Utility / Who is the voice of "aviation weather" 10051 kHz?
« on: January 11, 2015, 0054 UTC »
Who is the voice of "aviation weather" on USB 10051 kHz? What's his name?  Where is he?

He seems to be the same voice for New York Radio and Gander radio on 10051 khz, heard easily in central Florida at 0030+ Z.

I've heard his voice for years (it seems).

It's the same voice, same delivery, same clear diction for as long as I've heard the broadcasts. There's a old post regard these volmet broadcasts that indicates it's a computerized voice. This makes sense as it's a mundane task to read all of the weather conditions.  If so, it's the most authentic and impressive synthesized human voice I've heard.

Thanks for identifying the signal: it's extremely likely you've identified it correctly.

 It was "by ear" that I guessed a 60 Hz tone.

Utility / 29788 kHz FM ute comms, Pennsylvania
« on: December 22, 2014, 1605 UTC »
At 1530+ Z  Monday Dec 22, 29788 mhz there's occasional FM voice communication between vans and a base with a 60 Hz hum on the carrier. Both sides of the communications have the same signal strength and the AC hum, so perhaps I'm hearing a repeater output.

Various people identifying themselves with their first name and a van number (i.e. van 43) indicating they are en-route to the Pittsburgh fire station for training.

Also, one person requested days for time off. They were approved.

Who is this?

Other / 29.7 to 30 mHz signals: who uses this band?
« on: November 16, 2014, 1500 UTC »
HF propagation has been favoring 10 meters and higher the past few weeks, but I rarely hear
any signals from 29.7 to 30 mHz except these data signals, copied November 16, 2014 at 1500z:

29759 kHz
29779 kHz
29869 kHz
29889 kHz
29949 kHz

I recall hearing some voice comms near 30 mHz in 1989, but not much else since.

Who's using that band?
What activity has been heard there?

Dag

Addendum: shortly after I posted, I found an occasional data signal not heard before on 29896  and 29901 kHz. See the link for a spectrum display. http://1drv.ms/1tXRP2z

On 29950 kHz,29890 kHz,and 29725 kHz at 1830z 6 SEP 2014, I copied similar signals with about a 150 Hz shift. See attached audio clip "29950".

In addition, the 29780 kHz signal seems to be about 300 Hz wide, and is heard in the "29780" audio file, attached.


I've copied these signals many times before and have always wondered what they are.

Chirpy CW signal "NA" each 30 seconds on 13555.0 kHz with Q5 S3 signal.

I heard these irregular dits zerobeat on 6822.0 kHz USB and zerobeat on 7001.0 kHz simultaneously for over 30 minutes - - for the duration of my monitoring,  the characteristics of the signal were consistent with the attached audio.

Attached is a 30 second audio clip recorded on 6822 kHz. There was a very faint MARS voice net up 1 kHz unconnected to the beeps.

Other / What is this signal?
« on: July 19, 2014, 0500 UTC »
Please listen to the short 9 second audio clip. What is that signal?

I've heard this sound for years. This one was recorded on 7657 khz, but it occurs all over the HF spectrum I think.

One thing about this particular recording is that the tone changes slightly with each burst -- something I've not noticed before.

Other / de 8ZMC 14108 kHz @ 0345z - not a ham.
« on: July 12, 2014, 0432 UTC »
Did 8ZMC replace H7DL?

The non-ham callsign 8ZMC was copied in CW on 14108 kHz at 0345z with Russian Morse code characters copied:  Ш (---- ),Ч (---.) Я (.-.-) in a long transmission. This is the same frequency as H7DL station.

Attached is a short audio of 8ZMC. The signal quality is similar to H7DL (see other post regarding H7DL).

The callsign 8ZMC may replace H7DL as it's also on 14108 kHz, but H7DL's frequently daily activity is not now seen on the Nordic Skimmer. H7DL activity will  show on the Nordic Skimmer with all transmissions on 14108 kHz or 28216 kHz (which is 14108 X 2 = 28216) ending on July 10.

Some of the 8ZMC intercept I copied:

« on: July 06, 2014, 1721 UTC »
I agree H7 is a Nicaragua prefix. But is it a ham? And was H7DL working an IZ9 station? I don't think so. Here's why:

I find no H7DL ham radio station via QRZ.com or a general Internet search. Also, I can't find any station listed as IZ9IZ.

I disagree on the CW interpretation:

The intercept clearly sounds as ".. E E Z 9 E E Z 9 E E Z 9 de H7DL H7DL".  That is, the callsign "H7DL" is properly spaced as to reflect a callsign, but the "E E Z 9..." is spaced differently and the list four characters in that group are "...E E Z 9". There's no "I" anywhere in the intercept.

In addition, I did a skimmer search for callsign H7DL here: http://www.voacap.com/skimmer/index.php?dx=h7dl&band=

As I write this, that search shows 32 CW skimmer reports as  "de H7DL" on  14108 kHz (+/- a few Hertz). Four of them are on 28216.2 kHz.   

Also, there's no IZ9IZ listed in a skimmer search.

There's more: I did a DXWATCH spot report for H7DL. There are none for H7DL. I would think at least one ham who works H7DL would list it in a spot somewhere, but I don't find any.  Yet, when I do spot search for my own callsign, I get a bunch of hits going back nearly 12 months.

Also, there's no Internet search result for H7DL and I'd think there'd be at least one comment if it were some sort of special event station.

So, who or what is H7DL? I don't thinks it's a ham radio station. He (or it) seems to be active on 14108 kHz CW generally between 0200z and 0800z and again from 0000z to 0400z.

Who is H7DL?

Sounds like commercial traffic. Mode is CW with poorly filtered note. No other transmissions heard after 0037z July 6 2014

The audio is 40 seconds long. I am unable to edit the attached audio clip (see below).
Intercept is below:
At 0 secs: K
At 21 secs:  R  K
At 40 secs:   E E Z 9 E E Z 9 E E Z 9 de H7DL  H7DL K

Other / Re: weird cw on 11223 lsb 5-3-14 0007z
« on: May 03, 2014, 0944 UTC »
I've been hearing it in central Florida for 24 hrs @ S9.

It's not CW: each "burst" or transmission is of equal length and there are generally 1 to 8 "bursts" per character, although occasionally I count 10 to 13 bursts per character.

A partial intercept" "... 8 4 1 4 6 1 4  3 1 1 9 3 1 1 3 10 ..."   There are occasional pauses.  Looking at the signal on a waterfall doesn't show any modulation on the signal such as in Pactor or other digital signals.


Perhaps this is a variant of a numbers station?
