de H7DL CW 14108.37 kHz 7/6/2014
« on: July 06, 2014, 0047 UTC »
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

14108 is at the top end of the CW portion of the 20 meter ham band.

I heard IZ9IZ IZ9IZ DE H7DL H7DL. Not so sure on the IZ9IZ part, but the Z and the 9 are definitely there.

I think you heard a ham from Nicaragua. H7 is one of the prefixes for Nicaragua.

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?

I just did a search on "14108 amateur radio pirate", and what came up in Google included a report by an international ham radio pirate and intruder reporting organisation, which has quarterly or monthly reports on intrusions into the ham bands by non-ham stations.

I found these reports by accident a few months ago researching the 'chanting' Indonesian ham pirates that intrude into the bottom part of the 40 Meter CW band.

There are several PDFs that show up in Google, all from the same organisation. The PDF reports have a summary at top, and then reports from hams in different countries, showing the non-ham intruders they have monitored.

On most of them, 14108 shows up frequently, and mostly it seems to be Russian Military, mostly CW, and using various identifiers.

One identifier used was "9YZZ" (5-25-2014);, other IDs were "3QZD" and "5VPM" (hrd in France 5/13 & 5/14 around 0400 UTC or so). "GPOH" and "ZCWB" were also heard on this frequency by a guy in the Netherlands. There are probably more. As I type this, I'm still going through one of the PDF reports.

You can find the PDFs, which are quite long, on Google.

Apparently there is also an intruder chat website, hasn't been used in a while, but in 2011 a guy heard a H67N callsign on 14108 also:
http://peditio.net/intruder/chat/00002011.htm
Scroll down the list about halfway you'll see it.

So, if this is Russian Military, they obviously use a lot of different calls, and the rest of the CW is in codes (ciphers).
