM. I think if they were
digital you would hear something (?)
Have you heard DRM - Digital radio Mondiale
at all? The BBC used to transmit it on 3955 kHz.
It was audible in the U.S. during the wintertime.
It just sounded like a bunch of noise.

As of Friday 12/12/14, word is that WH2XDE/1
will be testing Saturday evenings (for
us in the U.S.) But to make it less confusing,
in UTC that is Sunday 0000Z to 0400Z. So, for
me, for instance, here on the east coast, I guess
that's 7:PM to 11:PM Saturday evenings, local EST.
Anyway, they will be 1kW on 1750 kHz AM, and
digital modes, with less transmitter power.
I haven't heard them yet so I don't know what to
expect. I will give them a try tomorrow night.
I would think 1kW on 1750 kHz which is clear,
(except for occasional fishing beacons in that part
of the spectrum, and the beacons must be pretty weak)
- well - yeah, anyway so 1750 kHz should be good for
quite a distance. I don't know where Victor, NY is.
I will have to look it up.
So you guys who like this sort of stuff and
have fairly good AM receiving set-ups, check
it out. This is a rare one.
Excuse the cruddy grammar, I'm trying to type
this while I'm doing something else.
Very Best Wishes,
Bruce
I took a quick look at a map.
Even though they are in NY, they
are farther from me (CT) than I thought.
It's not like Victor, NJ is near New Jersey
or anything like that. (New Jersey, New York,
and Connecticut all come close together at a
point while is refered to as the "Tri State Area.")
It's not near there. It's in a part of NY which is
situated some distance up from the central part
of PA. OR, better said, a few hundred miles up(?) from the
central upper PA/lower NY border.) Well - I'm not good
with maps. I guess the ionosphere will determine
what happens with the signal anyway.
Good luck trying to hear it.
Bruce
Neil, if you were able to try hearing
it on your military receiver (it's a
version of the R-390A, isn't it?)
I would think you would be
able to hear it.
Bruce
Bruce, and everybody, I promise to eventually setup a good shortwave reception antenna to really play a part in the fascinating transmissions that keep happening.
Even with my simple-dimple indoor 1-meter telescoping antenna I try...
At 9:15 PM CST I hear only noise at 1750 kHz, but I have not done a time conversion to know if it's the right time to try. I'm way to careless to bother with that.
Hi Carl and everyone else.
If this is a digital transmission you will not receive it on an analog receiver.
You need a digital to analog converter to hear the audio. You will only
hear white static other wise. It like when Satelite went from analog to digital
signals they should signal going from a picture to pure white static on the
screen on their commercials if you did not get a digital receiver.
you are going to need a shortwave receiver capable of receiving digital signals.
Google shortwave receiver receives digital signals.
This is what you will need. The older shortwave radios will not work.
Thanks
Ok everyone
Go to this site for info on 1750
https://www.mail-archive.com/[email protected]/msg69998.html
This will be helpful to everyone trying to receive this station
Thanks
Well what the heck. I'm going to check
it anyhow.
I've heard DRM on regular radios without
decoding gear or software. You don't
know what they're saying but
it's just for fun anyway.
Maybe he'll do some AM.
Ya never know.
Very Best Wishes,
And Thanks,
Bruce
P.S Oh, and Carl - simetimes you can hear
stuff inside the house (as you sure you have.)
I'm sure you'll get a receiving antenna outside
when you can.
Saturday noonish here in the Midwaste of The Homeland, more weather trouble heading this way after rendering heavy disruption on the mid to northern California coast, and since I'm Carl Blare I checked the shortwave band.
9395 kHz, the Global 24 frequency of WRMI from Okeechobee, Florida, noise only.
1750 kHz the digital test frequency from not far away Illinois, as mentioned by Bruce, noise only.
13,560 kHz, Tha Dood's announced test frequency using Part 15 specifications coming from Poca, West Virginia, noise only.
The noise across the shortwave band resembles digital buzz, but it's just background noise. Unless there is digital buzz across the whole band.
Carl, one thing I do indoors with receivers is
check WWV and CHU, and a few other cool
odds and ends.
It is fun to see how propagation changes from
day to day, week to week, etc. When WWV comes
in on 2500 kHz here in CT, I think that's really cool.
Here's a question - somebody said WWV was back
on 25 MHz? That's got to be a mistake.
It's funny what you take for granted. At the peak
of a past sunspot cycle - I listened to the VOA for
hours and hours everyday on 26.020 and 26.040.
40 over S9 indoors.
Those days will never come again, as we know.
And up near the MUF, wherever it might be,
you don't have to have a radio outside.
I like to just see where the MUF is, because
I'm a propagation guy.
One station you might want to try for Carl,
is CFRX on 6070 kHz. I believe it's the last
49 meter band Canadian station that is relaying
an AM BCB station - CFCF (??????) on 1010.
You know what, I'll have to check both of those.
But I do know that there is a Canadian 6070 BC station
on that can be heard during the day. Where is it(????)
I've gotten to the point where I can almost understand
SSB without a BFO, or atleast enough of it to be satisfied
with what I'm hearing.
Let me think about what you can monitor indoors, Carl.
By the way, I know you know where WWV is on the
dial. CHU is on 3330, 7850, and 14670 kHz. Because
of my distance from that station, I only hear the 14670 kHz
transmitter a couple times every 10 or 11 years. The skip is
wrong to hear it all the time here.
You can use the local oscillator of one radio to be the
BFO of another radio. It's not that easy, but I think
it's fun.
I used to listen to the 4 MHz maritime CW band when
I was about 16. It put me to sleep at night. The BFO
(for the portable SW radio I used to listen) was a Radio
Shack FlavorRadio. Remember those?
It was the second harmonic of the LO
when the radio was on the high end of the AM BCB.
For SSB it was too unstable but for CW you could
usually get it in good enough. Higher harmonics
were unusable. But a SW radio can be a BFO for
another SW radio.
Let me see if I can think of anything else.
By the way, for my entire lifetime, there has
been a RTTY station around 4 MHz at night.
As long as I can remember. I wonder what it
is? Does anybody know?
I'm still going to listen to 1750 kHz tonight,
regardless of what or whatnot is there.
Best Wishes,
Bruce
Bruce at 4:03 PM CST nothing at 6070 kHz.
25,000 kHz nothing.
WWV is coming in on 15,000 kHz.
If you whistle and talk at the same time it sounds like SSB with BFO set wrong. In fact, it may be impossible to do, but I'll try it on mic.
Well. that's cool.
I had a friend who could imitate
amplitude moulation with parasitic
oscillations by talking and blowing
out stored air in his cheeks.
Hilarious.
For you sax players, that might
be something like circular breathing,
but I'm not sure.
I've got 1750 kHz on now with the
Kaito KA-1103 hooked up to an
outside wire. If I can't hear it, I'll
bring out the Sony 2010.
In about 20 minutes, it will be 0000Z.
Maybe something will happen, maybe
it won't.
Bruce
